Te Whare o K&K

Te Whare o K&K is New Zealand’s most northern Passive House project by far. It’s one of only two north of Albany, at time of writing, and over 260km further north than Lower Saddle House.  It’s a paragon of good practice when it comes to Passive House design.

Tocker Residence

This beautiful home on an end section looks out over the river. It is very much a house of two halves, with the principal …

Leith Valley Passive House

New Zealand’s newest Passive House Plus is home to a couple—and their two electric cars. Their latest monthly power bill was about $50, of which fully $30 was line and other fixed charges.
