The Welch family in Bellingham, Washington are getting used to their unique home attracting visitors who want to see its heat pump, water filtration system and other inner workings.
This home needs no city water but uses instead two large tanks which gather rainwater from the metal roof. The stored water is filtrated to be used for bathing, cooking, and even drinking. Furthermore, the Welch’s home has two bathrooms with composting toilets.
The family is still installing many more sustainable technologies, like solar panels.
The objective is to make the house a net-zero water and net-zero energy residence. And there’s so much advanced technology and design that the house recently won the “Best Building Science” award from Green Builder Media.
