NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle loft conversions, dormers and mansards in Hampstead NW3, under one contract. A main dormer loft typically runs £90k to £140k. A mansard loft runs £140k to £220k. Call 020 7731 6841, and a budget estimate typically follows within seven days.

Hampstead’s Georgian and Victorian houses climb the hill. Many look out over the heath.

Family houses outnumber flats here, so a loft is a common wish.

The village has been a conservation area since January 1968. Roof permitted development falls away inside it.

The Hampstead plan’s Policy DH1 keeps extensions subservient. New dormers should be modest, set back, and ideally at the rear.

Many houses are listed. Then Camden’s listed consent applies, even where planning would not.

A sloping Hampstead site can complicate scaffold and access.

The guide figure is a project total.

Fees, party wall costs, contingency and VAT sit outside it.

How far back must a Hampstead dormer sit from the eaves?

Policy DH1 asks for dormers to be set back, without fixing a figure.

We draw it so the original roof slope stays readable.

Is a front dormer ever accepted in Hampstead?

The Hampstead plan prefers the rear slope.

A front dormer would need a strong local precedent.

We look at the street before suggesting one.

Does a listed Hampstead house need consent for loft insulation?

It can, where the work touches historic roof fabric.

Listed consent is needed even where planning is not.

We agree the approach with Camden first.

Can a Hampstead house with heath views take a bigger roof extension?

Views do not earn more volume. Policy DH1 keeps additions subservient.

Visible roofs are watched more closely, not less.
