Homes in Clwyd
Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.
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 regulations checks under Welsh rules
- Planning application to local design guidance
- En-suite, electrics and fire safety

How is a mansard loft conversion approved in Flint?
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 change the price or programme?
- A mansard nearly always involves party walls on both sides of a terrace.
- Council design guides often require natural slate and lead.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
