NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement swimming pools in South West London SW, 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.

A basement pool is the deepest room a house can hold. Kensington and Chelsea’s 2016 Basements SPD allows a little extra depth for it. That depth carries the tank and its structure.

The water is only part of the job. Filtration, heating and dehumidification need their own plant room. Without good air handling, condensation reaches every wall.

We built a pool two floors below the street in Kensington. Lights run along both walls of the pool hall.

Fulham pools fall under Hammersmith and Fulham’s rules instead. Belgravia pools fall under Westminster’s. We draw each pool to its own council.

Where Kensington and Chelsea allows a pool.

Council: Royal Borough of Kensington and Chelsea for Chelsea and South Kensington. Hammersmith and Fulham for Fulham.
Policy CD11: Adopted as CL7 in January 2015, kept in the 2024 Local Plan. One storey, under half the garden.
Basements SPD: Adopted April 2016. The storey cannot be split in two later. A pool may earn a little extra depth.
The garden: The garden left over must stay as one area.
Plant: A plant room holds filtration, heating and air handling for the pool.
Dehumidification: The pool hall needs its own air handling to control moisture.
