Housing across Dumfries and Galloway
Dumfries is known for red sandstone buildings, and older towns across the region, such as Kirkcudbright and Castle Douglas, have Georgian and Victorian streets. Rural homes are often harled whinstone or sandstone farmhouses and cottages under slate roofs, with post-war and modern housing on the edges of towns such as Stranraer and Annan.
Stone and harled homes commonly need lime-based repairs, re-harling and roof slating work. Town houses suit extensions and loft conversions, and rural properties often take porches, driveways and fencing.
Mild but wet, with exposed Solway and west coasts and remote rural sites that can need extra planning for access.
Planning and building rules in Dumfries and Galloway
Each UK nation sets its own consent rules, and Dumfries and Galloway is in Scotland. What follows is a plain summary; we check the specifics for your property with the council before pricing anything.
In Scotland, dormers are only permitted development in limited cases (for example, at least 10 m from the boundary the dormer faces, and not in conservation areas), so many loft conversions with dormers need planning permission. Rooflight-only conversions are often simpler.
A building warrant is required for a loft conversion in Scotland, covering structure, stairs, insulation and fire safety. There is no Party Wall Act.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
Free site survey
A free survey comes first. It gives us what we need to price a loft conversion properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Quote in writing
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Booking the work
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
Build and hand over
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
How we work
Questions about a loft conversion in Dumfries and Galloway
Can I put a bathroom in my loft?
A bathroom or shower room can usually be added in a loft conversion if waste pipes can reach the soil stack with enough fall, or a pumped system can be used. Dormers make this easier because they give standing height for a shower. Water pressure, extraction and the position of the boiler also matter. We plan the bathroom layout at the design stage so pipes are hidden in the structure.
What fire safety measures does a loft conversion need?
A loft conversion needs a safe way out in a fire, because the new room is high above the ground. This usually means a protected stair route down to an exit, with fire doors onto the stairway, mains-linked smoke alarms on each floor and sometimes an escape window. The exact approach depends on your house layout. Building control checks these measures before signing off the work.
Which postcodes in Dumfries and Galloway do you cover?
We cover DG1, DG9, DG12 and DG1, along with the rest of Dumfries and Galloway. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
Can we stay at home during a loft conversion?
Most people stay at home during a loft conversion, because much of the work happens from scaffolding outside and the roof is opened up from above. The most disruptive point is near the end, when we break through the ceiling to fit the new staircase, which usually takes a few days. We put up dust screens on the landing and plan noisy work for reasonable hours.
Do you cover Dumfries, Stranraer and Annan?
Yes. As well as Dumfries and Galloway, we cover Dumfries, Stranraer and Annan and the rest of Dumfries and Galloway. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
