Pimlico stucco houses are mostly flats now. A pool needs a whole house, and we say plainly when it fits.

A Pimlico pool needs the whole house.

SW1V: White stucco terraces on garden squares
Policy 50: One storey below the lowest original floor
Near the river: Flood risk is checked first

NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement swimming pools in Pimlico SW1V, 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.

Pimlico was laid out as one estate, in the same era as Belgravia. Its white stucco terraces face garden squares. Most are now split into flats. A pool needs the whole building, held as one.

For a whole house, Policy 50 allows one storey below the lowest original floor. The tank and its plant room share that storey. Since July 2016, basement work needs planning across Westminster.

The river is close, so flood risk is checked first. Flood zones 2 and 3 need a site specific assessment. The pool tank is designed against uplift, with sumps and a standby pump.

We built a marble lined pool in a Knightsbridge townhouse. Just north of Pimlico, we refurbished a Belgravia apartment in full. One team designs, prices and builds the pool.
