NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement gyms and spa rooms in Weybridge KT13, 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.
A Weybridge gym is usually asked to do a lot. Free weights, a cardio line and a studio floor all want space. Wide plots make a generous basement plan possible.
Elmbridge sets no depth limit for basements. That helps, because a gym needs clear height for overhead lifts. Outside the Green Belt, design, neighbours and drainage are the tests. DM6 tree protection applies throughout.
Mature trees often stand in large gardens. Roots set how close the dig can go. The floor is reinforced or isolated for dropped weights. Fresh air and cooling keep a hard session comfortable.
Our built gym is in Chelsea. It has mirrored walls, a spin bike and a rowing machine. Our work is in London. One team designs, prices and builds it.
