Till Cottage

This small Passive House north of Auckland is unassuming at first glance but is in fact a project of enormous significance. It is a retrofit, which is unusual enough, but it succeeds in reaching the full Passive House level of performance rather than the more flexible EnerPHit standard for retrofits.  The Passive House designer is proud of the fact that …

However, a new Passive House certified apartment block smack in the middle of the student housing precinct is a stark contrast.

The home is an outstanding example of meticulous planning and through project management, easily hitting all Passive House metrics with plenty of margin.
