Basement cinema rooms in South West London.
Chelsea · SW3 · Chelsea terraced houseCase study
A dark, quiet room for films and sport, below the house. We build the shell, the sound isolation and the cooling together.
Why the basement suits a cinema.
- No daylight
- Which a cinema actually wants
- Rack room
- Amplifiers kept apart from the seats
- Quiet air
- Cooling that never drowns the dialogue
NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement cinema rooms in South West London 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.
A cinema needs darkness and quiet. A basement gives both without blackout blinds. The traffic of the SW postcodes stays above.
Sound must also stay in. Walls and ceilings are built as a room within the room. Doors are heavy and sealed.
Screens, projectors and amplifiers give off steady heat. The amplifiers sit in a ventilated rack room, apart from the seats. Cooling is ducted slowly so it stays silent.
We have built media rooms in Chelsea, Fulham and Belgravia. Each was finished to suit the house above.

Further reading, from the blog
Does a basement cinema need extra soundproofing?
Yes, to keep sound inside the room.
Walls and ceiling are isolated from the house structure.
Where do the amplifiers go?
In a ventilated rack room beside the cinema.
Their heat and fan noise stay away from the seats.
Can a cinema share the basement with a gym?
Yes, if the one storey has room for both.
Sound isolation keeps them from disturbing each other.
Can a cinema go into an existing SW cellar?
Often, if the height allows after lowering and waterproofing.
That route usually costs less than a new dig.
