Covering Hawick
Across TD9, we can visit, measure and advise. The same team covers Galashiels (16 miles), Kelso (19 miles), Peebles (24 miles), all within easy reach.
Just over the Dumfries and Galloway border, Annan is about 34 miles away. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
What we take care of
- Flat or pitched roof, rooflights or lantern
- Foundations, drainage and groundworks
- Walls, steel beams and the new opening into the house
- Doors, windows, insulation, plastering and first fix to finish
- Measured survey and design
Depth is the big decision. Every extra metre adds floor area but also takes garden and can push you out of permitted development. We draw the room at two or three depths so you can see the trade-off in space, light and cost before anything is fixed.
Planning rules that apply in Hawick
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
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.

Single-storey extension questions answered
How long does a single-storey extension take to build in Hawick?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.
Do you cover all of Hawick?
Yes. We cover Hawick and the surrounding parts of Scottish Borders. Site visits are free and there is no obligation.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Hawick, 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 I need a steel beam?
Almost always. Opening up the rear wall to join the new room to the house needs a beam, usually steel, sized by a structural engineer. It is included in our quotes.
How much does a single-storey extension cost per square metre?
Our guide range is about £1,720 to £3,330 per m² including VAT, depending on specification. A standard-spec 4 m × 5 m room usually lands at £40,000 to £51,000 in Hawick, plus design and council fees.
