What goes into 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.
- Planning and building regulations checks under Welsh rules
- Structural design and party wall process
- Staircase, insulation and fit-out
What will a mansard loft conversion cost?
What mansard loft conversions typically cost. These are guide ranges; the written quote for your house replaces them.
| Mansard loft conversions | Guide price incl. VAT |
|---|---|
| Rear mansard | £65,000 to £85,000 |
| Front and rear (double) mansard | £80,000 to £110,000 |
What approvals does a mansard loft conversion need in Wales?
Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.
This needs full planning permission from your council in Wales. We prepare and submit the application and deal with the planning officer on your behalf.
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.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
Mansard loft conversions: common questions
Why choose a mansard over a dormer?
A mansard gives more usable space and often fits a street better where neighbours already have one.
Will I need party wall agreements?
Very likely, as the work affects the walls shared with both neighbours on a terrace.
Who deals with the council for a project in Pontarddulais?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
