Building work in Kilburn: area guide

This is our area guide to building work in Kilburn (NW6, Brent and Camden): the housing, the council rules that apply (Brent Council or Camden Council for planning) and every service we offer here. For whole-house refurbishment go to Home renovation in Kilburn.

Most homes in Kilburn are flats, 92% on VOA figures and many of them in post-war blocks, and that decides which job you have before anything else does. The red brick blocks off the High Road were flats from the day they were finished, with solid masonry cross walls, timber floors and a communal stair, while above the shops there are further flats reached by a single door squeezed between two shopfronts. In both cases you own a slice of a building rather than a building, the lease decides what may be altered, and the work has to happen without making life impossible for the people and businesses on the other side of the walls.

By the valuation list's count, Kilburn holds about 17,940 homes, 8% houses and 92% flats; by age, 48% were built before 1919, 2% between the wars and 49% since 1945.

Structural alterations inside a mansion flat start at the cross wall

It is a mistake to assume a wall in a flat is only a partition. In purpose-built blocks the masonry cross walls carry floors across the whole building, and some run right through your flat. An opening in one is load-bearing wall removal, not an open-plan conversion job: a designed beam, engineered padstones and a check on the load path down through the flats below to the foundation. We appoint the structural engineer, the freeholder's own surveyor usually reviews that design as a condition of consent, and the steel comes up the communal stair in bolted sections.

The Party Wall etc. Act 1996 applies inside blocks as well as between houses. The floor between two flats is a party structure, so cutting into it, forming an opening in a party wall or bearing a beam into one triggers notice to the owners above, below or alongside. That surprises people, and it is far better handled before work is booked than after a neighbour objects. We flag which parts of a scheme are notifiable at survey stage, and work to the hours and protection measures the lease and any party wall award set out.

Flats above the High Road shops are sized by the stair

Living space above a parade of shops brings its own constraints. Access is normally one narrow stair from the street with a tight turn at the top, which sets the maximum length of anything carried in, from a beam to a bath, so a bathroom renovation up here is planned around what fits the turn. The compartment floor between the commercial ground floor and the flats above exists for fire separation, so new pipe or cable runs through it are properly fire stopped. The business below trades during the day, which limits when the heaviest work can happen.

Kilburn High Road is a busy bus route with restricted loading and controlled parking on the streets behind it, so an unplanned delivery simply does not arrive. We arrange permits and bay suspensions ahead of time, break loads down so a small vehicle can service the job, and take waste out in bags rather than assuming a skip can stand outside a shopfront. On the quieter streets towards Kilburn Grange Park and Queen's Park the logistics ease off, while the lease questions stay exactly the same.
