Basement cinema rooms in Hampstead.

Hampstead ground holds water, and Camden asks hard questions. The cinema waits for the ground report, then follows it.
A Hampstead cinema, shaped by the ground.
- Ground report first
- The design waits for the soil and water data.
- Audited assessment
- Camden has the impact assessment checked independently.
- One team
- NU designs, prices and builds.
NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement cinema rooms in Hampstead NW3, 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.
Hampstead is hillside streets, big Victorian villas and steep gardens. Many houses are cut into a slope. The lower floor may open to the garden. A cinema there is out of sight and out of earshot.
Camden allows one storey only, and never under an existing basement. A Basement Impact Assessment, independently audited, goes in with the application. The Hampstead plan adds tests on groundwater and trees. So the cinema layout waits for the ground report.
Hampstead ground holds water, and a cinema needs a dry, still room. Waterproofing follows BS 8102 Grade 3, the grade for habitable space. A drained cavity and a pump back it up. Sound lining goes on once the walls are dry.
We built basements under Fulham houses, with media rooms and snugs. In Knightsbridge we built a townhouse with a pool and a wine room. One team designs, prices and builds the work, from ground report to final tuning.

It covers the whole basement, cinema included.
