01 / THE BRIEF
A room for family life.
Set within the garden.
The brief was for a separate garden room, used as a playroom, with enough clear floor space for changing family activities. The long, open layout avoids internal partitions, with a rooflight bringing daylight into the middle of the room.
The new building sits beside a separate garden building. Its position and glazing create a corner facing the deck, with views across the lawn and a stepped outdoor approach.
The revised specification increased the room to 8.32 m × 4.07 m and included underfloor heating, a glazed rooflight and a grey exterior to suit the existing setting. The finished photographs show the light interior, large openings and canopy lighting.
02 / ORIGINAL FLOOR PLAN
One open playroom.
Two generous openings.
The original layout shows the new room at 8.32 m × 4.07 m externally, with internal dimensions labelled 8.0 m × 3.75 m. Bifold doors open at the end of the room, while sliding doors provide access from the adjoining side.
Relationship to the garden
The separate building alongside is shown at 6.0 m × 5.0 m, with a 100 mm gap indicated between the buildings. Its footprint is separate from the new playroom dimensions.
03 / SPECIFICATION & DETAILS
Light above.
Glazing around the corner.
The glazing is the defining feature: a wide bifold entrance meets a sliding-door elevation, framed by anthracite aluminium and a projecting canopy.
Inside, white walls and ceiling, recessed lights and a pale laminate floor keep the playroom bright. The rooflight brings daylight into the centre of the long room.
Foundations and structure
The revised quotation specifies SIP walls and roof on screw-pile foundations. The base uses 8 × 2 timber joists, Jablite insulation and tongue-and-groove flooring, arranged to accommodate the existing floor level and profile.
Roof and canopy
An EPDM membrane covers the roof, with black guttering at the rear. A 400 mm canopy projects above the glazed openings, and the revised design includes a 1.0 m × 1.5 m glazed rooflight.
Aluminium glazing
The specified openings are a 2,700 mm × 2,200 mm sliding door and a 3,680 mm × 2,200 mm bifold door, both in anthracite RAL 7016.
Exterior finishes
The back and sides use rendered cement-particle board in anthracite grey. The revised frontage specification calls for a clad and painted grey finish to match the existing setting.
Interior and heating
Plasterboard, skimming and white matt decoration finish the walls and ceiling, with MDF skirting and laminate flooring. Underfloor heating is specified in the revised quotation.
Lighting and power
The electrical specification includes 15 internal LED downlights, six double sockets, six external canopy lights and a consumer unit. The outside lights were to connect to the existing Lutron lighting system.
04 / THE FINISHED PLAYROOM
Open the doors.
Make room for play.
The finished photograph collection shows the room before play equipment and furniture were added, making the open layout and garden connection easy to see.
01 · OPEN INTERIOR
Clear space to use
The long room has a continuous pale floor, white walls, recessed lighting and a wall-mounted screen, with no internal partitions interrupting the main space.
02 · WIDE ACCESS
A full opening to the deck
The folded doors reveal the broad entrance, with the canopy and its lighting above. Sliding glazing gives a second connection to the outdoor space.
03 · GARDEN SETTING
Linked to the landscape
The stepped deck leads through the garden to the playroom. Mature trees, planting and the neighbouring building frame the finished outdoor setting.
