KOSMOS / RESIDENTIAL CONSTRUCTION
Garden rooms
A garden room should be considered as a complete small building. The base, weather protection, insulation, ventilation and interior details need to work together.
Plan the work as a whole.
The intended use helps determine the layout, service requirements and construction approach. Site access, boundaries, drainage and any planning or building-control requirements need project-specific review.
Care at every interface.
Our documented work includes timber framing, insulation and vapour-control layers, roof edges, cladding and interior fit-out. These construction details are shown separately so the enclosure is visible before it is covered.



Questions before you build.
Can a garden room be used all year?
Comfort depends on the specification, insulation, glazing, ventilation and heating. Agree the intended use and suitable design rather than assuming every garden building performs the same way.
Does a garden room need permission?
Requirements depend on size, height, location, use and property restrictions. The proposal should be checked before construction is agreed.
