Mansard loft conversions in Burnley

We take on mansard loft conversions in Burnley as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Burnley

Burnley is about 19 miles east of Preston. We also cover Nelson (3 miles to the north-east), Accrington and Rawtenstall.

Homes in the North West

Across the North West, Victorian terraces, inter-war semis and modern estates all feature, and brick or stone matching is chosen to suit each street.

What do you get with a mansard loft conversion?

A mansard loft conversion replaces one or both slopes of a roof with a near-vertical wall, typically at 70 degrees, with small dormer windows set into it. It creates almost a full extra storey and is common on terraced houses in towns and cities, particularly in London.

  • Roof removal and new mansard frame
  • Staircase, insulation and fit-out
  • En-suite, electrics and fire safety

How much should I budget for a mansard loft conversion?

Mansard loft conversionsGuide price incl. VAT
Rear mansard£65,000 to £85,000
Front and rear (double) mansard£80,000 to £110,000

Do you need permission for a mansard loft conversion in Burnley?

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.

Mansard conversions change the shape of the roof significantly, so they usually need planning permission in England.

What can affect a mansard loft conversion?

  • The roof is open for longer than with a dormer, so weather protection matters.
  • Council design guides often require natural slate and lead.

How does the project run?

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
