An Earl’s Court pool needs a whole house that is not listed. That rules many out, and we say so.
An Earl’s Court pool, and the houses that can hold one.
- CD11
- One storey, half of each garden at most
- Listed
- No excavation beneath, vaults included
- CD10
- Outdoor plant judged for look and siting
NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement swimming pools in Earl’s Court SW5, under one contract. A new basement dig typically runs £500k to £900k. Converting an existing basement runs £180k to £300k. Call 020 7731 6841, and a budget estimate typically follows within seven days.
Earl’s Court is tall stucco terraces and red brick mansion blocks. Most were split into flats long ago. A pool needs a whole house, held as one. Those are the minority here.
Policy CD11 allows one storey, under no more than half of each garden. A pool must fit that single storey, plant included. Under a listed building, no excavation is allowed, vaults included.
A pool hall needs heat and air, and some of that plant sits outside. Outdoor units are judged under Policy CD10, for look and siting. We place them out of sight before the application. Every basement here also needs a flood risk assessment.
Our pool dig for two houses in Kensington W8 is close by. We also refurbished a terraced house in Chelsea. One team designs, prices and builds the work.
