THE PROJECT
From an idea
to a real space.
A 6.2 × 3.4 m SIP garden office in Hayes, with a separate storage room, generous glazing and LG heating and cooling.
TRJ Construction built this bespoke garden office in Hayes to provide a bright workspace away from the main house, with storage kept in a separate room.
Size and layout
The building measures 6.2 × 3.4 m externally — approximately 21 m² overall. An internal partition creates a storage room approximately 1 m wide, accessed through a white four-panel internal door. These overall dimensions include the walls and storage area.
SIP structure and roof
The floor, walls and roof use structural insulated panels (SIPs). The order specified a screw-pile foundation, with 1,250 mm piles as the standard specification. The roof has an EPDM covering, black edge trims and black round guttering.
Glazing and exterior finishes
Central uPVC French doors, 1,600 mm wide × 2,030 mm high, sit alongside fixed glazing. The frames are anthracite grey outside and white inside. Composite cladding finishes the front, while the sides and rear use Magply fire-resistant boards with an anthracite grey silicone K-render finish. A membrane, battens and ventilation form part of the wall build-up.
Interior and climate control
The interior is plasterboarded, skimmed and painted white, with Howdens laminate flooring and white skirting. An LG Wi-Fi R32 air conditioning system provides heating and cooling.
Power and lighting
The electrical specification includes six double sockets, eight internal downlights, four exterior downlights and a surface-mounted LED light with its own switch in the storage room. White electrical fittings, a dedicated consumer unit with RCBO and surge protection, and an upgrade to the main house consumer unit were included in the order.
