A Victorian chapel in The Bromptons, which has stood empty for 30 years, is up for sale – and it comes with plans to turn it into a deluxe £25m home. St Luke’s Chapel was built in 1850 to serve the Brompton Hospital (which was turned into a series of luxury apartments by Northacre in 1997) but has been unused since 1991. Now, the Grade II listed building is being sold for £7.5m, and it comes with the opportunity to transform it into a unique five-bedroom residence.

The Royal Borough of Kensington & Chelsea has given approval to expand the chapel’s current footprint from 4,257 sq ft to 7,330 sq ft, having previously turned down two applications for planning permission. The development is expected to cost around £5m, including £3.15m for development and £1.1m for a one-off service charge to nearby residents, to compensate for what could be a year of disruption.

The cherry on the cake is the neighbouring Northacre development’s five-star suite of amenities, which the new buyer would have access to – including porterage, a residents’ gym and swimming pool, a board room and on-site security.

When complete, it is estimated the property will be worth around £25m – a conclusion drawn from similar developments in King’s Chapel Chelsea, which saw two residences offered for £20-£25m, and St Saviour’s in Knightsbridge, a single dwelling that sold for £45m.
