Built for fire, flood, wind, and time.
One structural standard, built to outperform conventional homes on every metric.
3-second gust wind resistance. Engineered design capacity to 400 km/h.
Multi-hour fire exposure rated. Survived wildfires that destroyed surrounding structures.
Magnitude seismic rated. Monolithic shell moves as one mass.
Flood and storm-surge resistant. Single-pour, joint-free continuous shell.
Shielded by a passive Faraday cage. Defence and data-centre grade.
Maximum burial depth. 2,000 PSF overburden, no load-bearing walls.
Spend once. Save for centuries.
A 500-year asset. Mortgage-eligible and insured like a conventional home, with value retained indefinitely. Over a 500-year life you reinvest the savings instead of paying for six to ten rebuilds.
How it compares to a conventional home.

From a family home to critical infrastructure.
The same airformed monolithic shell, engineered to one standard, across every sector we build for.
Disaster-proof greenhouses.
The same airformed shell, built for year-round growing. As an extension of your home or a stand-alone structure.
Connected to the home
A shell extension off your home, accessible from the kitchen. LED grow lights and automated venting grow herbs, vegetables, and citrus year-round.
Separate structure
A separate dome sized for a serious home garden or small market operation. Same climate system, same disaster resistance, same 500-year shell.
The questions everyone asks.
It depends on size, configuration, and finish. In Portugal, starting prices are €115k for the Family (80 m², 2-bed), €155k for the Coastal, and €275k for the Compound, with finished tiers shown in the pricing tool. You get a fixed-price quote within two weeks.
Our primary markets are Europe and the United States; builds elsewhere are by appointment. We evaluate your site as part of the design conversation and tell you honestly if it's a good fit.
Yes, 16 weeks from site-ready foundation to finished home. Design and engineering add about 4 weeks up front, and permitting varies by location. The build itself is the fast part.
Only if you want it to. The shell is the canvas and the finish is yours, from minimalist plaster to stone cladding to a traditional roof. Inside, they're conventional rooms with conventional finishes.
Yes. Our homes are permitted, inspected, and insured like any house, and qualify for standard residential mortgages in Portugal and the US.
They appreciate at the same rate or better than conventional homes nearby, with the lowest operating costs and longest service life of any home. The math is straightforward.
The first step is a free 30-minute build consultation about your site, your goals, and the configuration that fits.
