Basement gyms in Chelsea.

NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement gyms and spa rooms in Chelsea SW3, under one contract. A basement runs £450 to £780 a sq ft, construction only. Call 020 7731 6841, and a budget estimate typically follows within seven days.

Chelsea is terraces and studio houses on quiet streets near the river. Most are family homes with little spare room above ground. A gym below frees the ground floor for living. It also keeps weights and music away from the bedrooms.

Policy CD11 allows one storey under half the garden. A gym wants more clear height than most basement rooms. So the single storey is planned from the floor up. Slab, services and ceiling must all fit inside it.

Dropped plates and heavy racks need a tough floor. We build a reinforced slab with a resilient layer under the rubber. Mirrors go on flat, dry walls. Lights are set so no one lifts into a glare.

We fitted a gym in the basement of a Chelsea townhouse. The basement runs under the full footprint of the house. One team designs, prices and builds the room.
