Double-storey extensions in Droitwich Spa

Double-storey extensions in Droitwich Spa: approvals and local details

Expect to apply to Wychavon District Council for planning permission for a two-storey extension in Droitwich Spa; side extensions over one storey always need it. We prepare the drawings, and the structural work also needs Building Regulations approval.

An upstairs en-suite is simplest when the new bathroom sits close to the existing soil stack.
Scaffolding is usually up for most of the build, so think about access along the side of the house early.
Under permitted development, a rear extension of more than one storey can project no more than 3 metres and must be at least 7 metres from the rear boundary.

Which options suit homes in Droitwich Spa?

Two-storey rear extension

Adds depth to both floors across the back of the house: a kitchen-diner below and a larger bedroom or new bathroom above. Permitted development only covers projections up to 3 metres and at least 7 metres from the rear boundary, so many rear builds still need planning. Overlooking and loss of light to neighbours are the usual tests.

Building over an existing extension

Adds a first floor on top of an existing single-storey extension or attached garage. It can cost less because the footprint already exists, but a structural engineer must check the existing foundations and walls first, and they sometimes need strengthening. The old flat roof comes off and the new floor is tied into the main house.

Do you cover Droitwich Spa?

Yes. Droitwich Spa (WR9) is about 19 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 double-storey extension take?

Plan on 14–22 weeks on site, depending on size and roof complexity. Before that, allow time for drawings, a planning decision (councils aim to decide householder applications within 8 weeks), Building Regulations drawings and party wall notices. It's worth starting the design well ahead of when you need the space, because the approvals stage can take as long as the build.

Will I need permission from the council in Droitwich Spa?

Usually both. Most two-storey extensions need a planning application to Wychavon District Council, and the structural work needs Building Regulations approval from its building control team or a registered building control approver.
