Which options suit homes in Heath Hayes?

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.

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.

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

Who approves double-storey extensions in Heath Hayes?

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.
