Kitchen extensions in Brockley
Design-led: we plan the room before we price the work, so the drawing and the build match.
Build-led: our own builders, plumbers and electricians on site, one team from strip-out to finish.
We design and build extensions, from a side return to a full-width rear addition, and fit the kitchen inside them.Good kitchen extensions in Brockley start with the house, the address and the way you cook.

Start with the kitchen
Kitchen extensions in Brockley: where to start
Brockley's big Victorian houses often keep the kitchen in a narrow rear wing, with a grand room at the front that hardly gets used.
Before extending, consider whether the kitchen should move into the house rather than further into the garden.
If an extension is right, it should sit comfortably beside original detailing that is likely to stay.
We draw the kitchen layout and the new structure together.The steel, drainage and glazing are placed for the room you will use.
Sometimes a refit or an internal opening does the job without extending at all, and we will say so.
Make it buildable
House extensions and side returns in Brockley
Most of Brockley is in one of Lewisham's largest conservation areas.
A side extension needs planning permission, and the materials are looked at closely.
A great many houses here are flats or maisonettes, which have no permitted development rights for extensions at all.
For a ground-floor flat, the freeholder's consent usually matters as much as the council's.
One team handles the structure, the services, the kitchen and the finish, so nothing is left between two contractors.
The local check
What changes from one property to another
Brockley’s conservation area is one of the largest in Lewisham, and it is the single biggest factor in any job here.
Permitted development rights are restricted, and windows, doors, roofs and front gardens all come into the application.
A great many of these houses are also flats or maisonettes, where permitted development does not apply at all.
Even a modest external change needs a full application.
Much of this area is a conservation area, which removes permitted development rights that apply elsewhere.
Windows, doors, roofs and front gardens come into the application.
Each conservation area has its own appraisal of the materials the council considers appropriate.
They differ, so the answer on one street is not the answer on the next.
We check the actual address and the proposed work before saying what consent is needed.
Check the rules for your address
These are the local authority and estate sources relevant to Brockley.
The national rules
Permitted development, in plain terms
These apply across England.Conservation areas, Article 4 directions and estate covenants can tighten them, which is why the address comes first.
- A house, not a flat or maisonette, can usually add a single-storey rear extension without a planning application.The limit is 3m deep, or 4m if detached.
- The larger home extension route allows up to 6m, or 8m if detached, once the council has consulted the neighbours.It is not available in a conservation area.
- In a conservation area, an extension beyond the side wall of the house needs planning permission.That usually includes a side return.
- Every extension needs Building Regulations approval, whatever the planning route.
- Building on the boundary, working on a shared wall or digging near a neighbour's house needs notice.That is under the Party Wall etc. Act 1996.
