What affects the cost of a garage conversion to living space
- Plumbing
- Adding a bathroom or kitchenette is the single biggest cost jump — often $10,000–$25,000 on its own depending on drain access.
- The garage-door wall
- Infilling the opening with a framed, insulated wall and window typically runs $2,000–$6,000 and transforms how 'converted' the space feels.
- Floor height & insulation
- Garage slabs sit lower than house floors and are rarely insulated — raising and insulating the floor adds cost but is what makes the room feel like part of the house.
- Heating & cooling
- Extending ducted HVAC is dearer than adding a ductless mini-split ($2,000–$5,000), which is the usual choice.
- Permits & code
- Habitable-space rules (ceiling height, egress, smoke alarms) vary by council/municipality — permitted conversions appraise and sell far better than unpermitted ones.

How to read these Ireland figures. The cost is the US national midrange benchmark adjusted by a Dublin, IE cost multiplier (1.08×) and shown in EUR. The “% recouped at resale” is a national (US-derived) Cost-vs-Value benchmark applied to the local cost — it is not a locally measured resale figure, and real recovery varies by Ireland market conditions.
