JMP’s Garden Rooms are high-spec, fully insulated outbuildings built to housing standards. Available as our sleek Garden Pod or larger Studio, they create versatile extra space in your garden. Common uses include home offices, gyms, art studios, guest bedrooms (annexes), music/leisure rooms or wellness retreats. Because we build like a house – not a shed – you get a warm, secure space to work or relax year-round. We serve London, Hertfordshire and surrounding areas, turning gardens into comfortable, functional spaces.
We offer two main models, each in multiple sizes to fit your garden. The JMP Pod is our most popular compact garden office or room, featuring a sleek overhanging canopy and available in sizes from 10 m² up to 20 m². The JMP Studio is a larger annexe or guest room (14–20 m²), complete with an integrated shower room for added convenience. Both models can be fully customised – from layout and cladding to colours and flooring – to suit your style and space.
Every JMP Garden Room includes high-end specifications for comfort and durability. We build on screw-pile or pad foundations suited to your soil. The structure uses treated C24 timber with 100 mm Rockwool insulation in the floor, walls and roof. Interiors are dry-lined and plastered; exteriors feature a breathable EPDM flat roof with guttering, ventilated wall construction, and your choice of cladding. All doors and windows are double-glazed uPVC (French, sliding, or bifold). Every room includes underfloor electric heating and a full electrical package (lights, sockets, switches). In short, it’s a fully insulated, weatherproof mini-house: warm in winter, cool in summer – and backed by our industry-leading guarantees.
Yes, our buildings are fully insulated to ensure comfort year-round—warm in winter and cool in summer.
Absolutely. In addition to our standard Pod and Studio, we design fully bespoke garden buildings from scratch. Our team works with you to create a made-to-measure structure tailored to your lifestyle – from layout and lighting to external cladding and interior finishes. If you can imagine it, we can build it.
In most cases, planning permission is not required—our garden rooms are specifically designed to comply with UK Permitted Development rules.If you choose a Garden Room or Garden Office under 2.5 m in height, and your property is not listed or located in a designated area, you can typically place it anywhere in your rear or side garden without needing a planning application. Please refer to our dedicated tab for full details on planning regulations.
In many cases, no—but it depends on the size and intended use of the building. Outbuildings under 15 m² that do not include sleeping accommodation are generally exempt. Those between 15–30 m² may also be exempt, provided they are at least 1 m from any boundary.
However, if you plan to install plumbing or use the space as living accommodation, Building Regulations may apply.
Regardless of the requirements, all JMP buildings are constructed to housing-grade standards and comply with key regulations, including Part A (structure), Part L (energy efficiency), and Part P (electrical safety). If your project requires formal Building Regulations approval, we’ll guide you through the process.

Absolutely. You can include a WC or shower room in your garden room, though this usually involves additional plumbing and may require Building Regulations approval. We’ll assess your specific needs and guide you through the process, handling all necessary installations and compliance steps.
At JMP, we offer some of the longest guarantees in the industry to give you complete peace of mind. Every garden room comes with a 20-year structural guarantee (covering the frame), a 10-year guarantee on doors and windows, a 10-year roofing guarantee, a 10-year cladding guarantee, and a 3-month warranty on fittings such as lights, handles, and heating. Your investment is built to last—and backed for decades.
Our in-house team manages the entire installation process, typically completing your garden room in just 10 working days (weather and access permitting) from the start on site. Once designs and approvals are finalised, we take care of everything—from groundwork and construction to electrics and finishing touches.
Before we begin, we’ll provide guidance on site preparation and confirm any access requirements. After installation, we conduct a full handover and quality check. Most of our clients are pleasantly surprised by how quickly their new space is ready to enjoy.

We handle all foundation work using either screw piles or Swift-Pad systems, depending on the ground conditions. All we ask is that the area is cleared of any plants, debris, or garden furniture before we begin.
During our free site survey, we’ll assess the space, confirm access, and address any site-specific requirements. There’s no need for you to pour a concrete slab or organise groundwork—we take care of it all as part of our comprehensive service.

Yes, relocating your garden room is possible, although it can be a complex process. We can handle this for you, but it would require a custom quote based on your specific circumstances. If relocation is something you may want in the future, please let us know before construction begins, so we can factor it into the design.
All materials are delivered directly to your site, and the Garden Room is constructed on-site by our expert team. This method ensures a precise fit and allows us to work efficiently, even in gardens with limited access.
Fire resistance depends on the cladding option you choose from our range:
- Fibre Cement Cladding offers high fire resistance and is non-combustible.
- Smooth Composite Cladding provides good fire performance, depending on the specific product.
- Thermowood Timber Cladding is durable but, as a natural material, it is not non-combustible.
At JMP, we bring over 30 years of experience in the homebuilding and renovation industry, with a strong focus on timber-framed construction. Our background spans full-scale residential builds, complex home extensions, and structural renovations—giving us deep expertise in craftsmanship, structural integrity, and energy efficiency.
Drawing on this foundation, we’ve developed a specialised approach to Garden Rooms and Garden Offices, combining architectural precision, durable materials, and modern construction techniques. Every structure we create reflects the same high standards we apply to full homes, ensuring long-lasting performance, comfort, and visual appeal.
Whether you're looking for a stylish office, a multi-purpose space, or a fully equipped guest suite, JMP has the technical knowledge and practical experience to bring your vision to life.

If you choose composite or fibre cement cladding, maintenance is minimal. These materials are highly durable and only require an occasional wash with soapy water (avoid power washing) to remove bird droppings or surface dirt.
We also recommend sweeping the roof once a year to clear leaves and debris, along with routine care such as cleaning the glass and polishing handles and hinges — that’s typically all that’s needed to keep your Garden Room looking its best.
If you’ve chosen Thermowood timber cladding, it will require a bit more care. To retain its original colour and finish, we recommend staining it every 3–5 years. Alternatively, you can allow the timber to weather naturally to a grey-silver patina over time. This natural ageing process can take several years and may result in a patchy appearance during the transition.

If you want to put up small detached buildings such as a garden shed, garden room or summerhouse in your garden, Building Regulations (except Part P for Electrical works) will not normally apply if the floor area of the building is less than 15 square metres INTERNALLY and contains NO sleeping accommodation.
If the INTERNAL floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval, providing that the building contains NO sleeping accommodation, and is either at least one metre from any boundary, or it is constructed of substantially non-combustible materials.
- Building Regulations do not usually apply unless you want to sleep in it
- Under 15m2 internal floor area can be installed close to any rear boundary
- Over 15m2 and up to 30m2 needs to be a minimum 1m from any boundary

Building Regulations
Complying with Building Regulations
Therefore in general, Garden Buildings do not need to comply with Building Regulations (other than Part P for Electrical works). However, at JMP Contractors & Engineers we believe it is good practice to work to Part A of the Regulations, to provide assurance to our customers that our buildings are not only BUILT TO LAST but are also structurally safe and sound.
Part A of the Regulations for structural integrity is fully complied with, ensuring that the building is constructed so that combined dead loads (weight of structural elements), imposed loads (snow, maintenance activities, etc) and wind loads are accounted for. Issues addressed cover elements such as the size and bearing of roof timbers relative to the unsupported roof span per guidance issued by NHBC and TRADA.
Under Regulation 21 of the Building Regulations 2010, Part L (Conservation of Fuel and Power) does not apply to buildings with a total useful floor area of less than 50m², provided they are detached and unheated.
Part L governs the energy efficiency of buildings and takes into account the performance of key thermal elements — including the insulation values (U-values) of walls, roofs, floors, windows, and doors. It sets minimum standards to reduce energy consumption and ensure buildings are constructed or renovated to meet modern thermal efficiency requirements.

Our standard Garden Buildings are electrically equipped and wired internally only. Although we are happy to quote for the installation of an armoured cable from the house to the Studio as required, it is not included in our standard Garden Room prices due to the many on-site variables such as: distance from the main house to the Garden Room; footpaths, patios, driveways and obstacles in the way etc. This work can be carried out either by a local electrical contractor or by our in-house electrician for an additional cost. All supply cables need to be Armoured, sized to account for Voltage drop and if buried, must be to a sufficient depth to avoid future harm - see Legislation HERE
Please note
We are constantly reviewing our specifications to ensure that all our Garden Rooms offer the best compromise between cost and operational comfort. Due to the ever increasing costs of complying with the demands of the Kyoto agreement for increased levels of insulation, we have no option but to offer to meet the above targets at an additional cost over and above our standard pricing.
Part P In the case of Garden Buildings Part P applies and any work is notifiable to the Local Authority. Work can be self-certified by an Electrical Installer who is registered as a competent person using a BS7671 electrical installation certificate for every job they undertake, with a copy given to the householder. This is supplied by JMP Contractors & Engineers where we are contracted to do this work.
Consequently, Part P for Electrical installations is complied with in so far as JMP Contractors & Engineers is contracted or otherwise to carry-out either internal or external works, or both as the case may be.

Planning Permission
Outbuildings are generally considered to be permitted development under Class E, and do not need Planning Permission, subject to a number of limits and conditions.
The most important factors are:
NOTE: All our buildings are manufactured to meet the 2.5m height Planning restriction.
Outbuildings are generally considered to be permitted development under Class E, and do not need Planning Permission, subject to a number of limits and conditions.
The most important factors are:
- That the building is no higher than 2.5m from the bottom of the building to the top of the roof
- That you do not take up more than 50% of your garden area with this or any other buildings
- It is not to be used for living or sleeping accommodation
NOTE: All our buildings are manufactured to meet the 2.5m height Planning restriction.
Planning Regulations
DEFINITION of 'Permitted Development':
'The provision of any outbuilding within the curtilage of the dwelling for a purpose incidental to the enjoyment of the dwelling, or the maintenance, improvement or alteration of such building or enclosure'.
Essentially, this means that so long as the purpose of the development is incidental to the enjoyment of the dwelling it will be classed as Permitted
Development except in the following circumstances:
Essentially, this means that so long as the purpose of the development is incidental to the enjoyment of the dwelling it will be classed as Permitted
Development except in the following circumstances:
- You are not allowed an outbuilding which projects forward of the front elevation of the original house.
- Any outbuilding must be single storey and have a maximum eaves height of no more than 2.5 metres. The maximum overall height must not be more than 4 metres if a dual pitched roof is specified, or 3 metres for any other roof
- If the outbuilding is to be positioned within 2 metres of the property boundary, no part of it shall exceed 2.5 metres in height. So below 2.5m height it can be positioned as close to the boundary as is practical.
- No balconies or verandas are allowed on an outbuilding without Planning Permission.
- Decking or other raised platforms can be fitted around the outbuilding, but only up to a maximum height of 300mm.
- Any outbuilding must not be used as self-contained living accommodation, and must not have a TV, or Satellite type of aerial. Planning Permission will be required in these cases.
- Outbuildings and other additions must not take up more than half the area of land around the "original house". “Original house” means the house as it was first built, or as it was on 1st July 1948 (If built before that date). Extensions, timber sheds and all other outbuildings must be included when calculating this limit. Although you may not have built an extension, the previous owner could have done, and this needs to be included in calculating the overall limit.
- On designated land, (areas of Outstanding Natural Beauty, National Parks, the Broads, Conservation Areas and World Heritage Sites), the maximum size of an outbuilding will be limited to 10 square metres and must be 20m from any wall of the house.
- On designated land (AONB etc), outbuildings at the side of the house will require planning permission.
- If the original building has Listed Status, all outbuildings will need full planning permission.
This guidance applies to planning regulations in England only. Policy for Scotland and Wales may differ slightly please check with your Local Authority.

In addition, although many of our Garden Rooms are designed to be below the 2.5m maximum height allowance for Permitted Development, allowing buildings to be placed right up against a boundary, please note that we usually need a minimum of 500mm clearance all around our buildings to facilitate assembly and Health and Safety precautions.

JMP’s Garden Rooms are high-spec, fully insulated outbuildings built to housing standards. Available as our sleek Garden Pod or larger Studio, they create versatile extra space in your garden. Common uses include home offices, gyms, art studios, guest bedrooms (annexes), music/leisure rooms or wellness retreats. Because we build like a house – not a shed – you get a warm, secure space to work or relax year-round. We serve London, Hertfordshire and surrounding areas, turning gardens into comfortable, functional spaces.
We offer two main models, each in multiple sizes to fit your garden. The JMP Pod is our most popular compact garden office or room, featuring a sleek overhanging canopy and available in sizes from 10 m² up to 20 m². The JMP Studio is a larger annexe or guest room (14–20 m²), complete with an integrated shower room for added convenience. Both models can be fully customised – from layout and cladding to colours and flooring – to suit your style and space.
Every JMP Garden Room includes high-end specifications for comfort and durability. We build on screw-pile or pad foundations suited to your soil. The structure uses treated C24 timber with 100 mm Rockwool insulation in the floor, walls and roof. Interiors are dry-lined and plastered; exteriors feature a breathable EPDM flat roof with guttering, ventilated wall construction, and your choice of cladding. All doors and windows are double-glazed uPVC (French, sliding, or bifold). Every room includes underfloor electric heating and a full electrical package (lights, sockets, switches). In short, it’s a fully insulated, weatherproof mini-house: warm in winter, cool in summer – and backed by our industry-leading guarantees.
Yes, our buildings are fully insulated to ensure comfort year-round—warm in winter and cool in summer.
Absolutely. In addition to our standard Pod and Studio, we design fully bespoke garden buildings from scratch. Our team works with you to create a made-to-measure structure tailored to your lifestyle – from layout and lighting to external cladding and interior finishes. If you can imagine it, we can build it.
In most cases, planning permission is not required—our garden rooms are specifically designed to comply with UK Permitted Development rules.If you choose a Garden Room or Garden Office under 2.5 m in height, and your property is not listed or located in a designated area, you can typically place it anywhere in your rear or side garden without needing a planning application. Please refer to our dedicated tab for full details on planning regulations.
In many cases, no—but it depends on the size and intended use of the building. Outbuildings under 15 m² that do not include sleeping accommodation are generally exempt. Those between 15–30 m² may also be exempt, provided they are at least 1 m from any boundary.
However, if you plan to install plumbing or use the space as living accommodation, Building Regulations may apply.
Regardless of the requirements, all JMP buildings are constructed to housing-grade standards and comply with key regulations, including Part A (structure), Part L (energy efficiency), and Part P (electrical safety). If your project requires formal Building Regulations approval, we’ll guide you through the process.

Absolutely. You can include a WC or shower room in your garden room, though this usually involves additional plumbing and may require Building Regulations approval. We’ll assess your specific needs and guide you through the process, handling all necessary installations and compliance steps.
At JMP, we offer some of the longest guarantees in the industry to give you complete peace of mind. Every garden room comes with a 20-year structural guarantee (covering the frame), a 10-year guarantee on doors and windows, a 10-year roofing guarantee, a 10-year cladding guarantee, and a 3-month warranty on fittings such as lights, handles, and heating. Your investment is built to last—and backed for decades.
Our in-house team manages the entire installation process, typically completing your garden room in just 10 working days (weather and access permitting) from the start on site. Once designs and approvals are finalised, we take care of everything—from groundwork and construction to electrics and finishing touches.
Before we begin, we’ll provide guidance on site preparation and confirm any access requirements. After installation, we conduct a full handover and quality check. Most of our clients are pleasantly surprised by how quickly their new space is ready to enjoy.

We handle all foundation work using either screw piles or Swift-Pad systems, depending on the ground conditions. All we ask is that the area is cleared of any plants, debris, or garden furniture before we begin.
During our free site survey, we’ll assess the space, confirm access, and address any site-specific requirements. There’s no need for you to pour a concrete slab or organise groundwork—we take care of it all as part of our comprehensive service.

Yes, relocating your garden room is possible, although it can be a complex process. We can handle this for you, but it would require a custom quote based on your specific circumstances. If relocation is something you may want in the future, please let us know before construction begins, so we can factor it into the design.
All materials are delivered directly to your site, and the Garden Room is constructed on-site by our expert team. This method ensures a precise fit and allows us to work efficiently, even in gardens with limited access.
Fire resistance depends on the cladding option you choose from our range:
- Fibre Cement Cladding offers high fire resistance and is non-combustible.
- Smooth Composite Cladding provides good fire performance, depending on the specific product.
- Thermowood Timber Cladding is durable but, as a natural material, it is not non-combustible.

If you choose composite or fibre cement cladding, maintenance is minimal. These materials are highly durable and only require an occasional wash with soapy water (avoid power washing) to remove bird droppings or surface dirt.
We also recommend sweeping the roof once a year to clear leaves and debris, along with routine care such as cleaning the glass and polishing handles and hinges — that’s typically all that’s needed to keep your Garden Room looking its best.
If you’ve chosen Thermowood timber cladding, it will require a bit more care. To retain its original colour and finish, we recommend staining it every 3–5 years. Alternatively, you can allow the timber to weather naturally to a grey-silver patina over time. This natural ageing process can take several years and may result in a patchy appearance during the transition.

JMP’s Garden Rooms are high-spec, fully insulated outbuildings built to housing standards. Available as our sleek Garden Pod or larger Studio, they create versatile extra space in your garden. Common uses include home offices, gyms, art studios, guest bedrooms (annexes), music/leisure rooms or wellness retreats. Because we build like a house – not a shed – you get a warm, secure space to work or relax year-round. We serve London, Hertfordshire and surrounding areas, turning gardens into comfortable, functional spaces.
We offer two main models, each in multiple sizes to fit your garden. The JMP Pod is our most popular compact garden office or room, featuring a sleek overhanging canopy and available in sizes from 10 m² up to 20 m². The JMP Studio is a larger annexe or guest room (14–20 m²), complete with an integrated shower room for added convenience. Both models can be fully customised – from layout and cladding to colours and flooring – to suit your style and space.
Every JMP Garden Room includes high-end specifications for comfort and durability. We build on screw-pile or pad foundations suited to your soil. The structure uses treated C24 timber with 100 mm Rockwool insulation in the floor, walls and roof. Interiors are dry-lined and plastered; exteriors feature a breathable EPDM flat roof with guttering, ventilated wall construction, and your choice of cladding. All doors and windows are double-glazed uPVC (French, sliding, or bifold). Every room includes underfloor electric heating and a full electrical package (lights, sockets, switches). In short, it’s a fully insulated, weatherproof mini-house: warm in winter, cool in summer – and backed by our industry-leading guarantees.
Yes, our buildings are fully insulated to ensure comfort year-round—warm in winter and cool in summer.
Absolutely. In addition to our standard Pod and Studio, we design fully bespoke garden buildings from scratch. Our team works with you to create a made-to-measure structure tailored to your lifestyle – from layout and lighting to external cladding and interior finishes. If you can imagine it, we can build it.
In most cases, planning permission is not required—our garden rooms are specifically designed to comply with UK Permitted Development rules.If you choose a Garden Room or Garden Office under 2.5 m in height, and your property is not listed or located in a designated area, you can typically place it anywhere in your rear or side garden without needing a planning application. Please refer to our dedicated tab for full details on planning regulations.
In many cases, no—but it depends on the size and intended use of the building. Outbuildings under 15 m² that do not include sleeping accommodation are generally exempt. Those between 15–30 m² may also be exempt, provided they are at least 1 m from any boundary.
However, if you plan to install plumbing or use the space as living accommodation, Building Regulations may apply.
Regardless of the requirements, all JMP buildings are constructed to housing-grade standards and comply with key regulations, including Part A (structure), Part L (energy efficiency), and Part P (electrical safety). If your project requires formal Building Regulations approval, we’ll guide you through the process.

Absolutely. You can include a WC or shower room in your garden room, though this usually involves additional plumbing and may require Building Regulations approval. We’ll assess your specific needs and guide you through the process, handling all necessary installations and compliance steps.
At JMP, we offer some of the longest guarantees in the industry to give you complete peace of mind. Every garden room comes with a 20-year structural guarantee (covering the frame), a 10-year guarantee on doors and windows, a 10-year roofing guarantee, a 10-year cladding guarantee, and a 3-month warranty on fittings such as lights, handles, and heating. Your investment is built to last—and backed for decades.
Our in-house team manages the entire installation process, typically completing your garden room in just 10 working days (weather and access permitting) from the start on site. Once designs and approvals are finalised, we take care of everything—from groundwork and construction to electrics and finishing touches.
Before we begin, we’ll provide guidance on site preparation and confirm any access requirements. After installation, we conduct a full handover and quality check. Most of our clients are pleasantly surprised by how quickly their new space is ready to enjoy.

We handle all foundation work using either screw piles or Swift-Pad systems, depending on the ground conditions. All we ask is that the area is cleared of any plants, debris, or garden furniture before we begin.
During our free site survey, we’ll assess the space, confirm access, and address any site-specific requirements. There’s no need for you to pour a concrete slab or organise groundwork—we take care of it all as part of our comprehensive service.

Yes, relocating your garden room is possible, although it can be a complex process. We can handle this for you, but it would require a custom quote based on your specific circumstances. If relocation is something you may want in the future, please let us know before construction begins, so we can factor it into the design.
All materials are delivered directly to your site, and the Garden Room is constructed on-site by our expert team. This method ensures a precise fit and allows us to work efficiently, even in gardens with limited access.
Fire resistance depends on the cladding option you choose from our range:
- Fibre Cement Cladding offers high fire resistance and is non-combustible.
- Smooth Composite Cladding provides good fire performance, depending on the specific product.
- Thermowood Timber Cladding is durable but, as a natural material, it is not non-combustible.

In brief:
If you want to put up small detached buildings such as a garden shed, garden room or summerhouse in your garden, Building Regulations (except Part P for Electrical works) will not normally apply if the floor area of the building is less than 15 square metres INTERNALLY and contains NO sleeping accommodation.
If the INTERNAL floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval, providing that the building contains NO sleeping accommodation, and is either at least one metre from any boundary, or it is constructed of substantially non-combustible materials.
- Building Regulations do not usually apply unless you want to sleep in it
- Under 15m2 internal floor area can be installed close to any rear boundary
- Over 15m2 and up to 30m2 needs to be a minimum 1m from any boundary

Building Regulations
Complying with Building Regulations
Therefore in general, Garden Buildings do not need to comply with Building Regulations (other than Part P for Electrical works). However, at JMP Contractors & Engineers we believe it is good practice to work to Part A of the Regulations, to provide assurance to our customers that our buildings are not only BUILT TO LAST but are also structurally safe and sound.
Part A of the Regulations for structural integrity is fully complied with, ensuring that the building is constructed so that combined dead loads (weight of structural elements), imposed loads (snow, maintenance activities, etc) and wind loads are accounted for. Issues addressed cover elements such as the size and bearing of roof timbers relative to the unsupported roof span per guidance issued by NHBC and TRADA.
Under Regulation 21 of the Building Regulations 2010, Part L (Conservation of Fuel and Power) does not apply to buildings with a total useful floor area of less than 50m², provided they are detached and unheated.
Part L governs the energy efficiency of buildings and takes into account the performance of key thermal elements — including the insulation values (U-values) of walls, roofs, floors, windows, and doors. It sets minimum standards to reduce energy consumption and ensure buildings are constructed or renovated to meet modern thermal efficiency requirements.

Our standard Garden Buildings are electrically equipped and wired internally only. Although we are happy to quote for the installation of an armoured cable from the house to the Studio as required, it is not included in our standard Garden Room prices due to the many on-site variables such as: distance from the main house to the Garden Room; footpaths, patios, driveways and obstacles in the way etc. This work can be carried out either by a local electrical contractor or by our in-house electrician for an additional cost. All supply cables need to be Armoured, sized to account for Voltage drop and if buried, must be to a sufficient depth to avoid future harm - see Legislation HERE
Please note
We are constantly reviewing our specifications to ensure that all our Garden Rooms offer the best compromise between cost and operational comfort. Due to the ever increasing costs of complying with the demands of the Kyoto agreement for increased levels of insulation, we have no option but to offer to meet the above targets at an additional cost over and above our standard pricing.
Part P In the case of Garden Buildings Part P applies and any work is notifiable to the Local Authority. Work can be self-certified by an Electrical Installer who is registered as a competent person using a BS7671 electrical installation certificate for every job they undertake, with a copy given to the householder. This is supplied by JMP Contractors & Engineers where we are contracted to do this work.
Consequently, Part P for Electrical installations is complied with in so far as JMP Contractors & Engineers is contracted or otherwise to carry-out either internal or external works, or both as the case may be.

Planning Permission
Outbuildings are generally considered to be permitted development under Class E, and do not need Planning Permission, subject to a number of limits and conditions.
The most important factors are:
NOTE: All our buildings are manufactured to meet the 2.5m height Planning restriction.
Outbuildings are generally considered to be permitted development under Class E, and do not need Planning Permission, subject to a number of limits and conditions.
The most important factors are:
- That the building is no higher than 2.5m from the bottom of the building to the top of the roof
- That you do not take up more than 50% of your garden area with this or any other buildings
- It is not to be used for living or sleeping accommodation
NOTE: All our buildings are manufactured to meet the 2.5m height Planning restriction.
Planning Regulations
DEFINITION of 'Permitted Development':
'The provision of any outbuilding within the curtilage of the dwelling for a purpose incidental to the enjoyment of the dwelling, or the maintenance, improvement or alteration of such building or enclosure'.
Essentially, this means that so long as the purpose of the development is incidental to the enjoyment of the dwelling it will be classed as Permitted
Development except in the following circumstances:
Essentially, this means that so long as the purpose of the development is incidental to the enjoyment of the dwelling it will be classed as Permitted
Development except in the following circumstances:
- You are not allowed an outbuilding which projects forward of the front elevation of the original house.
- Any outbuilding must be single storey and have a maximum eaves height of no more than 2.5 metres. The maximum overall height must not be more than 4 metres if a dual pitched roof is specified, or 3 metres for any other roof
- If the outbuilding is to be positioned within 2 metres of the property boundary, no part of it shall exceed 2.5 metres in height. So below 2.5m height it can be positioned as close to the boundary as is practical.
- No balconies or verandas are allowed on an outbuilding without Planning Permission.
- Decking or other raised platforms can be fitted around the outbuilding, but only up to a maximum height of 300mm.
- Any outbuilding must not be used as self-contained living accommodation, and must not have a TV, or Satellite type of aerial. Planning Permission will be required in these cases.
- Outbuildings and other additions must not take up more than half the area of land around the "original house". “Original house” means the house as it was first built, or as it was on 1st July 1948 (If built before that date). Extensions, timber sheds and all other outbuildings must be included when calculating this limit. Although you may not have built an extension, the previous owner could have done, and this needs to be included in calculating the overall limit.
- On designated land, (areas of Outstanding Natural Beauty, National Parks, the Broads, Conservation Areas and World Heritage Sites), the maximum size of an outbuilding will be limited to 10 square metres and must be 20m from any wall of the house.
- On designated land (AONB etc), outbuildings at the side of the house will require planning permission.
- If the original building has Listed Status, all outbuildings will need full planning permission.
This guidance applies to planning regulations in England only. Policy for Scotland and Wales may differ slightly please check with your Local Authority.

In addition, although many of our Garden Rooms are designed to be below the 2.5m maximum height allowance for Permitted Development, allowing buildings to be placed right up against a boundary, please note that we usually need a minimum of 500mm clearance all around our buildings to facilitate assembly and Health and Safety precautions.
