Designed to provide everything a small family wants, with an easy double-door connection to a southern garden. The large, covered south porch expands the house and can take the family outdoors for meals and play. In this compact house, privacy and quiet are achieved during the night by substantially separating the master suite from the smaller kids' rooms. Those kids' rooms are sized for a twin bed and a desk  and have a dedicated bathroom. Interestingly, the living room is designed to meet code as a walled-off bedroom if the house ever needed to become an aging-in-place home.

Building Plans FAQ

For what building materials are the plans designed?

The walls and roof are SIPs (structural insulated panels), stem walls are ICFs (insulated concrete forms), and we specify a concrete slab-on-grade atop 4” of foam. We specify triple-pane windows and insulated exterior doors. We always specify a heat pump as the heat source. We also always specify an HRV (heat recovery ventilator) to meet ventilation code and ensure great indoor air quality.

What is a zero-energy home anyway?

Net-zero-energy homes combine energy saving techniques with renewable energy generation so that they produce as much energy as they consume over the course of a year. These ultra-efficient homes usually add energy to the grid when the sun is out and take energy from the grid at night and during the winter, boasting a net zero-energy consumption on an annualized basis.

Can I get a refund?

After you purchase and download any plans, we do not offer a refund. However, our mission is to ensure that you have a successful new home build. If the plan you purchased exceeds your build budget, or you are unhappy in any way, we will exchange for a different plan for free. You may also upgrade to a higher tier of the same plan and pay only the difference.

Can you engineer the plans for my lot?

If you are building in the state of Washington, we can arrange for our professional engineer (PE) to run the calculations and stamp your planset. If you are in another state, we can direct you to an appropriate engineer, and if needed, we will help with the process. Learn more about our process.

Are these plans code compliant?

Each of our plans has been built at least once, and all are compliant with the latest iteration of the International  Residential Code (IRC), which most U.S. jurisdictions have adopted. 

What size should I print the plans?

We deliver our plans in PDF format, and they are designed to be printed on 36″ x 24″ sheets of paper. The resulting scale is ¼” = 1’.

What climate are these plans designed for?

All of our homes have been designed for the Northwest region (Climate Zones 2 & 3) to generate at least as much power as they consume on an annualized basis. If you plan to build outside of this zone, some modifications may be required. Please contact us for more information.
