Mini Dome

A hyper efficient tiny home in Portland, Oregon.

I designed, permitted, and built this mini geodesic dome in my backyard as an accessory structure. I operate it as a short term rental and I offer the hubs, plans, and construction drawings for sale.

The design incorporates modern building science best practices, can thrive in any climate, and will outlast you and I. The entire build process was meticulously documented and is published for free on the official website.
