FAQ

Are your garden rooms insulated for year-round use?

Yes — every room is fully insulated with high-performance materials (Celotex, Kingspan, or Knauf), PIR foam boards, and breathable membranes. Double air-vented wall cavities prevent condensation, ensuring a comfortable temperature all year while helping reduce energy bills.

Do your garden rooms require planning permission?

In most cases, our garden rooms do not require planning permission due to their construction methods. However, certain circumstances may require it.

How long does the installation take?

Most garden rooms are installed in just a few days, thanks to our pre-manufactured steel frame system and ground screw foundations. There’s no waiting for concrete to cure, which speeds up the entire process.

What sizes and layouts are available?

We offer three luxury ranges — Cumulus, Stratus, and Cirrus — but every garden room is bespoke. You can customise dimensions, layouts, and finishes.

What type of foundations do you use for garden rooms?

We use an eco-friendly ground screw foundation system — no digging or concrete required. This makes installation quicker, cleaner, and suitable for uneven terrain or areas with poor drainage. The system is fully removable, recyclable, and avoids the cracking or subsidence issues sometimes caused by concrete.

What cladding options are available?

You can choose from composite wood or natural timber cladding. Both come with breathable membranes and OSB structural layers for strength. Maintenance-free options are available, providing a stylish, fade-resistant, and weatherproof finish with minimal upkeep.

Do garden rooms come with electricity?

Yes — all rooms include a plug & play electrical package with internal lighting and external wall lights. Optional upgrades include smart lighting, additional sockets, and data points for internet or entertainment. Wiring is safe, compliant, and discreetly concealed.

Are your garden rooms environmentally friendly?

Yes — our construction avoids concrete waste and timber offcuts. We use recyclable steel frames and screw systems, reducing environmental impact and keeping sites clean with minimal ground disruption.
