Cost to Build a Garage Calculator NZ for 2020 by Superior Renovations ®

In New Zealand, 92% of households have at least one vehicle according to One Roofs (2019) research so it’s not a surprise that most home buyers and renters are looking for property that has a garage. Does it actually add any value to the property? Not as much as people think but in short, it adds 2-3% to the sale price of the house – however it’s different for all locations (eg it will be perceived as more valuable in an area like Central Auckland, people are paying $50,000 to $75,000 just for a car park)
