Basement cinema rooms in Chelsea.
Chelsea · SW3 · Chelsea townhouse, full refurbishmentCompleted work, photograph
A Chelsea cinema belongs below ground, away from the street and the neighbours. We design the room, its sound and its equipment as one job.
What a Chelsea cinema has to solve.
- Room within a room
- The walls and ceiling stand clear of the house structure.
- Hidden rack
- The equipment sits apart, so the cinema stays quiet.
- One team
- NU designs, prices and builds the whole room.
NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement cinema 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. Many already have a cellar or a low lower floor. A cinema suits that space, since it wants no daylight. It can take a floor that once held storage.
The council allows one storey under no more than half the garden. So the cinema must earn its place within that single floor. The room, its sound build up and the ducts above share the ceiling height. We draw the section before we draw the plan.
A good cinema is a room within a room. Its walls and ceiling stand clear of the structure, on isolating mounts. Bass is the hard part, so the floor is treated too. Air arrives slowly through lined ducts.
In Chelsea we refurbished a townhouse in full, and it includes a cinema room. We also fitted a deep green media room in a Chelsea terraced house. One team designs, prices and builds the room, and runs the whole contract.

Further reading, from the journal
Can a Chelsea townhouse basement take a private cinema?
Yes, if the floor keeps enough clear height after the sound build up.
We check the section first. The one storey limit then shapes the room.
How is a Chelsea basement cinema kept quiet for the neighbours?
We build a second shell inside the first. The house then carries none of the sound.
Mounts, dense boards and a floating floor all help.
What does a home cinema cost in a Chelsea basement?
Our basement band is £450 to £780 a sq ft, construction only.
Fees, VAT and contingency sit outside that rate.
Where does the equipment go in a Chelsea cinema room?
It goes in a rack cupboard or small room beside the cinema.
That room has its own cooling. Cables run through to the seats and screen.
Does a Chelsea cinema room need its own planning permission?
The basement does, since every basement in the borough needs planning.
The fit out inside an approved basement is designed alongside it.
