Covering Alloa
Alloa sits 6 miles east of Stirling, with Stirling 6 miles to the west and Grangemouth 8 miles to the south.
Homes in the Forth Valley
Scottish homes range from city tenements and sandstone terraces to bungalows and modern estates, and the building warrant process shapes the programme for every project.
What is 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

Planning and building rules in Alloa
Projects in Scotland need a building warrant from the council before any building work starts, and a completion certificate once it is finished. Planning permission is a separate decision. The Party Wall etc. Act does not apply in Scotland; shared walls are governed by title deeds and the law of the tenement where relevant.
This needs planning permission and a building warrant from your council in Scotland before work starts.
What should Alloa homeowners check first?
- The roof is open for longer than with a dormer, so weather protection matters.
- Council design guides often require natural slate and lead.
What happens after I enquire?
- 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.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
