Local studio Mata Architects has extended a family home in Hampstead, London, with a timber-clad building featuring a glazed corner and an overhanging roof.

Named Panoramic House, the extension was designed to sit lower than the main living space, to make better use of the space and connect the home to the garden.

Previously, the home's main living area sat 1.5 metres above the garden and was accessed via a long flight of stairs, which the clients felt disconnected it from the rest of the property.

Mature trees and sheer curtains provide privacy to the room

The position of the extension was largely determined by the mature trees on the site, with Mata Architects working alongside tree care specialists to establish root protection zones1.

"What might have been a constraint became an opportunity, resulting in an extension that feels intertwined with the landscape rather than imposed upon it", Marks said.

Large sliding glass doors meet at the corner of the extension. These offer panoramic views of the garden and can be opened to connect the room directly with the garden and terraces.

The exterior of the new building was finished with timber battens and topped with an overhanging, tapering roof that provides shade and helps reduce heat in hot weather. Underneath the roof, a mirrored surface reflects the garden.

The surrounding trees further provide natural privacy and shading.

"Combined with high-performance glazing, these elements ensure the space remains comfortable throughout the year", Marks said.

"A sheer curtain adds another layer of control and atmosphere, softening the light and transforming the space when drawn".
