BIOBUILDS was born from a father's desire to build the best home for his family. Today, that vision guides us to innovate radically and build the future of living.
RIA, the most efficient prefab house in the world, recognized globally. With a consumption of only 2 kWh/m² per year. It was our first concept to demonstrate that speed, efficiency, sustainability and health can coexist.


The first street of passive houses, with a consumption of only 12 kWh/m² per year (28x more efficient than average). Built using prefab panels with straw insulation. Nearly zero bills and thousands of tons of CO2 saved using healthy, organic materials.
"We wanted a modern home that would stay affordable long term. With BioBuilds everything was simple and straightforward, and the result exceeds what we imagined. Bills are very low and the atmosphere truly makes you feel at home."
- Merticariu family, Romania
"We started with a single 24 m² module, but the quality and efficiency exceeded every expectation. So we decided to replace all our offices with modular units. Next we plan to expand with more modules as the business grows."
- Adi R., Director, Arox Equipment
"We were initially intrigued by the Passivhaus standard, but the real-world performance was much more interesting. Our first heating bill for December was around €20. In our old apartment we would have paid about €250. The quality is truly next level."
- Helena S., Bavaria, Germany
"As an entrepreneur building in the Carpathians I was facing delays and rising costs. Looking for a solution I found BIOBUILDS, and in under a month I had a fully functional passive house."
- Adrian, Owner, Porumbacu Garden
"Moving into Modular radically changed our lifestyle. We got so used to the clean air and natural feel that we cannot imagine going back to a normal house."
- Toma family, Romania
"As two software engineers, the idea of supervising a construction site for over a year was our biggest nightmare. BIOBUILDS was the perfect fit. Their process felt like a well executed project plan with clear stages and a fixed deadline. It let us get the life we wanted without derailing our careers."
- Alex P., Bulgaria
