Shoehorned into the back of a beautiful Edwardian terraced property, the existing studio was entirely unloved and underwhelming. Every inch of wall was stained orange by cigarette smoke, the single glazing was falling out of its rotten frames and the whole place was uninsulated. This resulted in high levels of damp and extreme black mould. However, there was opportunity in this property, which lay in its ‘good bones’ and the abundant, overgrown private garden.
From the outset, the extension was viewed as a single piece of cabinetry crafted out of a single material – Canadian Douglas fir. The very highest levels of carpentry were achieved with the extension being entirely prefabricated and erected in workshop conditions by a team of highly skilled carpenters in Devon. The extension structure, along with all the doors and windows, was then disassembled, transported, craned-in and erected on site within a matter of days. This was also vital when working through the pandemic in 2020. The ambitious scheme increases the footprint by 50% to provide a separate bedroom with the ability to create a second bedroom for family growth. The new bedroom is nestled within the lush planting seen through a vast picture window and secluded bench seat. The Douglas fir ceiling with its exposed beams make this sleeping area very restful, a feeling which is amplified when it rains and the light drumming is heard on the roof as though in a tent. The built-in wardrobe which serves the bedroom also acts as a division between the bedroom and the dining room.
Flooding through each room and down each step is a tactile concrete floor which, like a frozen lake, curls and ripples with character. Polishing the screed removes the need for additional floor finishes and was required in either case given the ground conditions. All radiators have been removed in lieu of zoned underfloor heating encased in the concrete screed which acts as a heat sink. The vertical faces of the steps reveal the casting process and is speckled with air holes. Beside the steps leading into the sunken extension is a smooth concrete column, encasing the steels which support the structure above.
The grand proportions of the 3.5m tall window and door in the living space now look onto the extension and the sheltered courtyard. The concrete inside flows outside too, where it forms the upstand of the timber extension, paving slabs and the wall of the planter on the opposite side. Shade has been embraced here. Lush ferns and feature acer trees offer a tranquil, changeable picture to look onto from inside, appreciated at night with discrete up-lighting.
Utilising every bit of space, the garden acts as another room, particularly in summer. The shady courtyard-like space by the extension offers respite from the summer heat, whilst generous seating at the end of the garden basks in it. Garden storage is hidden in a purpose built Douglas fir bench and barbecue station. Rainfall is captured from the new extension and redirected to the garden via perforated drains and a soakaway to meet the watering needs of the plants. The garden has been levelled and landscaped, with a careful balance between wildlife and socialising at its heart. Hints of the old property can still be seen from the outside, including the arch of the old back doors, retained to match the rest of the terrace. Even three metal water tanks which were dug up during the extension excavations (done by the clients during the first lockdown in 2020) have been lovingly repurposed as seating and planters in the garden; a nod to the history of the house.
