NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement golf simulator rooms in Belgravia SW1, 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.

Belgravia houses are tall, formal and uniform. A private tee bay suits the floor below the reception rooms, out of view.

Westminster allows one storey below the lowest original floor. The March 2024 neighbourhood plan would rather rooms rise than sink. Mews houses get the coldest welcome. For golf there, we advise early.

Groundwater is the hazard here. Floods in July 2021 taught the area a lesson. The bay floor is tanked to BS 8102 Grade 3, drained and pumped. Launch monitor and projector stay well above any water risk.

We built a gym under a Chelsea townhouse, across its full footprint. It is not a golf room. It shows how we handle height, plant and finishes for a private leisure floor.
