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

Planning and building rules in Heanor

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.

Mansard conversions change the shape of the roof significantly, so they usually need planning permission in England. Many councils publish guidance on mansard design.

What can affect a mansard loft conversion?

  • The roof is open for longer than with a dormer, so weather protection matters.
  • Scaffolding and a temporary roof are usually needed.

From first call to completion

  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. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

What people ask before starting

Does a mansard need planning permission?

Almost always, because it changes the roof profile.

Will I need party wall agreements?

Very likely, as the work affects the walls shared with both neighbours on a terrace.

Can you visit a house in Heanor to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
