Double-storey extensions in Great Wyrley

What should you know before starting in Great Wyrley?

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

Scaffolding is usually up for most of the build, so think about access along the side of the house early.
A side extension of more than one storey always needs a householder planning application.
The householder planning fee in England is £548 from April 2026, paid to South Staffordshire Council when you apply.

Which option fits your home?

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.

Two-storey side extension

Built over the side of the house, often where a driveway or old garage sits. It can create a garage, utility or study downstairs with a double bedroom above. Councils often expect the upper floor to be set back from the front and the roof to sit lower than the main ridge, so the design needs care to win approval.

Double-storey extensions in Great Wyrley: 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.

Keep these together, as a buyer's solicitor will ask for them when you sell. Ask us for current insurance details with your quote.

Will I need permission from the council in Great Wyrley?

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.
