Stellaria NZ

Our path to sustainability in New Zealand

We believe that every New Zealander deserves a healthy, warm, dry, and beautiful home; and we are crazy passionate about seeing our clients getting just that.
Seeing the current state of the majority of houses in New Zealand, we knew we had to be the change and here it is.
Cold & damp in winter with condensating windows. Hot & sweltering in summer, expanding & contracting – most NZ homes cannot cope with our changing climate. We wanted more than a 10-year master builder’s guarantee.
We had to find a solution.
Our journey took us all the way to Europe, where homes and buildings are warm/cool, strong, meet the utmost quality & performance levels and last many, many generations.
Having watched the evolution in building & design in New Zealand over the past 25 years, we know POROTHERM is the perfect building solution. One wall does it all…
See for yourself.
If you want to live exceptionally well in a healthier, 100% natural, permanent home that will truly last, then POROTHERM is for you – we love to talk about this, call us!
