Double-storey extensions in Hednesford

Planning your two-storey extension in Hednesford

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

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

Which option fits your home?

Mixed-height extension

A two-storey section at the side with a single-storey section running across the back. This keeps the first floor away from neighbours' windows while still giving a wide kitchen-diner below. It's a practical compromise where planners have concerns about a full-depth two-storey rear extension, and it often simplifies the roof.

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.

What does your two-storey extension cost in Hednesford?

Expect to budget between £52,000 and £135,000 depending on size and specification in Hednesford. A two-storey side extension on a three-bed semi, about 32 m² over two floors: typically £68,000–£88,000.

Questions about double-storey extensions in Hednesford

Can we stay in the house while you build?

Most families do. The early stages are outside, and the existing house stays closed off until the shell is weathertight. The harder weeks are when openings are cut through on both floors, which brings dust and noise into bedrooms and the kitchen. We sheet off openings, lock up securely every night and agree in advance which rooms you'll lose and when.

Which postcodes in Hednesford do you work in?

We cover WS12 and the streets around them. If you're on the edge of Hednesford, neighbouring Heath Hayes and Cannock 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 Hednesford?

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