MyKiwiHouse is combining the best practises from Europe and New Zealand into a smart and sustainable design, which is cost efficient not only to build but also affordable to live in. A warm, dry, well ventilated and healthy home.
Certified to 8 Homestar Design rating. 8 Homestar is evidence of a superior design (Building Code requirements are 4 Homestar).
The result is a home with far superior heating savings (up to 90% better) than standard Building Code compliant houses. The entire envelope has a thermal performance which meets PHI Low Energy Building Standard, i.e. energy demand of no more than 27 kWh/m2a (in Queenstown Climate Zone) ¹
The house can be Passive House certified at an additional cost.
Each house is Blower Door Tested at completion to verify airtightness.
Consistent Quality: Built by leading New Zealand construction companies, using certified material and innovative wall panel technology.
The Swedish 3-glazed timber / aluminium windows and highly efficient ventilation system prevents problems with condensation and moisture.
