Loft conversions in Aston

Before your loft conversion in Aston

In Aston, Birmingham City Council decides planning questions. We check permitted development limits and any local restrictions at the survey, then deal with the Building Regulations side so you receive a completion certificate when the work is signed off.

Mains-powered, interlinked smoke alarms on every floor are part of a compliant loft conversion.
The new staircase usually needs 2 metres of headroom, with a little leeway allowed for loft conversions.
Permitted development allows up to 40 m³ of extra roof volume on a terraced house and 50 m³ on other houses.

Choices to weigh up in Aston

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.

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.
