Single-storey extensions in Kingswinford

Before your single-storey extension in Kingswinford

In Kingswinford, Dudley Council decides planning questions. We check permitted development limits and any local restrictions at the survey, then deal with the Building Regulations side so you receive a completion certificate when the work is signed off.

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.
Most of the build happens outside, so the kitchen is usually only out of action for one to three weeks near the end.

Options to consider in Kingswinford

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.

Utility, WC or boot-room extension

A smaller extension of 6–12 m² can take the washing machine, coats and a downstairs toilet out of the kitchen. Adding a WC means a new waste connection, so the position of the existing drains often decides the layout. It's a cost-effective way to free up the main rooms without a large build.

Questions about single-storey extensions in Kingswinford

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.

Which postcodes in Kingswinford do you work in?

We cover DY6 and the streets around them. If you're on the edge of Kingswinford, neighbouring Wordsley and Brierley Hill are covered too.

What should I prepare before the survey?

Think about how you want to use the new space, and gather anything you have about the house: old plans, deeds showing boundaries, approvals for any earlier extension, and where you think the drains run. Photos of extensions you like help us price glazing and finishes accurately. If you're in a conservation area or on a newer estate, mention it, as it can affect permitted development.

Does Dudley Council need to approve my single-storey extension?

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