Every Aro is the same home: five bedrooms, three baths, 2,715 square feet, designed by Olson Kundig and engineered to produce more energy than it uses. What changes is the street it sits on.
Aro does not build custom homes. It builds one home, then builds it again. Every home below shares the same plan, the same materials and the same systems, which is why the details on this page are true of all of them.
Every Aro home is designed by Olson Kundig, a practice known for thoughtful, human-centric homes that connect the people inside to the environment outside.
Because there is one plan, every decision in it was made with care and then kept. Sight lines, acoustics, where light lands in the morning, how the stair opens to the second floor. None of it is left to a builder's default.


Plan orientation is mirrored on some lots to suit the site. Room dimensions are on the plan.
The home is built as ten volumetric modules in Aro's West Sacramento facility, trucked to the lot and set by crane onto a finished foundation. Because the plan never changes, the modules are engineered once and built with up to 4x more precise tolerances than a site-built home.

Higher-grade materials than the average new home, chosen once for durability, low maintenance and how they age. Every home gets the same list. There is no upgrade tier.
Every Aro home comes standard with best-in-class systems for energy, comfort and peace of mind. No upgrades required.
Every Aro home uses a SPAN smart electrical panel to monitor and manage your electrical load, control every circuit from your smartphone, and integrate with the solar array to optimize energy use.
Standard in every homeMost homes are net contributors to carbon emissions. Residential housing is responsible for 23% of global emissions. An Aro home turns that around by producing more power than it consumes.
Metric tons of CO2 per year. Existing home 20 MT, new code-compliant home 10 MT, Aro home negative 0.3 MT.
Awards usually go to one-off houses. These went to a home that has been built dozens of times.

Open houses run most weekends across the Bay Area. If you already own the lot, a Build an Aro contract starts at $1,550,000 plus permitting and includes everything through move-in.
