Extensions in and around Dunbartonshire
Towns we cover in Dunbartonshire include Bearsden, Clydebank, Vale of Leven, Bishopbriggs, Dumbarton, Kirkintilloch. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Who a wraparound extension suits
- Terraced houses that want the largest ground floor possible
- Families who want kitchen, dining and living in one space
- Semi-detached houses with a side passage
The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.
Planning and approvals in Dunbartonshire
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 Dunbartonshire 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.

Wraparound extension questions answered
How long does a wraparound extension take to build in Dunbartonshire?
On site, typically 14 to 20 weeks once approvals are in place. Before that, allow 8–16 weeks design and approvals.
Who do I contract with for a wraparound extension in Dunbartonshire?
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.
Do I need building regulations approval in Dunbartonshire?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
How much does a wraparound extension cost?
Our guide range is about £1,960 to £3,630 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £56,000 to £71,500 in Dunbartonshire before design and council fees.
