Primrose Hill basements under small terraces. Camden tests them hard, and the fronts are watched closely.

- June 2017
- Camden removed basement permitted development
- Burland 1
- Camden’s cap on damage next door
- Short fronts
- Little room for a light well
NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement conversion and construction in Primrose Hill NW1, 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.
Primrose Hill houses are smaller Victorian terraces facing the park. Front gardens are short.
That leaves little room for a front light well. A 1983 Article 4 direction also controls front walls and hard standings.
Since June 2017, every Camden basement needs planning permission. Policy A5 allows one storey only.
Camden asks for a Basement Impact Assessment, audited independently. Damage next door is capped at Burland category 1.
With neighbours on both sides, that cap shapes the whole method. Many houses here are flats, so owners are many too.

Is there room for a front light well in Primrose Hill?
Often very little. Front gardens here are short.
On the houses Camden names, the 1983 direction controls front walls and hard standings.
Can a Primrose Hill flat owner dig a basement?
Flats have no householder permitted development rights, and Camden needs planning anyway.
The freeholder’s consent under the lease is needed too.
How does Camden protect a Primrose Hill neighbour during a dig?
Damage next door is capped at Burland category 1.
An audited impact assessment sets the method. Movement is monitored throughout.
What does a Primrose Hill basement cost?
Our 2026 cost guide puts a new dig at £500k to £900k and more.
That is a project total. The audit, fees, party wall costs and VAT are extra.
