What BIOBUILDS clients say
Modern family home
“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
Family home, Germany
“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
Off-grid modular home
“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
From one family to yours.
BIOBUILDS was born from one man's mission to create the healthiest, most efficient home for his children. That same obsession drives every home we build today.
RIA Retreat
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.
