Drag at least one piece of planning furniture into the room above to confirm your size, then continue to finishes.
Doors & glazing
Pick your primary door system. Add windows below if you need more light.
Exterior finish
Pick one finish for the whole building. The right choice for most rooms.
Want a different finish on each face? Open this and choose per elevation. Money-saving tip: put your premium cladding on the elevations you’ll see every day — and drop back to Standard Redwood on the faces that sit against a fence, hedge or boundary wall. You get the look you love on the walls that matter and keep the build cost sensible.
Optional outdoor add-ons that wrap your garden room. Decking and pergolas are sized in proportion to your building footprint — final layout finalised on your survey.
Interior finish
The character of the room from the inside.
Flooring
Three tiers laid over a fully insulated subfloor.

Standard first-fix electrics are included on every build. Add extra fixtures below — priced identically to the 3D configurator.

- Track rail with adjustable spotlights
- 4 × 13 A double sockets
- Electric panel heater
Optional extras
Light touches and bigger upgrades. Each one updates the price live.
