NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement cinema rooms in South London SW and SE, 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.
Basements make natural cinemas, with no daylight to block out. The hard part is keeping sound in.
We build an inner shell that floats on isolators, apart from the house. The neighbour’s side of the party wall stays quiet.
Projectors and amplifiers run warm. They sit in a ventilated rack room, away from the seats.
We built a basement media room under a Fulham terrace, just across the river. Its joinery and lighting were drawn with the shell.
