Double-storey extensions in Kinver

Planning your two-storey extension in Kinver

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

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.
The householder planning fee in England is £548 from April 2026, paid to South Staffordshire Council when you apply.

Which options suit homes in Kinver?

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.

Your questions answered

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.

What will the council look at when deciding planning?

Councils judge two-storey extensions mainly on their effect on neighbours and the street. They look at loss of light and outlook next door, overlooking from upstairs windows, and whether the extension sits comfortably with the house, often expecting side extensions to be set back and lower than the main roof. Many councils publish householder design guides, and following yours closely improves the chance of approval.

Will I need permission from the council in Kinver?

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.
