Rothesay Garage Conversion Case Studies

Our portfolio of garage conversions across Rothesay and the Isle of Bute speaks for itself. Here are just a few real-world examples from the past year:
- Mount Stuart Road, Rothesay: We transformed a damp, underused garage into a bright home office with custom storage and triple-glazed windows. The client, a local business owner, now runs her company from home with stunning views of the Clyde.
- Craigmore Crescent: A family needed an extra bedroom for their teenager. We completed a full structural garage conversion, including new insulation, heating, and a skylight, all within three weeks. The family stayed in the house throughout with minimal disruption.
- Ardbeg Road: A retired couple wanted a hobby room and guest suite. We converted their garage into a flexible space with a wet room and underfloor heating, perfect for visiting grandkids or creative projects.
- Port Bannatyne: For a client with a classic car, we split the garage, half remained for storage, half became a home gym. Clever design, robust flooring, and moisture control made it a year-round retreat.
Every project is different, but our approach is always the same: listen, design, deliver. We know Rothesay’s homes, from the grandest villas to the cosiest semis, and we’re proud to help local families make the most of their space.

Permitted Development Rules for Rothesay Garages

Most garage conversions in Rothesay fall under permitted development, meaning you won’t need full planning permission if you’re not changing the building’s footprint or height. However, there are exceptions, especially for listed buildings, conservation areas, or properties near Rothesay Castle and the Esplanade. Our team has decades of experience navigating Argyll & Bute Council’s planning rules, so you won’t get caught out by red tape.
We handle all the paperwork, from building warrants to structural calculations. If your home is in a conservation area like Mount Stuart or near the historic centre, we’ll advise on any extra steps needed. We’ve secured approvals for everything from simple garage-to-office conversions to complex structural garage conversions in older sandstone homes.
- Most garage conversions: permitted development, no planning permission needed
- Listed buildings/conservation areas: expert guidance and full support
- All work meets Scottish building standards for insulation, fire safety, and ventilation
- Free planning checks included with every quote
Don’t risk delays or costly mistakes. Let us check your property and handle the process from start to finish, so you can focus on enjoying your new space.
