Proof of Concept

The first Passive House was built in 1991 in Darmstadt, Germany.

The concept was developed in the 1980s by German professor Wolfgang Feist and Swedish professor Bo Adamson.

The Antiochia model consumes only 10.9 kWh per sqm per year. That’s about 5 times more efficient than a traditional house!

Tesla’s Solar Energy

We’ve integrated Tesla's solar energy technologies into our perfectly designed homes. Each roof is covered entirely in the company’s advanced solar tiles. We are also working to incorporate Tesla's powerful energy storage battery with a capacity of 4kW. As a result, your energy needs will be met under normal conditions day or night, summer or winter.

There will be incredible demand for this house, meaning it will be rented way faster and for a longer period than a conventional house.

Lifetime additional operating cost of a conventional house = $178.000


*Based on California energy prices. Excludes maintenance costs, meaning the true figure will be far higher. Calculated according to the Antiochia model.


Our designs extend so much further than aesthetics. As building scientists, we focus on the most critical aspects for your life and well-being, not only what’s easy to evaluate with the naked eye.


Attention! We understand there are many factors in your ear when purchasing a home. The voice of science speaks the truth — a larger upfront cost will save you far more in the long run while contributing meaningfully to the environment.
