My history with America and healthy homesWord from founder of Positive homes, Laurent Heit

Originally, I am an electrical contractor in a wonderfull city called Strasbourg, France located in the center of Europe.

This place is well known for his century old tradition and Half timbered Homes. Which inspired me until now! Its been more than 10 years that I’ve been involved in creating more healthy homes.

In 2008, at 4AM in a gas station, I met a german Architect who was Electro-hypersensitive (EHS).

He explained me how bad he felt near electrical installation, cell towers or Wifi. I learned about it and helped people in my hometown to resolve this kind of issue… then the journey for the best sustainable and healthy home has begun !

I was studying how to design energy efficient house called Passive house in Germany, discovered new techniques and new building materials with CLT to lower CO2 emission and build modular.


At the same time I spend my holidays in the US and especially in California every.

After a few years holidays in the US, it became working on an holistic approach of eco-friendly homes.The more I spended time in California and in the US, more I feelt in love with this country. I was really feeling that I was belonging to California and the love story began.

Since that time I never stop looking for the best way to build the most sustainable and healthiest homes in the U.S!

Then came to life Positive homes...now it is your Story!
