About The Company
GROPYUS is a technology-based construction company focused on building multi-story residential buildings. Thanks to its prefabricated building system with a wide range of design options, automated offsite construction, and fully digitalized processes, the company is able to create resilient timber housing quickly and cost-effectively. GROPYUS is using scalable construction and manufacturing solutions to tap into a future market, strengthen Europe’s innovation capacity, and play a substantial role in improving sustainability. The company delivers its multi-family houses as a complete and turnkey solution. The combination of technology, construction, robotics, and manufacturing expertise means buildings can be created in a fully digitalized end-to-end process.
