Covering Crowthorne

Crowthorne sits 10 miles south-east of Reading, with Camberley 3 miles to the south-east and Wokingham 3 miles to the north-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 Crowthorne?

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.

  • Loft survey and head-height check
  • Design drawings and structural calculations
  • New floor joists, steels and staircase

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 can change the price or programme?

  • Head height under the ridge decides whether a conversion is practical.
  • Party wall notices are often needed for steels bearing on a shared wall.
