01 / A CLOSER LOOK
The project layout
The 8 m × 3.3 m building combines a finished main room with a storage compartment approximately 1.5 m wide. The storage area uses an OSB finish, while the main room has plasterboard, skimmed walls, white Dulux vinyl matt paint, MDF skirting and laminate flooring.
02 / A CLOSER LOOK
A clean cedar frontage
Western Red Cedar with concealed fixings gives the front its continuous finish. A hidden storage door keeps the practical compartment discreet. The side and rear elevations use cement particle boards with an anthracite rendered finish. Boundary and fire requirements must be assessed for each site.

Roof, glazing and climate control
A 400 mm front canopy, EPDM roof covering, rear gutter and composite front step complete the exterior details. The PVC French doors measure 1600 × 2030 mm, accompanied by two 800 × 2030 mm fixed glazed panels with anthracite external finishes. An LG air-conditioning unit with smart internet control serves the main room.

Lighting and services
The recorded installation includes eight internal LED lights, five double sockets, four external LEDs, a consumer unit and a storage-room light. SIP construction is used for the base, walls and roof, with foundations selected for the project conditions.
