The East London-based practices project will sensitively and sustainably restore the original 34 Belsize Lane building in Belsize Park. It will also add a lightweight first-floor addition above its bedroom wing.The house was designed and built between 1975 and 1976as a home and studio for herself and her family by Wolton, who died four years ago, aged 87.In 2023 it became her first building to be included on the National Heritage List for England, after being given statutory protection by the Department for Culture, Media and Sport on the advice of Historic England.AdvertisementWolton (ne Cheesman) formed the architectural firm Team 4 in 1963 with Richard Rogers, whom she had met while studying at Epsom, along with Su Rogers, Norman Foster and her younger sister, Wendy Cheesman (who later married Foster). She left the practice a few months later.The 34 Belsize Lane home adopted some of the key concepts of design developed during her career, including notions regarding the principles of light, the arrangement of spaces and their connection to the landscape.It is built around three courtyard gardens and features a series of rooflights, bespoke sliding timber shutters and conservatory-like antechambers areas Wolton called pause spaces, separating the living and working parts of the house.As a Modernist, she was interested in the quality of architecture that came through simple construction and an expression of how things came together. Extensions and additions were seen as lightweight elements that contrasted with the heavier elements of primary walls.At the time of its listing, Historic England regional director Tom Foxall described the house as an accomplished piece of her work, adding: Wolton's buildings are little known, but she made an important contribution to post-war Modernism in England.AdvertisementThe building is a meticulously conceived studio house which creatively integrates into its setting and meets the high threshold for listing.The house has been empty since her death and will become a family home after the restoration.The first-floor extension is set to be made of a lightweight timber structure, which a statement from EBBA said reflects the language of construction found in the work of Georgie Woltons oeuvre.Other works include reconstruction of some external walls to increase insulation and address structural issues.In August last year Camden Council also approved measures to redevelop the propertys garden, install solar panels, an air source heat pump and rainwater harvesting measures.EBBA founder Benni Allan said: With this project, we intend to demonstrate new strategies for the restoration of Modernist houses, creating a sustainable model to restore and retain these architectural icons whilst pioneering a new future for them.Critic and author Jonathan Meades has described Wolton as the outstanding woman architect of the generation before Zaha [Hadid].Wolton had a longstanding interest in buildings designed to function as both domestic and work spaces. Her best-known work is Phase I (1969) and II (1971-2) of Cliff Road Studios.Her now-demolished Fieldhouse in East Horsley, Surrey, was built in 1968 with a Cor-ten steel frame. It was among the first domestic uses of Cor-ten steel in the UK and was one of several of houses designed by British architects in the 1960s and 70s that were heavily influenced by Mies van der Rohes Farnsworth House in Illinois.
