What a garden room costs for your size
Two taps: the kind of build and roughly how big. The answer is a published Wicklow or Irish price for that size.
Published price for your size
€13,560
Loghouse.ie's published price for a 4 m × 4 m room, the nearest listed size to yours approximate, VAT not stated. Foundations, the electrical connection and painting are listed as extras.
- A ground screw foundation is from €90 to €110 a m² (Loghouse.ie).
- Power from the house is from €15 a metre of cable (Loghouse.ie), and it has to be done by a Registered Electrical Contractor (CRU).
- Avant Money's national guide gives €13,500 to €17,500 for a medium room, 4 m × 4 m to 5 m × 5 m.
How this is worked out
Timber cabin: Loghouse.ie's listed price for that size, or the nearest listed size where the answer says so; at 12 m², where none is listed, the area times their brochure rate of €900 to €1,200 a m² for smaller rooms. Insulated rooms: East Coast Carpentry's own price for that size, VAT, delivery and installation included. The multiplication is ours. Prices read on 3 November 2026. It's an estimate, never a quote.

Modular homes are a different thing
A garden room under Class 3 can't be lived in (S.I. 338 of 2026). A modular unit someone sleeps in falls under the new detached auxiliary dwelling exemption: 32 to 45 m², linked to the house's services, with 14 days' notice to the council, and those provisions run to 31 December 2030 (Fieldfisher). Wicklow County Council has its own section 5 form for it. That's a home, with its own rules, not a garden room.

Before you choose a spot
- Measure the garden. At least 25 m² of it has to stay open for the room to be exempt.
- Check how far the spot is from the house: the power cable runs that distance, and it's priced separately.
- Look at side access. Panels and a base have to get through.
- On a sloping hillside garden, ask about the base before anything else.

FAQ
Questions people ask
Is a prefab garden room cheaper?
A cabin from a price list costs least: Loghouse.ie's 3 m × 2 m room is from €6,720. It isn't insulated and wired like a fitted room.
Can I put up a flat pack garden room myself?
Many people do with a helper. The base has to be level and square first, and the electrics must be done by a Registered Electrical Contractor.
Does a modular garden room need planning?
Same rules as any garden room: Class 3, up to 30 m² in total and not lived in (S.I. 338 of 2026).
