What Makes this home Green?

Welcome to this little homestead on the South Fork. Benny, owner of Confluence Building Co, and his family have lived here in the Saxon neighborhood for 8 years. After challenges buying in the area, they decided to write a letter to the owners of a neighboring parcel to where they were living at the time.

They purchased these 40 acres in April of 2021. A well was drilled that summer, a yurt was constructed on the property in the fall, built out during that winter, and the family moved onto the property in May of 2022. Design for the main house began in February of 2025, ground was broken when the permit was stamped in early August of 2025. For Benny, the ability to collaborate on the design and have a say in so many of the details was a dream come true for him as a builder.

This house was designed and built with the pretty good house principles in mind. Benny is of the belief that when building passive houses, what actually makes it green is lost and instead folks hyper focus on air tightness and using very expensive and specific materials coming from faraway places instead of using materials that are available regionally. Of course, there are all different levers that can be pulled during the course of a design and build but it is important to step back and think.

Two other aspects that makes this project worth sharing are the community that supported it and helped make it happen, and the unique and complex design with simple details. In Benny’s words, “The green building community tends to reinvent the wheel every time we build a new house or come up with a new wall assembly, and I think it would behoove many and save clients and builder money and headaches, if we simplified some of our approaches.”

Features

Site

First and foremost, the size was a key factor in making this a green build. Balancing as functional use of a space as possible while also not having it feel too small or too grandiose.

The other is the use of readily available common-sense materials. They tried to use things off the shelf and also tried to design the house in such a way to future proof it and be kind to the next person that has to work on it. From the trim details at the windows to the fact that there are no interior structural walls, making the whole house ready to be modified on the inside without having to reconfigure any structural elements.

Energy

R6.3 Rockwool comfortboard continuous exterior insulation throughout. It is also built nice and tight without spending loads of time, energy and resources to make it so very tight.

Water Efficiency

Low-flow fixtures.

Accessibility

Uneven ground can be expected.

4 Stairs to get onto the first-floor level.

Materials & Resources

If you had a venn diagram with 3 circles and those 3 circles were cost effective, local, and low global warming potential, my goal throughout was to balance those 3 factors and ideally find materials that checked all 3 of those boxes.

There was significant reuse of materials on this site:

  • All of the cabinets were reused from Second Use Salvage Materials out of Seattle.
  • Both of the bathroom vanities were reused.
  • The counter tops in kitchen and the bathrooms were all salvaged from Second Use.
  • Both of the bathroom sinks were salvaged.
  • Most of the light fixtures were reused.
  • All of the interior paint was salvaged.
  • Rigid foam in the roof assembly was from deconstruction Dave.
  • All of the LVLs in the floor system, which was roughly 360 Linear Feet of LVL, was salvaged from deconstruction Dave.
Indoor Air Quality

The heating and cooling system is a ducted mini split. One of the reasons for the ducted mini split is that the house has a wood burning stove.

That wood burning stove is undersized by design, so that the duct system can move that warm air throughout the house.

The house has an ERV for filtration. The house has a vent hood for cooking fumes and bath fans for humidity and odor control in both bathrooms.

Certifications

N/a.

Parking

There is ample parking on the field adjacent to the house.
