NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle loft conversions, dormers and mansards in Primrose Hill NW1, 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.

Primrose Hill is smaller Victorian terraces, painted, with short front gardens facing the park.

A 1983 Article 4 direction controls front alterations on houses Camden lists. Its schedule includes roof changes.

So the street side is close to fixed. Any loft work looks to the rear slope.

Many houses here are split into flats. The top flat has no permitted development rights at all.

Our nearest built work is a north London house in N2.

Is my Primrose Hill house on Camden’s Article 4 list?

The 1983 direction names specific properties, not every house.

We check the schedule against your address first.

Can I add a rooflight to the front slope of a Primrose Hill terrace?

On a house in the Article 4 schedule, it would need planning.

Elsewhere in the conservation area, it is still judged closely.

Can the top flat in a Primrose Hill conversion use the roof void?

Only with the freeholder’s agreement and planning permission.

Flats lack permitted development rights entirely.

Will a Primrose Hill rear dormer be visible from the park?

Some rear roofs are seen across gardens and from higher ground.

We test sightlines before fixing the dormer’s size.
