What does a mansard loft conversion involve?

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.

Planning and building rules in Greater Manchester

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

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

What can change the price or programme?

  • Council design guides often require natural slate and lead.
  • 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. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  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.

Why choose a mansard over a dormer?

A mansard gives more usable space and often fits a street better where neighbours already have one.

Who deals with the council for a project in Greater Manchester?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
