Single-storey extensions in Codsall

Planning your single-storey extension in Codsall

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

Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.
A lawful development certificate from South Staffordshire Council confirms in writing that a permitted development extension is lawful, which helps when you sell.
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?

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.

Your questions answered

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.
