Covering Godalming
We work in Godalming (GU7) and the places around it, including Guildford, Aldershot and Farnham.
Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
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.
- Volume calculation and permitted development check
- Lawful development certificate or planning drawings
- Steelwork and new floor structure

How is a dormer loft conversion approved in Godalming?
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 should I think about before starting?
- 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.
What are the steps?
