eHaus Euro - Certified Passive House Classic - Multi Award Winning

Not only is this home the first certified Passive House for the Hawkes Bay but its also a multi Award winner. Taking not only Gold in the Master Builds 2020 awards, but also winning Category, Lifestyle for Sustainable Excellence and then the coveted Craftsmanship Award. This one a true reflection of Ian and Sharons reputation for excellence. A total of four awards in one night – that confirms what we already know about this home that its a star.

Set in a quiet cul-de-sac this four bedroom architecturally designed home has an ensuited master, two doubles, and single/office.  The main living space comprises of a modern slick kitchen and open plan dining/living areas, complete with large decks either side to provide that Hawke’s Bay indoor/outdoor living.

The Zender mechanical heat recovery system silently provides fresh filtered air 24/7 removing 98% of pollutants, while retaining the warmth. Keeping the house at a constant temperature all year round with no mould or condensation, giving you and the family the healthiest living space.

Beautiful wooden German designed high performing joinery have been used throughout, and together with the polished concrete floors gives a real wow factor to the overall interior look and feel.

Featuring lovely Cedar and BGC weatherboards contrasted with Schist the exterior of the home is quietly understated and very elegant.
