Kitchen extensions in Sydenham

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 Sydenham start with the house, the address and the way you cook.

Start with the kitchen

Kitchen extensions in Sydenham: where to start

Sydenham's semis and longer gardens give more room than a tight terrace, which makes it tempting to build as far as the rules allow.

Test the brief against the kitchen first.

Decide where the sink, cooker and table go, and how much glass the room can take before it overheats.

The right depth is the one the plan needs, not the maximum.

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 Sydenham

Sydenham is split between Lewisham and Bromley, and the same drawing can get a different answer on either side of a road.

Outside a conservation area, a deeper single-storey rear extension can use the prior approval route.

The council consults the neighbours first.

In a conservation area, or for a flat, that route is not available.

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

Sydenham is divided between Lewisham and Bromley, two planning authorities with different local policies.

The same drawing can get a different answer on either side of a road.

Parts of the area are conservation areas as well.

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 Sydenham.

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.
