Kitchen extensions in Honor Oak
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 Honor Oak start with the house, the address and the way you cook.

Kitchen extensions in Honor Oak: where to start
Honor Oak's steep streets mean many gardens sit above or below the kitchen floor.
A rear extension can sort out the levels with a proper threshold, but the decision has to be made before the foundations are drawn.
Think about the view up or down the garden as well as the light.
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 Honor Oak
The Southwark–Lewisham boundary runs through Honor Oak, so the first check is which council covers the address.
On sloping ground a rear extension can need retaining walls and deeper foundations.
That brings in the Party Wall Act when they are close to a neighbour's.
A converted flat has no permitted development rights for an extension.
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
Honor Oak is split between Lewisham and Southwark, and the boundary runs through the middle of it.
Which council you apply to, and which policies apply, depends on your street.
That is the first thing to establish, not the last.
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 Honor Oak.
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.
