Size & Layout
From compact home offices to multi-purpose rooms, you choose the shape, size and function. We adjust layouts to match your property and how you want to use the space.
Composite Garden Buildings
Composite garden buildings offer a smart, stylish solution for adding space to your home without the upkeep of traditional timber. Whether you’re after a garden office, creative studio, home gym or storage room, composite structures are engineered for durability and efficiency. They blend modern materials with practical design, offering a sleek finish, strong insulation and excellent weather protection.
Unlike timber, they don’t require staining or sealing, making them ideal for homeowners who want a functional space without ongoing maintenance. Every structure is prefabricated and built for quick, clean installation.
Modern Garden Rooms That Last
Composite garden buildings are purpose-built for everyday use, offering a clean, contemporary design with materials that resist wear and tear. Whether used as a work base, fitness area or retreat, these rooms stay looking fresh for years with minimal upkeep. The sleek panels used in composite construction won’t warp, rot or fade like untreated wood, and their modular structure makes them easy to configure and expand.
At Noah, we manufacture every room in the UK using high-grade composite panels and a sealed structural system designed for strength and comfort.

Design a Composite Garden Building to Suit You
These buildings offer more than just flexibility in layout. With composite panels, the structure can be made in sleek, uniform finishes that blend well with modern gardens. We design each room to suit your space and needs, whether that means a small pod tucked in the corner or a larger structure split into zones. Everything from the base to the roof is tailored to how you plan to use it. Our team helps guide the decision-making, ensuring the result fits both practically and aesthetically.
02.
Style & Finish
Choose from flat or pitched roof styles and a selection of finishes that mimic wood grain or embrace a clean, modern look. Add interior wall panels, flooring, lighting and fittings to personalise the inside.
03.
Performance Upgrades
Enhance comfort with heating, cooling, acoustic insulation or smart lighting. Add USB sockets, blinds, or climate control depending on how you want the space to perform.
04.
Doors & Windows
Opt for floor-to-ceiling glass, sliding or bifold doors, and any combination of fixed or opening windows to balance light, privacy and ventilation.
Built for Performance and Simplicity
Composite garden buildings are made to perform with very little intervention. From structural integrity to thermal regulation, these rooms are robust and ready for year-round use. The materials used resist rot, moisture, and UV fading while supporting full electrical and heating installation. With minimal upkeep, they continue to function and look good for years to come. They’re also ideal for those looking to reduce their home maintenance commitments while still enjoying the comfort and flexibility of a modern garden room.
Thermal & Acoustic Performance
Each wall, floor and roof panel includes high-density insulation. This keeps you warm in winter, cool in summer and helps limit noise transfer for better focus and privacy.
Composite Cladding
Made from bonded wood-plastic or resin panels, composite cladding keeps its colour and shape with no staining or sealing needed. It’s resistant to mould, insects and rain.
All-Weather Ready
The sealed build system, moisture-proof membranes and secure window and door fittings ensure your room stays dry, secure and free of draughts or leaks.

Every unit is made in our Telford workshop. We assemble each section for a perfect fit, then deliver and install the complete room with precision and speed.

Do You Need Planning Permission for a Composite Garden Building?
In most cases, garden rooms fall under permitted development rights, meaning you won’t usually need planning consent. However, factors such as overall size, how close the building is to boundaries or the way you plan to use the space can influence whether approval is required.
As a general rule, if your structure is under 2.5 m in height and positioned within your back garden, it will typically meet permitted development guidelines. Larger footprints, business-use studios or buildings installed in conservation areas may still require planning checks, so it’s worth confirming the details with your local authority.
We’ve put together a clear guide outlining the key requirements, exemptions and how to ensure your project stays compliant.
