Frequently asked questions
How much does a garden room cost in Ireland?+
Our 25 m² ICF garden room, the Garden Studio, is €69,000 + VAT at 13.5% (€78,315 incl. 13.5% VAT), as a fixed price including design, build and full project management. Site works, connections and professional fees are excluded and quoted after your free site visit.
Can you live or sleep in a garden room?+
Not without planning permission. It is for use with your home — an office, studio, gym or hobby room — and cannot be lived in or slept in without planning permission. If someone is going to live in the garden, a detached garden home of 32–45 m² can be exempt under S.I. No. 340/2026 (Class 3A) instead: our smallest is the 33 m² 1 Bed Granny Flat at €93,900 + VAT (€106,577 incl. 13.5% VAT).
Does the Garden Studio need planning permission?+
No, as a garden room or home office. Garden structures behind your house need no planning permission if, together with any existing sheds, they total no more than 30 m², leave at least 25 m² of garden, and stay under 3 m high (4 m with a tiled or slated pitched roof). It is for use with your home — an office, studio, gym or hobby room — and cannot be lived in or slept in without planning permission. Using it as a home needs standard planning permission, which we can handle. We confirm the right route for your site at your free site visit.
How long does it take to build?+
The on-site structural build takes 5–10 days once foundations are ready. Design and connections come before that — we project manage the whole sequence. As a Class 3 garden room it needs no Class 3A notification.
What standard is it built to?+
The same ICF wall as our homes: a reinforced concrete core with continuous insulation on both sides, built by Primestructures' own crew. We confirm the specification for how you will use it — office, studio or gym — at your free site visit.
