Double-storey extensions in Stourport-on-Severn: approvals and local details

Expect to apply to Wyre Forest District Council for planning permission for a two-storey extension in Stourport-on-Severn; side extensions over one storey always need it. We prepare the drawings, and the structural work also needs Building Regulations approval.

Scaffolding is usually up for most of the build, so think about access along the side of the house early.
New first-floor bedrooms normally need an escape window with at least 0.33 m² of clear openable area.
An upstairs en-suite is simplest when the new bathroom sits close to the existing soil stack.

Options to consider in Stourport-on-Severn

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.

Before you book in Stourport-on-Severn

Is a double-storey extension better value than a single-storey one?

Per square metre, usually yes. Foundations and roofs are the expensive parts of any extension, and on a two-storey build they serve twice the floor area. You'll pay more in total and planning is less certain, but if you need a bedroom as well as downstairs space, building both together normally costs less than two separate projects years apart.

Which postcodes in Stourport-on-Severn do you work in?

We cover DY13 and the streets around them. If you're on the edge of Stourport-on-Severn, neighbouring Kidderminster and Bewdley are covered too.
