What's included

Pro tip: Check what your market values more — extra living space or a garage. In car-dependent areas, keeping the garage can be worth more.

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.
