I have as many questions as answers unfortunately, but it will at least get us started. First of all, where exactly are you located in relation to Vancouver? Prices will vary a lot by region so it's very difficult to pin down a cost for you, you're better to get even a ballpark from individual builders. We don't have a list of regional builders for you unfortunately, but if you aren't too far out of Vancouver I would recommend looking into a Vancouver company called Lane Fab Design Build, even if they aren't close enough to build it for you they can help you with design, and possibly supply you with prefab walls as well, maybe even give you the name of another suitable builder if you're out of their range.
And are you looking just to build to a Net Zero standard or to get it certified? If so here is the Canadian Home Builders Association page on their Net Zero program, they may also be a resource to help you find a builder. I didn't want to leave you hanging too long without an answer, but I have a few lines out asking for more information for you, hopefully I will be able to add more to this soon.
What options are there for pre fab Passive House kit designs?
We will have more providers of kit houses soon, and there is a sign up on that page for more info on prefab kit homes, with that you would get a notice as soon as we have more to offer. Hope that helps!
Where can I find qualified green builders/modular or prefab homes in Port Townsend WA?
Hi Alyne, We have a number of prefab modular Kit houses that can meet LEED or Passive House performance standards here on this page -
We can't get you one right way in Washington but we are hoping to be able to supply energy efficient prefab houses to the West Coast in US and Canada in the near future. If you fill out the 'request a quote' form that can be found on each different model you can get more info on particular house designs, and we will be able to send you an email when there are some available in your region. How soon are you building?
