Renovate or convert?
Renovating keeps it a garage: a dry roof, a good door, a level floor, sound walls and light. Converting makes it a room you heat and use, with building regulations to meet: insulation to the standard, ventilation, and a fire escape window for a bedroom.

Side by side
| Renovating | Converting | |
|---|---|---|
| What it is | A sound, dry garage with a good door | A heated room: a bedroom, office or gym |
| Rules | No planning to renovate | Building regulations, sometimes planning |
| Insulation | Your choice | To the standard for a room |
| The door | A new garage door | Usually bricked up with a window |
If you're not sure
Do the renovation so it doesn't block a conversion later: insulate the roof while it's open, run the cables before the skim, and screed the floor to a level that suits a room. Converting: garageconversion.ie.
Plan your garage renovation
A few quick taps: what your garage needs, what the roof and door cost, and the order to do it in. Contact details come last, and only if you want a price.
A single garage, new roof and a roller door: €3,120 to €6,300, the old door taken away included.
How the estimate is worked out
Roof and door ranges are what Irish roofers and door companies publish for the same job: the lowest to the highest figure. A double garage roof is its area times the rate for the covering. Floors, walls, windows, insulation and electrics vary too much from garage to garage to price fairly without seeing them, so the builder prices those on a visit.
