Who a bungalow extension suits
- Families wanting more space on one floor
- Homeowners planning for later life
- Bungalows on larger plots
Bungalow roofs are often hipped, which makes tying in an extension roof a careful job. We draw the roof junction early because it drives both the look and the cost.
Planning and approvals in Kelso
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.
Homes in conservation areas, national scenic areas and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
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.

We cover Kelso and the postcode districts TD5. The same team covers Galashiels (16 miles), Hawick (19 miles), Peebles (31 miles), all within easy reach.
Bonnyrigg, in Edinburgh and the Lothians, is roughly 33 miles from Kelso and also on our list. Scotland's housing includes sandstone villas, terraces and tenements in the cities and plenty of post-war and modern houses and bungalows elsewhere. A building warrant is needed before work starts.

Common questions in Kelso
Who do I contract with for a bungalow extension in Kelso?
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.
How long does a bungalow extension take to build in Kelso?
On site, typically 10 to 18 weeks once approvals are in place. Before that, allow 6–14 weeks design and approvals.
Do you cover all of Kelso?
Yes. We cover Kelso and the surrounding parts of Scottish Borders. Site visits are free and there is no obligation.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £1,720 to £3,330 per m² including VAT. Going upwards is priced after a structural survey.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
