Executive Management

Mathias Piazzi

“Our company enriches VIVIUS with practical expertise in the use of reclaimed and eco-friendly building materials. We experiment with new possibilities and breathe new life into forgotten building materials. Our collaboration with VIVIUS provides us with a valuable exchange with like-minded individuals who share our commitment to sustainability. To embed sustainability in the long term, we calculate the carbon footprint of every building component, prioritize reuse, and favor locally sourced materials.”

LokHaus+ is an innovative company with locations in Tisens and Lana, specializing in sustainable wood construction and renovations. Founded by experienced carpenters Mathias Piazzi and Martin Zuech, the company focuses on high-quality wood construction with an emphasis on sustainability and the circular economy. Among LokHaus+’s strengths are the design and construction of custom timber homes using the company’s proprietary Loksystem+, a wall system made from local wood that is virtually free of adhesives and plastic sheeting, ensuring optimal insulation and energy efficiency. In addition to traditional carpentry work, LokHaus+ offers sustainable renovations, wood-frame building additions, the fabrication of carports, facades, and other wooden structures, as well as professional sheet metal work. By reusing materials, the company actively contributes to the conservation of resources.
