Legacy Project 

The idea of multi-generational living became the starting point for the Legacy Project. Family comes first is the basis of this build. There are three sets of clients made up of active parents and the growing families of their two children. They want to live in their own houses that also allow for daily interaction. Their brief is to build four apartments on a 650sqm site which includes a rental unit.

Fairfield Office 

It may be small at only 55m2, but there are many things we love about our wee office. We always wanted to create not just a space to take work away from the “home office” but a space that would be open, welcoming, interesting and showcase some of the things we love, like SIP’s, timber and simply showing practically the benefits of building Better Homes.

Opening times
Friday 25th: not open
Saturday 26th: 10am – 4pm flexible but please pre-book
Sunday 27th: 10am – 4pm flexible but please pre-book

Address: 87 Middle Renwick Road, Blenheim

What is a passive house? 
Established in Germany by the PassivHaus Institute in 1996, "passive house" was one of the pioneering concepts for building low-energy houses and is still a leading building standard for energy-efficient houses to this date. Passive House design focuses on making the best use of sunshine, shading, and ventilation- rather than active heating and cooling systems such as air conditioning and centralized heating. Combined with high levels of insulation and airtightness, this makes it possible for a passive home to approximately 90% less energy than a typical home.
