Loft conversions in Hall Green

Loft conversions in Hall Green: approvals and local details

Before work starts on your loft conversion in Hall Green, two things get checked: whether planning permission from Birmingham City Council is needed, and how Building Regulations approval will be obtained. If you share a wall with a neighbour, the Party Wall etc. Act 1996 may apply as well.

A dormer on the roof slope facing the street, or one that rises above the ridge, needs a planning application.
Permitted development allows up to 40 m³ of extra roof volume on a terraced house and 50 m³ on other houses.
Roof lights can usually go in without planning permission as long as they don't project more than 150 mm from the roof slope.

Which options suit homes in Hall Green?

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.

Roof-light conversion

The simplest option: the roof shape stays the same and roof windows are fitted into the slope. It works when there's already enough head height, keeps costs down, and is often permitted development because roof lights can project up to 150 mm from the roof plane. You do lose some usable floor area under the sloping ceilings.

How much should you budget in Hall Green?

Guide prices start at £22,000 and run to £72,000 depending on size and specification. A rear dormer with a double bedroom and shower room on a three-bed semi: around £42,000–£52,000.

We cover B28 and the streets around them. If you're on the edge of Hall Green, neighbouring Acocks Green and Shirley are covered too.

How long does a loft conversion take?

Most take 6–10 weeks on site, with roof-light conversions at the shorter end and hip-to-gable or mansard work at the longer end. Allow time beforehand for drawings, a lawful development certificate or planning decision, and party wall notices, which need two months on a semi or terrace. We plan the start date around those periods so nothing is left waiting.

Will I need permission from the council in Hall Green?

Usually building control, and sometimes planning. Birmingham City Council is the planning authority for Hall Green; Building Regulations approval comes from its building control team or a registered building control approver. We'll tell you which applies after the survey.
