Covering Gloucestershire
We cover Gloucestershire, including Gloucester, Cheltenham, Stroud and Kingswood, and the towns around them.
Homes in the South West
In the South West, matching local stone, render or slate is often the main design question, and conservation areas and listed buildings are common in historic towns.
What does a loft conversion involve?
A loft conversion turns an unused roof space into habitable rooms, usually a bedroom with an en-suite, by strengthening the floor, adding a staircase, insulating the roof and putting in windows. The type you need depends on the roof: rooflight, dormer, hip-to-gable or mansard.
- Planning or lawful development certificate
- New floor joists, steels and staircase
- En-suite, electrics, heating and fire safety upgrades

How is a loft conversion approved in Gloucestershire?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 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 Gloucestershire homeowners check first?
- Fire safety rules can mean new fire doors on the floors below.
- Party wall notices are often needed for steels bearing on a shared wall.
