Seattle Passive House – First you dig a big hole, then you fill it up!

The folks from Cornerstone Construction came out to start the dirt work and dug one fine hole – complete with an extra deep portion under the front of the house where the Geotech Engineer determined that extra structural fill was going to be necessary.  Unfortunately the original assessment of 2 – 2.5 feet ended up being 4.5 feet.   Dan was able to re-direct some of the excavated topsoil (sandy & some clay) to someone on Craigslist.  The remaining clay soil was hauled away.

Today was spent on the workshop footing.  This part of the build will not have the foam under the footing like the rest of the foundation since it is an unheated workspace and there was not a concern for a thermal bridge.  The plans for the rest of the house are designed such that the heat from the house will not escape into the workshop and exit through the foundation.

As we progress through this build the Passive House features will be highlighted and explained.  Dan, who is building this project as a homeowner and not through his construction company, would love to answer any questions that you have.  I would be willing to focus on special interest areas if anyone wants a particular feature detailed with pictures.  Please post any questions or suggestions in the comments section.  If you would like to be notified of future additions to this blog, there is a sign up link on the right side of the page.

  1. Hi Linda,

    Add more about the foundation plan if possible. Were all interested.

    • Hi Albert,

      Thanks for bringing that up. I intend to get into more detail next week as the foam goes in for the insulated slab complete with pictures and details from the drawings. Dan is going to provide me with some Therm files that I can screen capture and post too. Anything that is particularly important to Passive House construction will be covered in a lot more detail. Please be sure to ask if there is a specific area or picture that you want to see covered. By the way, I notice that even though the pictures are small on the blog, you can click on them for a larger view.
