THE PROJECT
From an idea
to a real space.
A dedicated garden art studio in London, built with SIP panels and screw-pile foundations for year-round creative work.
A Fully Insulated SIP Artist Studio Designed for Year-Round Creative Work
Designed and built by TRJ Construction, this bespoke garden art studio creates a bright, comfortable and private workspace away from the main house. High-performance SIP construction provides excellent insulation and structural strength, while generous glazing brings natural light into the studio throughout the day.

Creating a Dedicated Space for Art & Creativity
This London garden art studio was built to give the client a separate, peaceful space for creative work away from the main house. The aim was to create a proper year-round studio, not a seasonal garden building, with a strong insulated structure, practical electrics and plenty of natural light.
Because the building sits in the garden, the design needed to feel connected to the outside while still working as a private professional workspace. TRJ Construction managed the build from structure through to the finished studio, using SIP construction to create a warm, rigid and energy-efficient building envelope.
Designed Around How Artists Actually Work
Natural light is one of the most important considerations when designing a garden art studio. Unlike a standard garden office, an artist's studio can benefit from carefully positioned glazing, rooflights and controlled artificial lighting to create consistent working conditions throughout the day.
Every TRJ garden studio can be designed around the client's preferred working position, garden orientation and type of artwork, whether the space is being used for painting, drawing, photography, crafts or other creative work.
Why SIP Panels Are Ideal for a Garden Art Studio
A creative studio needs to be comfortable throughout the year, not just during summer. TRJ Construction builds garden studios using Structural Insulated Panels rather than lightweight seasonal garden-building construction.
SIP construction creates a highly insulated building envelope, helping the studio maintain a comfortable temperature throughout winter and summer.
Artists can leave canvases, equipment and materials inside without treating the studio as a seasonal summer house.
The structural SIP system creates a rigid building capable of accommodating large areas of glazing, rooflights and bespoke internal layouts.
Continuous insulation helps reduce heat loss and makes heating or air conditioning more efficient.
TRJ typically uses 125mm SIP walls with 150mm SIP roof and floor systems on its premium garden-room builds.
What Can Be Included in a Garden Art Studio?
Windows, French doors, sliding doors and rooflights can be positioned around the studio's intended use.
Multiple sockets, dedicated circuits, task lighting and external lighting can be included.
Year-round climate control can be incorporated into the design.
A sink, water supply and drainage can be added for painters, ceramicists and crafts requiring washing facilities.
Hard-wired Ethernet and Wi-Fi solutions can be included for digital artists and content creators.
Wall storage, cabinetry and workspace layouts can be designed around equipment, materials and finished work.
How Much Does a Garden Art Studio Cost?
Our bespoke SIP garden rooms currently start from approximately £1,400 per square metre including VAT. A typical 15m² creative studio therefore starts from around £21,000, while a 20m² studio starts from around £28,000.
The final price depends on glazing, foundations, electrical requirements, external finishes, plumbing, air conditioning, rooflights and the level of internal fit-out required.
Because every art studio is designed around the client and the site, we provide a detailed quotation following an initial discussion and site assessment.
Do You Need Planning Permission for a Garden Art Studio?
Many garden art studios can be constructed under permitted development rights, provided the building complies with the relevant limits relating to location, height, size and use.
For example, an outbuilding positioned within two metres of a boundary will normally be limited to a maximum overall height of 2.5 metres under permitted development rules. Different rules can apply to listed buildings, conservation areas and properties where permitted development rights have been removed.
TRJ Construction can assess the proposed building and advise whether permitted development or a planning application is the appropriate route.
Built by TRJ Construction - From Structure to Finished Studio
TRJ Construction designs and builds insulated garden rooms from the ground up, including SIP structure, roof, glazing, exterior finish, electrics and internal completion. This gives clients one team responsible for the finished studio rather than a disconnected collection of trades.

How much does a garden art studio cost?
Our bespoke SIP garden studios start from approximately £1,400 per m² including VAT, with the final cost depending on size, glazing, foundations and specification.
Do I need planning permission for a garden art studio?
Many can be built under permitted development, although the permitted height, location and use must satisfy planning requirements. We assess this during the design stage.
Can a garden art studio be used throughout winter?
Yes. Our SIP studios are highly insulated and designed for year-round use, with heating or air conditioning available if required.
Can you install a sink in an art studio?
Yes. Water supply, drainage and a utility sink can be incorporated for painting, pottery and other creative work.
Yes. Rooflights can provide excellent natural daylight and are particularly useful where wall glazing is restricted.
Can you build a studio for a professional artist?
Yes. Studios can be designed around professional requirements including specialist lighting, electrical loads, storage, plumbing, ventilation and internet connectivity.
TRJ Construction builds bespoke garden studios across North London, Hertfordshire, Essex, Buckinghamshire and surrounding areas.
