  • Your project has at least two units, the manufacturer's minimum.
  • You want panels that don't burn or absorb moisture.
  • You prefer to order the kit and import it yourself, with our support.

Frequently asked questions

Is a zome a dome?
Not quite. Both are round and faceted, but a zome is a zonohedron, with diamond-shaped faces, while a geodesic dome is divided into triangles. The Zome we offer is made of insulated panels, with no timber frame.
Which one costs less?
The dome has a closed final price, delivered and assembled, in the table above and in the configurator. The zome is on request, because shipping from California is calculated project by project. Ask for both and compare the final price.
Can I mix zomes and domes on the same plot?
Yes. Tell us how many of each and you'll get one quote for the whole project.
What is the lead time?
For the dome, 8 to 12 weeks from deposit to the assembled unit. For the zome, it depends on the manufacturer's production schedule: we confirm it with the quote.
