Contemporary Rear & Side Extension — Black Timber Clad Addition to Victorian Terrace, Conservation Area This bold and carefully considered extension in Camberwell, Southwark demonstrates MTA's ability to design a striking contemporary addition that enhances rather than conflicts with its Victorian context. MTA won planning permission from Southwark Council to replace the existing sloped roof rear addition with a black timber clad cube — a monochrome contemporary insertion that contrasts confidently against the period property while complementing the neighbouring black slate roofs and the existing rhythm of window openings. Working closely with the clients to develop a raw, essential design using a monochrome palette of natural materials, MTA created an interior where the elegantly detailed exterior black timber cladding contrasts with a white interior and polished concrete floor. The raw palette is enriched by the traditional London brick flank wall extending inside, enhancing the historic character of the property while anchoring the new extension to its setting. The dining area is positioned under a long structural glass rooflight and centred on a black-framed pivoting door to the garden, creating a dynamic visual axis through the extension into the garden beyond. Linear slot openings with flush frameless windows frame views of surrounding trees. A side extension with cantilevered canopy in the same black timber cladding completes the exterior. The island kitchen is designed with a minimal white aesthetic and stainless steel splashback, while the upstairs study features built-in oak joinery and a large square window framing the rear garden.
