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 Real Comparison
The same 117 m² home, built conventionally vs. as an EcoDomeHomes residence. Our Builder Grade tier runs about 5% below standard construction in Portugal and the US, with a 6 to 10x longer service life.
| Portugal · 117 m² home | Rate | Total |
|---|---|---|
| Conventional mid-range build | €1,800/m² typical | €210,600 |
| EcoDomeHomes · Builder Grade | 5% below standard construction | You save on the build · ~€21,000 |
| United States · 117 m² home (1,260 sq ft) | Rate | Total |
|---|---|---|
| Conventional stick-frame | $238/sq ft typical (NH/Northeast) | $299,880 |
| EcoDomeHomes · Builder Grade | $226/sq ft · 5% below standard construction | You save on the build · ~$30,000 |

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.
Yes, EcoDomeHomes residences are permitted, inspected, and insured like conventional homes. They qualify for standard residential mortgages in Portugal and the US. We can share our experience with specific lenders during your initial planning call.
Typical project deposit is 10% of the contract price, due on signature. This secures your slot in the build calendar 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.
