HB Devco has submitted plans for the compressive redevelopment of Hartsfield Manor in Betchworth, Surrey.
Designed by PLP Architecture, the plans seek to restore and sensitively enhance the existing manor house hotel, transforming it into a 69-key luxury hotel and spa retreat, with new facilities including an event space, hotel extension, woodland lodges and elevated treehouses.
The estate currently operates as a hotel and event venue and has also been used as a location for film and TV shows, including Apple TV+’s Slow Horses series.
Over time, the site has evolved, with later 20th-century extensions introduced to accommodate educational and training uses. The redevelopment plans will see the outdated 1970s and 1980s extensions removed with a new low-profile hotel extension set into the natural slope of the site.
The extension will provide additional guest accommodation, including a mix of standard and deluxe rooms, suites and self-catering apartments. Across the wider 16-acre site, four new lodges and five treehouses will be discreetly positioned within wooded areas.
The redevelopment will also introduce a new spa and wellness offering, including a wellness pool, gym and treatment spaces, alongside a dedicated event building for weddings and conferences, accessed directly from the manor via a weather-protected underground passage.
Ron Bakker, founding partner at PLP Architecture, said: “The Hartsfield Manor project is defined by its extraordinary setting. As one of PLP’s first rural architectural projects, we embraced the natural undulations of the site, shaping new accommodation into the hillside to maximise views and deepen guests’ connection to the landscape. Later additions that diluted the manor’s presence were removed, and the new buildings, formed from local natural materials, are rooted firmly in the land.”
Sean Quinney, director of hotel asset management at Colliers International, added: “We are delighted to have been supporting the client through the recent acquisition of Hartsfield Manor and the ongoing management of the hotel whilst working with PLP and other specialists to support the design and submission of this exciting and unique scheme.”
