Dormer loft conversions in Stourbridge

Covering Stourbridge

Alongside Stourbridge, we also cover Brierley Hill, Dudley (4 miles to the north-east) and Halesowen.

Homes in the West Midlands

Red-brick terraces and inter-war semis make up much of the housing in the West Midlands, which suits rear extensions, dormer lofts and hip-to-gable conversions, with more modern estates on the edges of the towns.

What is a dormer loft conversion?

Rear dormers on terraced and semi-detached houses are often permitted development in England. We size the dormer to fit the volume allowance, clad it to suit the house (tile-hanging, render, slate or zinc) and fit out the room and en-suite below.

Planning and building rules in Stourbridge

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

In England many loft conversions are permitted development: the extra roof volume must stay within 40 m³ on a terraced house or 50 m³ on a semi or detached house, nothing can sit higher than the existing ridge, no dormer can face a road on the main elevation, and side windows must be obscure-glazed and non-opening below 1.7 m.

What can affect a dormer loft conversion?

Dormers on the front of the house facing a road are not permitted development in England.
A flat dormer roof needs proper falls and a quality membrane.

What people ask before starting

Is a dormer permitted development?

Rear dormers in England often are, within the 40 m³ (terrace) or 50 m³ (semi or detached) volume allowance. Front dormers facing a road are not.

Can a dormer include a bathroom?

Yes. The full head height in a dormer makes it the best place for a shower room or en-suite.

Can you visit a house in Stourbridge to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
