Bay of Plenty – Whakamarama

eHaus Euro - Certified Passive House Classic

This 144m2 home is beautifully located in a rural lifestyle block in Whakamarama. With 3 bedrooms and 2 bathrooms, the family also enjoy the open plan living/dining area and library office to take in the landscape. The house has uPVC European engineered joinery and a hot water heat pump.

Minimal glazing on the western wall ensures that the house meets just 1% of the year above 25 degrees, in the sunny Bay, this kind of result is excellent.

This home is a delight to our European clients, who how enjoy the constant 18 degrees through the whole house without any heating required.
