Extensions in and around Vale of Leven
Our survey diary covers Vale of Leven, including G82. We also work in nearby Dumbarton (2 miles), Clydebank (8 miles), Bearsden (10 miles), Bishopbriggs (15 miles).
Erskine, in Renfrewshire and Inverclyde, is roughly 7 miles from Vale of Leven and also on our list. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Do I need planning permission in Vale of Leven?
In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted. Separately, almost every extension needs a building warrant from the council before work starts.
The planning position for a specific Vale of Leven address depends on its history and any designations, which is why we check it at the first visit.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
Applications are decided by your council as planning authority.

Is a side return extension right for your house?
- Homes where the garden is too small to lose much depth
- Narrow galley kitchens
- Victorian and Edwardian terraces with a rear outrigger
Light is the design problem. A side return can make the middle of the house darker if the roof is solid, so we model the daylight and usually recommend a glazed slope or a run of rooflights along the boundary edge.

Side return extension questions answered
Do you cover all of Vale of Leven?
Yes. We cover Vale of Leven and the surrounding parts of Dunbartonshire. Site visits are free and there is no obligation.
Who do I contract with for a side return extension in Vale of Leven?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Vale of Leven, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will the kitchen be darker?
Not if the roof is designed well. A glazed roof or a line of rooflights along the boundary usually makes the room brighter than before.
Can I combine a side return with a rear extension?
Yes. That combination is a wraparound extension, which adds the most space to a terraced house.
