A 9-foot upper level inside the dome, adds usable living area at roughly one-third the cost per m² of new construction, since the shell and foundation are already built.
Costs vary by labor and material rates in different regions.
Add a year-round growing space, same airformed shell technology, with LED grow lights and automated climate control included.

The look of the shell from outside. Some finishes also include a faux roofline that gives the home a more traditional silhouette.
Common upgrades, installed and coordinated as part of your build.
The Real Comparison
The same 1,260 sq ft home, built conventionally vs. as an EcoDomeHomes residence. Our Builder Grade tier is targeted to come in 5 to 10% below standard market rates, and is designed for a 6 to 10x longer service life.
| United States · 1,260 sq ft home | Rate | Total |
|---|---|---|
| Conventional stick-frame | $238/sq ft typical (NH/Northeast) | $299,880 |
| EcoDomeHomes · Builder Grade | 5 to 10% below standard market rates (target) | Target build saving · ~$15,000 to $30,000 |
The Compounding Math
Side by Side
How the three build levels compare. Starting prices come from the estimator above at each configuration's minimum size; use it for a price on your own home. Prices exclude taxes.

The questions everyone asks first.
It's directionally accurate, based on the same cost model we use to scope real projects. The ±15% range reflects normal variance for site conditions, regulatory differences, and finish selections. Once we evaluate your site and confirm your specifications, you receive a fixed-price written quote that doesn't change.
The estimate covers everything from architectural design through final inspection of the build level you select. Not included: land purchase, regulatory fees specific to your jurisdiction (permits vary widely), landscaping outside the immediate site footprint, and connection to municipal utilities if not on-site.
Three reasons: labor rates differ significantly between Portugal, broader EU, and the US; some materials are more expensive to source outside our Portuguese supply chain; and regulatory compliance varies (US code is more involved than EU code in several respects). Portugal is the baseline because our supply chain is fully domestic here.
EcoDomeHomes residences are designed to meet local building code so they can be permitted, inspected and financed like a conventional home. Approval, insurance and lending decisions rest with your municipality, insurer and lender.
Typical project deposit is 10% of the contract price, due on signature. This secures your place in the project schedule and funds the design and engineering phase. Subsequent payments are tied to construction milestones.
The calculator covers about 80% of typical projects. For larger compounds, unusual site conditions, fully custom architecture, or commercial-adjacent residential (e.g., a home with an attached agricultural structure), request a tailored quote, we'll respond within one business day.
