Garden room costs: what you'll pay and what it costs to run
The short answer
Garden rooms in Ireland typically cost €700 to €1,500 per m² for a catalogue room supplied and installed, or €1,800 to €3,200 per m² for a bespoke builder-built room. Foundations, electrics and heating are often extra, so set aside about €5,000 for those. A 32 to 45 m² garden home starts from about €50,000 for a modular unit.
