Single-storey extensions in Smethwick

Covering Smethwick

Smethwick sits 3 miles west of Birmingham, with West Bromwich 2 miles to the north-west and Birmingham 3 miles to the east.

Homes in the West Midlands

The West Midlands has a large stock of 1930s semis and Victorian terraces in red brick, so matching brick and roof tiles is often the key to an extension that looks original.

What do you get with a single-storey extension?

We design the extension around how you use the house: where the light comes from, how the new room joins the old one, and what happens to the drains and the garden. The structure is built in brick or block to match the house, finished with a flat roof and lantern or a pitched roof, then insulated, plastered and handed back ready to decorate.

Do you need permission for a single-storey extension in Smethwick?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

In England a single-storey rear extension can often go ahead under permitted development: up to 3 m deep on an attached house or 4 m on a detached one, no higher than 4 m, with eaves no higher than 3 m within 2 m of a boundary. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.

What can affect a single-storey extension?

Drains under the footprint may need diverting or a build-over agreement with the water company.
Kitchens and doors have long lead times, so we order them early.
