Covering Beaconsfield
Beaconsfield sits 30 miles south of Milton Keynes, with Amersham 4 miles to the north and High Wycombe 5 miles to the west.
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 included in a loft conversion in Beaconsfield?
We start with the head height. You need roughly 2.2 m or more from the top of the ceiling joists to the underside of the ridge for a conversion to work without raising the roof. From there we design the staircase position, the type of conversion and the en-suite, and manage the whole build including fire safety and building control.
- Loft survey and head-height check
- New floor joists, steels and staircase
- Dormer or rooflights, insulation and plasterboard
How much should I budget for a loft conversion?

What approvals does a loft conversion need in England?
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?
- 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.
