Our composite cladding garden room builds are amongst our most popular garden room options, offering homeowners the perfect combination of a modern finish with long-lasting strength.

The colour-stable boards resist fading or warping, making them suitable for garden rooms you intend to make full use of year-round. Our composite garden rooms can also be fully insulated and fitted with electrics, heating, plumbing and more.

100mm Structural Insulated Panels (SIPs) – Used throughout the walls, floor and roof for strength, insulation and year-round comfort (not compatible with skylights or sky lantern options). Upgrade to 150mm SIPS available.

Damp Proof Membrane and Breathable Membrane – Protects the structure from moisture while allowing airflow.

UPVC Windows and Doors – Supplied in your chosen size, design and colour for durability and energy efficiency. Upgrade to aluminium bi-fold doors available.

Fire-Rated Materials – Installed on any wall within 1m of a boundary to comply with building regulations.

UPVC Fascias, Soffits and Guttering – Provide a clean, low-maintenance finish. Available in your chosen colour.

Plastered Internal Finish – Smooth plastered walls as standard. Flooring and skirting quoted separately.

Internal and External Electrics – Installed as desired, including first and second fix.

EPDM Rubber Roof – Long-lasting, watertight roof covering for maximum protection and minimal upkeep.

Your Choice of Cladding Colour – Our composite cladding exterior finish option is available in 8 colours: light grey, coffee, ivory, redwood, charcoal, stone grey, teak and olive green.

Aluminium Bi-fold Doors – Open up your space with wide, modern access and improved natural light.

Skylights and Roof Lanterns – Boost natural daylight and create a more open feel.

Insulation – 100mm SIP construction already provides excellent insulation, but additional thermal upgrades are available for enhanced efficiency. Additional soundproofing is also available, as well as upgrades to 150mm SIPs.

Electrical Setup – Comprehensive internal and external electrical systems, including lighting, sockets and power points.

Plumbing – Add a fully-functional kitchen, sink, toilet or shower to create a fully functional annexe or workspace.

Partition Walls – Divide your garden room into distinct areas such as an office, gym or living space.

Plastering and Internal Cladding – Plastered internally as standard with alternative interior finishes such as UPVC panels and timber cladding available on request to suit individual requirements. Skirting and trims can also be added on request.

Internal Flooring – Laminate flooring and skirting options available.

Roof Overhang – Extend the roofline 1 – 2ft to create a sheltered outdoor space or additional visual interest. Additional cost for overhangs larger than 1 – 2 ft.

Canopy Extension – Add covered outdoor seating or storage space for year-round usability.

Groundworks – Slabbed base (size dependent) or a concrete pad available, with ground screws offered on request.

Each of our composite garden rooms is delivered as a fully finished installation carried out by our own skilled team. You won’t receive a flat pack or be left to complete the build yourself. Instead, we oversee the entire project from the initial groundwork through to the final touches, so your new space is ready to enjoy as soon as we leave.

Before any work begins, we arrange a complimentary site assessment which is where we’ll assess your garden, review your specifications and start to plan for your build.

Should your project require planning permission we can provide guidance and support throughout the process helping you meet local requirements without unnecessary delays or complications.

Once everything is agreed we handle all stages of the build. This includes preparing the base assembling the insulated structure and completing the internal finishes you have selected. The exterior is wrapped in high quality composite cladding which offers lasting colour stability weather resistance and a clean contemporary appearance.

Your composite garden room is constructed on site using carefully selected materials and refined craftsmanship resulting in a durable energy efficient space tailored to your needs.

Typical lead time is around 2 – 3 weeks for all custom garden room installations.

Can I use a garden room as an office?

Working from home has become increasingly popular over the last few years with garden rooms being commonly renovated to be used as a home office space. A garden room allows for an office at home whilst being away from day-to-day distractions you’ll find in your actual home. Due to the warmth and energy efficiency of our SIP Garden Rooms, you’ll be able to enjoy a comfortable, yet productive home office setup.

Can I have a garden room as an extension?

Yes, our extensions are built using Structural Insulated Panels (SIP’s). Our SIP Extensions have a wide range of external finishes from Composite Cladding, Fibre Cement Cladding, Canadian Red Western Cedar, Render and Brick Slips in order to either match or complement the existing structure.

Do you need planning permission for a garden room?

Your bespoke garden rooms do not typically need planning permission so long as the build is less than 2.5m in height when located within 2m of a boundary, is no larger than 30sqm and does not take up more than 50% of the total garden space. The sides of the build within 1m of a boundary must also be finished with a fire-resistant material such as Fire-Retardant Metal Sheeting or Fibre Cement Cladding.

The intended use of the build will also determine whether planning permission is required. If the build is to be used as a liveable dwelling or have running water and a bathroom, planning permission will be required.

In conservation areas and areas of outstanding natural beauty rules often differ and should be checked accordingly. We always advise checking with your local council first if you are unsure.

How do I keep my garden room warm in the winter?

Our custom made garden rooms are built using Structural Insulated Panels (SIP’s). These panels consist of an insulating foam core sandwiched between two structural facings. The insulating core of the panels will keep your garden room cool in the summer and warm in the winter, providing your space with unrivalled insulation and air tightness alike.

Most of our customers will also opt for a small panel heater to warm the room if required during the colder months.

Can I put a toilet in my garden room?

Yes you can have a toilet installed in your garden room. From a small single toilet to a large, fitted bathroom, whatever size washroom you need will be able to be installed into your garden room however this would require planning permission. We offer full plumbing and bathroom installation as extras, so we can take care of this with ease.

How can I get Wi-Fi in my garden room?

An Ethernet cable can be installed at the time of the electrical installation at an additional cost if requested.

How much value does a garden room add?

Garden Rooms can add value to a property however the amount varies depending on the size, quality and function of the actual garden room. A custom made garden room is also an attractive selling point for potential buyers due to the added space it offers either for storage or as an actual residential or commercial dwelling.
