Single-storey extensions in Brierley Hill

Before your single-storey extension in Brierley Hill

Planning applications and lawful development certificates for Brierley Hill go to Dudley Council. Many single-storey extensions fall under permitted development, but not every house keeps those rights — conditions on newer estates, conservation areas and Article 4 directions can remove them. The structural work also needs Building Regulations approval, through the council's building control team or a registered building control approver.

If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.
Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.
Detached houses get a little more room: 4 metres as standard, or up to 8 metres with prior approval.

Which options suit homes in Brierley Hill?

Wrap-around extension

Combines a side and rear extension into an L shape, giving the largest ground-floor gain. Because it extends both sideways and rearwards, a wrap-around normally needs a householder planning application rather than relying on permitted development. Expect more steelwork and a more involved roof where the two sections meet.

Flat roof or pitched roof

Flat roofs, usually GRP fibreglass or EPDM rubber, keep the height down near boundaries and suit roof lanterns. Pitched or lean-to roofs with tiles to match the house look more traditional and shed rain faster, but need more height. The choice affects permitted development limits, cost, and how much light reaches the existing rooms.

Single-storey extensions prices in Brierley Hill

Expect to budget between £28,000 and £90,000 depending on size and specification in Brierley Hill. A 4 m × 5 m rear extension on a semi, with roof lights and bifold doors: typically £40,000–£52,000.

Questions about single-storey extensions in Brierley Hill

Which postcodes in Brierley Hill do you work in?

We cover DY5 and the streets around them. If you're on the edge of Brierley Hill, neighbouring Netherton and Lye are covered too.

How long does a single-storey extension take?

Allow 8–12 weeks on site for most single-storey extensions, plus time beforehand for drawings and approvals. If you need a planning application or a lawful development certificate, councils aim to decide within 8 weeks. Glazing and steel are ordered early so they arrive when the shell is ready, which keeps the build from stalling halfway.

Who approves single-storey extensions in Brierley Hill?

Usually building control, and sometimes planning. Dudley Council is the planning authority for Brierley Hill; Building Regulations approval comes from its building control team or a registered building control approver. We'll tell you which applies after the survey.
