Covering Harlow
We work in Harlow (CM17, CM18, CM92) and the places around it, including Hoddesdon, Bishop's Stortford and Waltham Abbey.
Homes in the East of England
Housing in the East of England ranges from post-war estates and modern developments to timber-framed and period homes in historic towns, so permitted development checks and conservation controls both feature regularly.
What does a dormer loft conversion involve?
A dormer loft conversion builds a box-shaped extension out from the rear slope of the roof, creating vertical walls and full head height across most of the new floor. It is the most popular type of loft conversion because it gives the most usable space for the cost.
- Lawful development certificate or planning drawings
- Steelwork and new floor structure
- Staircase, insulation and plasterboard

How is a dormer loft conversion approved in Harlow?
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.
