Covering Renfrew
Renfrew sits 3 miles north-east of Paisley, with Clydebank 2 miles to the north and Paisley 3 miles to the south-west.
Homes in Renfrewshire and Inverclyde
Housing in Scotland includes tenements in the cities, sandstone villas, inter-war and post-war semis and a large number of bungalows, which often suit dormer and upward extensions.
What do you get with a loft conversion?
We start with the head height. You need roughly 2.2 m or more from the top of the ceiling joists to the underside of the ridge for a conversion to work without raising the roof. From there we design the staircase position, the type of conversion and the en-suite, and manage the whole build including fire safety and building control.
- Design drawings and structural calculations
- New floor joists, steels and staircase
- Dormer or rooflights, insulation and plasterboard

How is a loft conversion approved in Renfrew?
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.
In Scotland, dormers and other roof enlargements usually need planning permission, especially on the front of the house. A building warrant is needed before work starts in every case.
What should I think about before starting?
- Head height under the ridge decides whether a conversion is practical.
- The new staircase usually takes space from the landing or a bedroom below.
