A garage conversion turns an integral or attached garage into a warm, habitable room by insulating the floor, walls and ceiling, replacing the garage door with a wall and window, and adding heating, lighting and finishes.
Whether you live in one of the larger towns, such as Bearsden, Clydebank, Vale of Leven and Bishopbriggs, or somewhere quieter in Dunbartonshire, the way we handle a garage conversion is identical. We survey, agree the specification with you, and confirm a fixed price on paper. Everything is planned under the regulations in force in Scotland, and guide costs in Scotland sit at £11,500–£27,000 with VAT.

Homes in Dunbartonshire
Clydebank was heavily rebuilt after wartime bombing and has tenements and post-war estates, while Dumbarton has sandstone tenements and Victorian housing. Bearsden and Milngavie are known for Victorian villas and interwar bungalows, and Kirkintilloch mixes older terraces with post-war semis and newer developments.
Bungalows commonly suit loft conversions with dormers, and villas often take kitchen extensions and landscaping. Tenement flats may need window replacement, and harled homes often need re-rendering.
The west of Scotland gets frequent heavy rain and wind, so driving-rain exposure is a key consideration for render and pointing.
Do you need permission in Dunbartonshire?
Each UK nation sets its own consent rules, and Dunbartonshire is in Scotland. What follows is a plain summary; we check the specifics for your property with the council before pricing anything.
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.
From survey to handover
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a garage conversion so the price reflects your home.
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.
Plan and prepare
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.
The work itself
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.
How we work
Frequently asked questions
Which postcodes in Dunbartonshire do you cover?
We cover G13, G60, G82 and G64, along with the rest of Dunbartonshire. 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 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.
Can you combine a garage conversion with other work?
Yes. Because we manage several trades under one contract, we can plan a garage conversion alongside other work on your Dunbartonshire home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
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.
How much does a garage conversion cost?
A typical single garage conversion costs £11,500–£27,000, depending on whether the garage is integral, attached or detached and what the room is for. Integral garages usually cost least because the walls and roof are already sound. Adding a shower room, upgrading a flat roof or levelling a sloping floor adds cost. As a guide, allow roughly £550–£1,100 per square metre plus fixed costs. We confirm a fixed price after the survey.
