Double-storey extensions in Bewdley

Double-storey extensions in Bewdley: approvals and local details

Most two-storey extensions in Bewdley need a planning application to Wyre Forest District Council. A two-storey rear extension can sometimes be permitted development, but only if it is no more than 3 m deep and at least 7 m from the rear boundary, among other conditions. Building Regulations approval is needed either way.

Councils often expect a side extension's first floor to be set back from the front wall, with its roof below the main ridge.
Scaffolding is usually up for most of the build, so think about access along the side of the house early.
Under permitted development, a rear extension of more than one storey can project no more than 3 metres and must be at least 7 metres from the rear boundary.

Options to consider in Bewdley

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.

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.
