NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement conversion and construction in West London W/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.

Each dig begins with what lies underneath. We look at the soil, the ground water and the neighbours’ foundations first.

The walls go in before the dig, as piles or underpinning bays. Raking props hold them while the soil comes out.

A slab is cast on its reinforcement, then the box is waterproofed. Only then do floors, services and joinery follow.

In Fulham we built four houses with basements around a courtyard. Under a Chelsea townhouse, a new lower floor now holds a gym.
