House Extensions in Woolwich

House extensions in Woolwich, Plumstead and Charlton. Rear, side-return and wrap-around builds: drawings, Building Control, structure and finish, one team throughout.

Good to know

House Extensions: the questions

Do I need planning permission for a rear extension?

Often not - many rear extensions fall under permitted development, and most side returns on a terrace do too. But permitted development has real limits on depth and height, and the borough has its own quirks. We check before you commit to a design.

What about the neighbours?

On a terrace or semi you will almost certainly need to serve a party wall notice, and that has a statutory timetable. Start it early. It is the single most common reason an extension starts later than the owner expected.

How long does an extension take?

A single-storey rear or side return is typically twelve to sixteen weeks on site, plus the design and approvals before it. Anyone quoting six weeks is quoting the shell, not the finished room.

Does an extension need Building Control even without planning permission?

Yes. Permitted development only covers planning. Building Regulations still apply to the foundations, structure, insulation and drainage, and the work has to be inspected and signed off.

Can I live in the house during an extension?

Usually, yes. Most of the work happens outside until the final stage, when the new room is opened into the existing house. That part is planned so the kitchen is out of action for as short a time as possible.

The Victorian terraces through Plumstead and Woolwich were built with a narrow side return that does almost nothing, and filling it in is the change that transforms the ground floor of that kind of house. It is also structural work next to a party wall, which is where the process matters as much as the building.

In the Plumstead and Charlton terraces most extensions are side returns, filling the narrow strip beside the back addition to make a wider kitchen. The boundary wall, the neighbour's drainage and the steel over the new opening all have to be worked out before anything is dug.

What's involved

House Extensions in Woolwich: the job, explained

01

Side returns and rear extensions

The classic terrace job. Steel over the opening, the kitchen moved into the new space, and light brought into a room that never had any.

02

Drawings and Building Control

Structural calculations, the notice, the inspections and the sign-off, handled rather than handed to you.

03

Party wall matters

On a Woolwich terrace there is nearly always a party wall notice to serve. We tell you early, because it takes time and it is not something to discover late.

04

One team to the finish

Groundwork through to plastering and second fix, so nobody is blaming the last trade.

05

Drainage found before digging

A drain survey where needed, so a shared sewer under the side return is known about early and built over with the right approval.
