Single-storey extensions in Hagley

Planning your single-storey extension in Hagley

Planning applications and lawful development certificates for Hagley go to Bromsgrove District 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.

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.
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.

Which options suit homes in Hagley?

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.

What does your single-storey extension cost in Hagley?

Single-storey extensions in Hagley: 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.

How do I book a survey in Hagley?

Send the form on this page, use the guide-price tool or call 0800 088 6248 free. We'll ask a few questions about your single-storey extension and arrange a time to visit.

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.

Who approves single-storey extensions in Hagley?

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