Double-storey extensions in Cheslyn Hay

What should you know before starting in Cheslyn Hay?

Most two-storey extensions in Cheslyn Hay need a planning application to South Staffordshire Council. A two-storey rear extension can sometimes be permitted development, but only if it is no more than 3 m deep and at least 7 m from the rear boundary, among other conditions. Building Regulations approval is needed either way.

An upstairs en-suite is simplest when the new bathroom sits close to the existing soil stack.
Party wall notices take one or two months to run, so they're best served as soon as planning is granted.
Scaffolding is usually up for most of the build, so think about access along the side of the house early.

Choices to weigh up in Cheslyn Hay

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.

Combined side and rear

An L-shaped two-storey build wrapping the side and back of the house gives the biggest gain, sometimes two extra bedrooms. It's a substantial project with more steel and a complex roof junction, and it will need a householder planning application. Expect a longer programme and a careful plan for keeping the house secure while the roofs are joined.

Double-storey extensions in Cheslyn Hay: common questions

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.

Which postcodes in Cheslyn Hay do you work in?

We cover WS6 and the streets around them. If you're on the edge of Cheslyn Hay, neighbouring Great Wyrley and Cannock are covered too.

What paperwork will I have at the end?

You'll get the building control completion certificate, the electrical installation certificate, your planning decision notice and the manufacturers' guarantee documents for windows, doors and roof products, with their terms set out in your quote. Keep these together, as a buyer's solicitor will ask for them when you sell. Ask us for current insurance details with your quote.

Does South Staffordshire Council need to approve my two-storey extension?

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