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

England, Wales, Scotland and Northern Ireland each handle planning a little differently. Dumfries and Galloway comes under Scotland, covered below, and we raise any questions with the council before your quote is finalised.

In Scotland, converting an attached or integral garage usually needs no planning permission unless a condition restricts it.

A building warrant is normally needed, because the work changes the use of the space and alters the walls and insulation.

Rules change and every property is different, so we check the planning history and constraints for your address before we quote.

How does the job run?

  1. A visit to your home

    We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a garage conversion, and photograph or measure anything the quote needs to reflect.

  2. Your fixed price

    Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.

  3. Dates and permissions

    Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.

  4. Build and hand over

    The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.

Frequently asked questions

Who do I deal with during the job?

One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.

Will losing the garage affect parking?

Losing a garage can matter if your street has parking pressure or your property deeds or planning conditions require off-street parking. Many garages are too narrow for modern cars, so in practice the driveway often provides the parking anyway. We check for planning conditions affecting the garage before quoting. If you need extra parking, we can also price a driveway extension.

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.

Will I need building regulations approval?

A garage conversion needs building regulations approval because the space becomes a habitable room. Building control checks that the new wall in the door opening has proper foundations, that the floor has a damp-proof membrane and insulation, and that walls and ceiling meet insulation standards. Ventilation, fire safety and escape routes are also checked. In Scotland a building warrant is normally needed before work starts.

Does the floor need raising?

Garage floors are usually lower than the house floor and slope towards the door for drainage. Most conversions raise the floor with a damp-proof membrane, insulation and either a screed or a timber floor, so it lines up with the house and removes the step. The final level depends on ceiling height and the door into the house. We measure both during the survey.
