Geodesic domeCan be orderedNatural Spaces Domes ↗

The Model 650 shell kit, a geodesic dome kit from Natural Spaces Domes, has no published price, is engineered to 200 mph wind and carries 150 psf of roof snow load.

Natural Spaces Domes does not publish anything about fire or a price for this model, so 69 percent of the fields we score are blank.

None of that tells you whether it works on your land. Wind, snow, seismic and flood performance are site specific engineering, so the only useful answer comes from running this kit against your address.

Completeness

31%

31 percent of the fields we score are backed by something Natural Spaces Domes published. Why completeness is never part of the grade.

The thing nobody else will tell you

This kit cannot be scored on its own. Nothing on this page tells you whether it works on your land.

Wind, snow, seismic and flood performance come from your address, not from this kit. Put in an address and the gates run against the real requirement at that point.

The Kit Home Finder Grade

Not ratedNot rated, which is the absence of a score rather than a bad one. We could not rate buyability, cost honesty or materials and carbon tier. This says nothing about how the kit performs. A maker can publish an excellent wind and snow rating and still be unrateable here, because this grade measures whether you can buy it, whether the price is honest, and what it is made of.

Rubric v1.0, August 2026. Site fit is not in this grade, because it depends on your land rather than on the kit. Every weight, and what we refuse to grade.

What the maker publishes

Everything here came off Natural Spaces Domes's own pages, cited at the bottom. A blank is a blank: we never fill one in.

What the maker says it resists

Design capability as published. Not a certification, not a rating of your house, and not proof against anything.

Engineered wind speed	200 mph
Roof snow capability	150 psf
Seismic	Company assigns all dome models an internal 'Zone E' earthquake-resistance classification; not tied to a published third-party seismic code zone or test standard.
Fire	Not published

Price

Not published

This maker publishes no price. That is the single most common gap in the Index, and it is the first thing to ask them.

What that number covers	Not published

What else we found

Published spec table lists 'Ultra-Lok wind load' of 150+ mph for the two smallest models (500, 625) and 200+ mph for Model 650 and larger; snow load is 100+ psf for the two smallest models and 150+ psf for 650 and larger. Company describes these as engineered 'minimum code loads' calculated without crediting the plywood panels' own structural contribution (a conservative engineering figure, not an independent lab test). Dedicated pricing pages exist (Shell Kit Costs) but list no dollar figures on the overview page, pricing is only shown after clicking into individual size/model pages, which were not reached.

Questions people ask about the Natural Spaces Domes Model 650 shell kit

Answered from what Natural Spaces Domes publishes, including the answers that are "they do not say".

How much does the Natural Spaces Domes Model 650 shell kit cost?

Natural Spaces Domes publishes no price for this model. Across the whole Index only about a third of makers publish a price in dollars at all.

What wind speed is the Natural Spaces Domes Model 650 shell kit engineered to?

Natural Spaces Domes publishes 200 mph for this model. That is their design capability at the conditions they assume, not a rating of your house. Your required design wind speed depends on your address, your Risk Category and your Exposure Category.

What snow load can the Natural Spaces Domes Model 650 shell kit roof take?

Natural Spaces Domes publishes 150 psf for this model. Check whether that is a ground snow load or a roof load, because they are different numbers and makers are not consistent about which one they quote.

Can you actually buy the Natural Spaces Domes Model 650 shell kit?

Yes. Natural Spaces Domes takes orders for this model today.

What foundation does the Natural Spaces Domes Model 650 shell kit need?

Natural Spaces Domes does not publish foundation options for this model. That matters more than it sounds: in a FEMA A or V flood zone the finished floor has to sit above the base flood elevation, and a kit offered on a slab only cannot get there.

How well does the Natural Spaces Domes Model 650 shell kit stand up to a hurricane or a wildfire?

The honest answer is what it resists, and under what conditions. No kit home is proof against either, and any page telling you otherwise is selling. "Hurricane rated" has no legal definition in the United States, no house can be tornado rated, and whole building certifications like LEED, Passive House and HERS all require a built, sited, inspected home and cannot be attached to a model from a spec sheet. What a maker can honestly tell you is what the design resists and under what conditions. For this model, that is a 200 mph design wind speed.

Will the Natural Spaces Domes Model 650 shell kit work on my land?

Nothing on any spec sheet can answer that, including this one. Wind, snow, seismic, flood and soil requirements come from your address, not from the kit. The Kit Home Finder runs every kit in the Index against the published hazard data for your point and shows you what survives and why the rest did not. It is free.

Compare

Nothing here is ranked by what anyone pays us, because no kit maker has ever paid for placement on this site.

How it compares

It documents more than the average geodesic dome kit, 31 percent against 30, and more than 8 of the other 16 we hold. Publishing a design wind speed puts it in the 41 percent of geodesic dome makers that do.

Computed across all 514 kit homes in the Index, 17 of them geodesic dome. Recomputed on every build.
