Single-storey extensions in Redditch

Before your single-storey extension in Redditch

Before work starts on your single-storey extension in Redditch, two things get checked: whether planning permission from Redditch Borough Council is needed, and how Building Regulations approval will be obtained. If you share a wall with a neighbour, the Party Wall etc. Act 1996 may apply as well.

Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.
Under permitted development, a rear extension on a semi or terrace can usually project 3 metres from the original back wall, or 6 metres through the prior approval route.
A lawful development certificate from Redditch Borough Council confirms in writing that a permitted development extension is lawful, which helps when you sell.

Which options suit homes in Redditch?

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.

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.

What does your single-storey extension cost in Redditch?

Before you book in Redditch

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.

Building control's completion certificate confirms the work met Building Regulations when inspected.

Does Redditch Borough Council need to approve my single-storey extension?
