The Stellaria Story...

It all started with a vision: the idea of a building with near-zero heating, cooling or ventilation required. People-focused with good air quality and comfortable indoor temperatures all year round. Now that vision has become a reality; the building is a promise.  

 

A Porotherm Clay Bock building promises excellent return on value, energy efficiency and life cycle costs. The promise is delivered exclusively by building physics; solid walls and ceilings that serve as insulation & thermal mass, giving you much more for your money. Constant feel-good temperatures mean good health and truly living well. There’s just no comparison.

Chris & Robyn MacPherson of MacPherson Architecture Ltd have been designing high-end homes for over 25 years. Frustrated by the overall poor quality of NZ building materials, poor performance and the minimal Level 3 most NZ homes are built to, with only a 10-year warranty on the biggest financial and emotional investment of a lifetime, they believe Porotherm clay block homes offer a long-awaited solution to a very long standing housing crisis.

Feeling is believing. When you walk in and close the door, you are in a world of your own. The difference is like night & day. It’s quiet, peaceful and fresh, 100% natural with interior lime plasters. There’s just nothing like it.

Seeing is believing. When you have a zero-degree frost outside and the thermometer shows you the temperature has not moved below 18 degrees inside with no heating from the night before. The promise has been kept…

The vision has become the reality.

 

The Stellaria-Wienerberger Story...

It all started with a passion. When Chris & Robyn first discovered Porotherm and saw instantly the simple but extraordinary power of one single extruded clay block - they knew they had found a far superior way to build. 

So they formed a partnership with Wienerberger in Europe and Stellaria NZ was born in 2014. Visiting Europe and living within these walls is an extraordinary experience. As most of Europe builds using this construction system, it’s the norm. There is no one way to truly describe how the walls make you feel: safe, peaceful, cocooned and wrapped up are just some of the ways to tell you.

 

Really, you have to get inside and feel the walls. You have to experience how the building makes you feel – then you just know…
So it began with the Porotherm Passion which has now become the Porotherm Promise but as Chris & Robyn soon discovered, Wienerberger has so much more…
