Loft conversions in Bartley Green

Loft conversions in Bartley Green: approvals and local details

Birmingham City Council is the planning authority for Bartley Green. If your plans need permission, apply early: householder applications have an eight-week target for a decision. Building Regulations approval and inspections run alongside the build.

Roof lights can usually go in without planning permission as long as they don't project more than 150 mm from the roof slope.
Mains-powered, interlinked smoke alarms on every floor are part of a compliant loft conversion.
A dormer on the roof slope facing the street, or one that rises above the ridge, needs a planning application.

Which option fits your home?

Mansard conversion

The rear roof slope is rebuilt almost vertically, at around 70 degrees, with a flat top and windows set into it. It gives the most space but changes the roof shape significantly, so it normally needs a planning application. It can suit terraces where a dormer would be too limited, and it's the most expensive of the common types.

Rear dormer conversion

A box-shaped extension built out from the rear roof slope, with vertical walls and a flat roof, giving full standing height across most of the room. It suits semis and terraces because it adds the most usable space for the money. Under permitted development it must be set back from the eaves and stay within the volume allowance.

Your questions answered

Will I lose space on the landing?

Usually very little, because the new staircase normally sits above the existing one. Sometimes part of a box room or a cupboard is used to fit the stair in, especially where head height is tight. We show you exactly where the stair lands on the drawings before you agree to anything, because its position decides how both floors work.
