Double-storey extensions in Stoke-on-Trent

Before your two-storey extension in Stoke-on-Trent

Planning permission from Stoke-on-Trent City Council is the first hurdle for most double-storey extensions in Stoke-on-Trent. Householder applications have an eight-week target for a decision, and Building Regulations approval and the Party Wall Act may also apply.

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.
Scaffolding is usually up for most of the build, so think about access along the side of the house early.
An upstairs en-suite is simplest when the new bathroom sits close to the existing soil stack.

Choices to weigh up in Stoke-on-Trent

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.

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.

Double-storey extensions in Stoke-on-Trent: common questions

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.

Which postcodes in Stoke-on-Trent do you work in?

We cover ST1, ST4 and the streets around them. If you're on the edge of Stoke-on-Trent, neighbouring Stafford and Penkridge are covered too.

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 Stoke-on-Trent?

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