This Woodinville geodesic dome is Buckminster Fuller-approved

How many houses are signed by a famous architect and philosopher? Buckminster Fuller signed this geodesic home in Woodinville—making this geodesic dome approved by the the most famous innovator of geodesic domes.

That alone may be worth a tour. Even without it, the hemispherical house from 1979 is worth a look.

Thought went into working with the inevitable angles that define a geodesic dome. Easier to build than a truly hemispherical house, the triangular panels create confusion for some designers and opportunities for others.

Here, the angles frame a grand and broad entrance as well as pie slices of skylights in the ceiling. The interior walls are more rectangular. The hemispherical shape is great for energy efficiency, but the walls inside can be a bit more conventional.

Inside, find 2,240 square feet of living space split between the large first floor and the loft of a second floor. It holds three bedrooms and one and three quarter bathrooms that all show signs of the dome, with the bonus of a more traditional boxy sauna.

Downstairs, a country kitchen features blue tile counters and rural cabinetry, with a convenient dish rack over a large prep and serving counter.

The one-and-a-half-acre lot provides the space necessary for a fruit orchard, blueberry bushes, and even filbert trees. Nuts enough to keep the squirrels happy. A greenhouse supports more gardening projects. A shop is available, too, maybe something that’s handy for custom woodwork that can be necessary for a custom house.

The price for the signature plus the house plus the lot is $635,000. The fact that all three can be ever-present conversation starters is a bonus.
