Cool Spaces

Kaiapoi, Canterbury

Who we are

CoolSpaces is led by sustainable house campaigner and environmental consultant Claudia Kaltenstadler. Claudia’s daughter, Elena Kaltenstadler, is a sustainable-design evangelist who also contributes her skills as a photographer and digital native.

About our builds

Together they work with international and national architects individually selected by Claudia. These architects are chosen for their ability, imagination, integrity and alignment with a commitment to homes that optimize joy, respect the value of space and walking gently on the earth, and honor enduring and thoughtfully-scaled design. They also stand behind everything they create. There’s quite a history to the company. As a new-comer to New Zealand in 2006, Claudia was taken aback by the lack of affordable, cost effective, energy efficient homes. It was something she wanted to change and has worked very hard to achieve. CoolSpaces is the result. For clients, Claudia is also the pivot-point, the safe pair of hands and sympathetic ear providing personal, efficient and thorough project liaison and process management, that takes clients from home wishing and dreaming, through design choice and crafting, to complete home realization.
