Single-storey extensions in Alcester

Single-storey extensions in Alcester: approvals and local details

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

Every extension needs Building Regulations approval, even when planning permission isn't required.
Wide glazed doors and roof lights make the biggest difference to how bright the new room feels, and to the final price.
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.

Choices to weigh up in Alcester

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.

Which postcodes in Alcester do you work in?

We cover B49 and the streets around them. If you're on the edge of Alcester, neighbouring Studley and Stratford-upon-Avon are covered too.

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.

Does Stratford-on-Avon District Council need to approve my single-storey extension?

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