Flat Refurbishment in Belsize Park.
Refurbishing a flat is a different job from refurbishing a house. The design questions are the same, but the approvals, the logistics and the neighbours are not. In Belsize Park most flats sit in mansion blocks or converted houses, which means a freeholder or managing agent to satisfy, restricted working hours, lift and stair access to plan, and sound insulation between floors to prove at inspection.
We handle all of it. Before work starts we prepare the drawings and method statements the freeholder needs for a licence to alter, agree deliveries and hours with the building, and protect the common parts. On site, our own team does the strip-out, services, joinery, kitchen, bathrooms and decoration, so the flat is closed up and finished in one continuous programme.
Because we supply the Italian and German kitchens and the bathroom furniture ourselves, we can design the whole flat as one scheme and order everything at once, which matters when access is difficult and every delivery has to be booked.

Belsize Park: the houses and the planning rules.
Belsize Park was laid out in the 1850s as a suburb of paired stucco villas with generous gardens, between Hampstead to the north and Primrose Hill to the south. The villas survive in long, leafy streets, many divided into flats, alongside Edwardian mansion blocks and post-war infill.
It is one of the most active refurbishment markets in north London: reuniting houses that were split into flats, refurbishing garden and first-floor maisonettes, and adding rear extensions and basements beneath the villas. Camden's Belsize guidance shapes what is possible on each street.
The Belsize Conservation Area covers most of the district.
London Borough of Camden
Camden decides applications. The Belsize Conservation Area statement sets out expectations for rear extensions, roof works and stucco repair, and Article 4 directions apply on many streets.
Flats and maisonettes
Most properties are leasehold flats, so a licence to alter from the freeholder sits alongside planning and building control.
Basements
Camden's basement policy applies, with a Basement Impact Assessment for any new lower ground floor.
Approvals for flat refurbishment in Belsize Park.
Flats need a licence to alter from the freeholder or managing agent as well as building regulations approval; the sound insulation between flats is checked at inspection, and any change to the exterior, including windows, needs planning permission.

Flat Refurbishment in Belsize Park: your questions.
Do I need the freeholder's permission to refurbish a flat in Belsize Park?
Almost always, through a licence to alter. We prepare the drawings and method statements the freeholder or managing agent asks for and build their approval time into the programme so it does not hold up the start.
How long does a flat refurbishment take?
A two-bedroom flat typically takes eight to twelve weeks on site once approvals are in place. Lift access, parking and the block's working hours all affect the programme, so we plan around them from the outset.
Which parts of Belsize Park do you cover?
All of Belsize Park and NW3, including Belsize Park Gardens, Lambolle Road, Glenilla Road, Belsize Avenue, Eton Avenue, Haverstock Hill, and the neighbouring districts. We are based in London and our teams work across central, north, north-west, west and south-west London.
