Two-storey rear extension in Stourbridge

We plan and build two-storey rear extensions for homeowners in Stourbridge. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. Start with a free site visit, then a written price once the design is agreed.

Stourbridge is covered from our West Midlands round, including DY5, DY8 and DY9. Two-storey rear extensions suit semi-detached houses in Stourbridge best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Stourbridge?

Whether your two-storey rear extension in Stourbridge needs a planning application depends on its size, your house and any local restrictions.

A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.

What are homes in Stourbridge like to extend?

Stourbridge has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.

FAQ

Two-storey rear extension questions in Stourbridge

Do I need planning permission for a rear extension in Stourbridge?

Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.

Do you handle building control in Stourbridge?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Can I add an en-suite upstairs?

Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.

Will I need a structural engineer?

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
