Plenty of garages around Dundee are too narrow for a modern car and end up storing bikes, paint tins and a freezer. Converting one into a proper room is usually the cheapest way to gain living space without moving, but the paperwork and the build are more involved than many people expect. Here is what it costs, what the council needs from you and how the job runs.
For a standard attached single garage of roughly 15 to 18 square metres, most conversions in Dundee, Broughty Ferry and Monifieth currently fall somewhere between £15,000 and £30,000, including design, warrant drawings and finishes. A simple home office or playroom sits at the lower end. Adding a shower room, a utility area or knocking through into the kitchen pushes the figure up, and a double garage or a detached one that needs new services can go well beyond that range.
The price depends far more on the condition of the existing structure than on its size. The main things that move the cost are:
Turning a garage into a habitable room needs a building warrant, and it must be granted before work starts. For homes in the city you apply to Dundee City Council building standards. For Monifieth, Carnoustie and the rest of Angus it is Angus Council. The fee is set on a sliding scale based on the value of the work and is typically a few hundred pounds for a job of this size. Allow around four to eight weeks for approval, longer if the council asks for extra information.
Planning permission is often not needed where the outside changes are limited to replacing the garage door with a wall and window in matching materials. There are exceptions. Homes in conservation areas such as parts of Broughty Ferry and the West End, listed buildings and flats are treated differently, and some newer estates have conditions or title deed burdens requiring the garage to be kept for parking. It is worth checking both before you spend money on drawings.
At the end, the council must accept a completion certificate. Without it you can have real trouble when you come to sell or remortgage, which is why unwarranted conversions carried out years ago so often surface during a home report.
The warrant drawings have to show that the new room meets the same standards as any other room in the house. In practice that means the following:
From first visit to finished room, plan on three to four months. Survey and drawings take two to four weeks, the warrant another four to eight, and the build itself usually three to six weeks on site. Most of the mess stays in the garage until the opening into the house is formed, so you can live at home throughout.
Before asking for quotes, decide what the room is for, since a bedroom, an office and a utility room have different needs for sockets, heating and plumbing. Think about where the contents of the garage will go, and ask each contractor whether their price includes the drawings, the warrant fee, the engineer and the completion certificate. A low quote that leaves these out is rarely the cheapest by the end.
