Dormer loft conversions in Nottinghamshire

Covering Nottinghamshire

Our dormer loft conversions service in Nottinghamshire covers Nottingham, Mansfield, Worksop and Newark-on-Trent and more.

Homes in the East Midlands

Across the East Midlands you find everything from city terraces to modern estates and stone villages, so the right extension depends a lot on the street and the materials around it.

What goes into 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.

Do you need permission for a dormer loft conversion in Nottinghamshire?

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 change the price or programme?

Dormers on the front of the house facing a road are not permitted development in England.
Dormer cheeks close to a shared wall can trigger the Party Wall Act.
