Single-storey extensions in Bromsgrove

Single-storey extensions in Bromsgrove: approvals and local details

Before work starts on your single-storey extension in Bromsgrove, two things get checked: whether planning permission from Bromsgrove District 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.

A lawful development certificate from Bromsgrove District Council confirms in writing that a permitted development extension is lawful, which helps when you sell.
Every extension needs Building Regulations approval, even when planning permission isn't required.
If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.

Which option fits your home?

Rear kitchen-diner extension

The usual layout: a 3–6 metre extension across all or part of the back wall, with the old rear wall replaced by a steel beam so the new and existing rooms become one space. Roof lights or a lantern bring daylight into the middle of the house, and bifold or sliding doors open onto the garden.

Side or side-return extension

Uses the strip of land beside the house, often a passage or driveway. Under permitted development a side extension can be up to half the width of the original house and no more than 4 metres high. On a terrace with a narrow side return, it can widen a galley kitchen considerably without eating into the garden.

How much should you budget in Bromsgrove?

Single-storey extensions in Bromsgrove: common questions

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.
