Covering Bellshill
Across ML4, we can visit, measure and advise. The same team covers Motherwell (2 miles), Coatbridge (3 miles), Blantyre (3 miles), Hamilton (4 miles), all within easy reach.
For homes towards Dunbartonshire, Kirkintilloch is around 10 miles away. 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.
Will the council need to approve it?
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.
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.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Applications are decided by your council as planning authority.

Questions people ask about side return extensions
Will my neighbours in Bellshill be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
Do you cover all of Bellshill?
Yes. We cover Bellshill and the surrounding parts of Lanarkshire. Site visits are free and there is no obligation.
How long does a side return extension take to build in Bellshill?
On site, typically 10 to 14 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
How much does a side return extension cost?
Our guide range is about £2,060 to £3,720 per m² including VAT, so a typical 2 m × 5.5 m infill lands around £25,500 to £32,500 at standard spec in Bellshill, more in London.
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.
