Single-storey extensions in Malvern

Before your single-storey extension in Malvern

In Malvern, Malvern Hills District 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.

A lawful development certificate from Malvern Hills District Council confirms in writing that a permitted development extension is lawful, which helps when you sell.
Wide glazed doors and roof lights make the biggest difference to how bright the new room feels, and to the final price.
Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.

Which option fits your home?

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.

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 in Malvern: common questions

Do I need to tell my neighbours about an extension?

You don't need their permission for permitted development, but you will usually need to involve them. Under the prior approval route the council writes to adjoining neighbours and gives them 21 days to comment. If the build is on the boundary or the foundations are deep and close to their house, the Party Wall Act requires formal written notice. A friendly conversation before any notice arrives usually makes everything smoother.

Do you cover Malvern?

Yes. Malvern (WR14) is about 31 miles from our West Bromwich base and inside the area we cover. Call 0800 088 6248 or send the form on this page to book a free survey.

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.

Does Malvern Hills District Council need to approve my single-storey extension?

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