Alison Brooks Architects鈥 contemporary extension to an 18th century farmhouse has been named as RIBA鈥檚 house of the year for 2021.

Known as the House on the Hill, the home was praised by judges for the 鈥渟eamless鈥 integration of its new angular structure with the existing house, which has also been restored.

Amin Taha, who chaired the awards, said the extension added 鈥渄epth of scale and richness of experience鈥 to the farmhouse.

He said judges were impressed by the scheme鈥檚 鈥渇ragmented form鈥 and Alison Brooks Architects鈥 鈥減rocess of subtly breaking down the rigid and spatially predictable grid with spatial inflection鈥.

The two-storey extension, which replaces a large 1970s pool house, contains a central kitchen and dining area, a double-height living room, two bedrooms, an office and a first floor terrace.

The owners, David and Jenny Clifford, have scattered pieces from their vast art collection throughout the property, including on a gallery unit fitted to the extension鈥檚 staircase.

Partially embedded into the hillside on a site overlooking the Wye Valley, the building is faced with a dark grey/brown cladding inspired by the nearby Forest of Dean.

It also boasts impressive sustainability credentials, with an extensive green roof planted with native wildflowers and power supplied by solar panels and ground and air source heat pumps.

RIBA president Simon Allford said the scheme鈥檚 geometric design 鈥渟kilfully fuses together the old with the new 鈥 connecting two architectures separated by over 300 years鈥.

He added: 鈥淚ntriguing and distinguished, House on the Hill is the impressive result of a ten-year collaboration between the homeowners and their architect. This is an extraordinary labour of love in architectural form.

鈥淓very detail has been meticulously considered and exquisitely finished, resulting in a truly remarkable home that enhances its unique setting.鈥 

Alison Brooks said the house 鈥渞eveal a new way of living in the landscape鈥.

鈥淚 see private house commissions as a rare opportunity to test new ideas in a concentrated form 鈥 they are the built equivalent of writing an essay. So, this accolade is a testament to my client鈥檚 belief in the value of architecture and their willingness to embrace the new.鈥

The Cliffords, who have been working on the project for decades, said they learned a 鈥済reat deal鈥 during the process.
