Garage conversions by county
A garage conversion in Ireland costs €15,000 to €25,000 at a standard finish, €20,000 to €30,000 mid-range and €30,000 to €45,000 at a high spec, VAT included. Dublin and the commuter counties run up to a fifth higher. A shower room adds €4,000 to €8,000 at a basic finish or €10,000 to €18,000 mid-range, and opening it into the house with a steel beam €2,000 to €4,000.

Plan your garage conversion
Four quick taps, and your plan fills in as you answer: the cost in your county, the planning position for your kind of garage and how many weeks it takes. Contact details come last, and only if you want a builder to price it.
An attached garage made into a bedroom, mid-range finish: €20,000 to €30,000, including VAT.
How the estimate is worked out
A garage conversion is priced as one job, because the walls, roof and floor slab are already standing: insulating the floor, walls and roof, building up the door opening with a window, wiring, heating, plastering and the finish. The range for your finish is adjusted to your county the same way building rates move between regions of Ireland, VAT at 13.5% included. A shower room, a small kitchen or a steel beam into the house go on top. Totals are rounded to the nearest €1,000. Use it to plan with. It isn't a quote: a builder prices your garage after seeing it.

County questions
Which counties do you cover?
All 26 counties. Your plan goes to one vetted builder who covers your county.
Why do garage conversion prices vary by county?
Building costs follow house prices: Dublin and the commuter counties cost most, then the rest of Leinster, Munster, and Connacht and Ulster.
Are the planning rules the same in every county?
An attached garage at the side or back of the house can be converted without planning permission under Class 1, as long as the garage isn't made bigger and the conversion, added to every extension built since 1 October 1964, stays within 45 m². A garage at the front, one built into the house facing the road, or a detached garage isn't covered by Class 1: get a section 5 declaration (€80) from the council first, and expect to apply for permission to make a detached garage somewhere to sleep or live.
