Complex building engineering for
demanding projects

We at Kannewischer are consultants, developers, planners and implementers of complex building engineering. Our range of services covers the entire project process, from strategic conception to implementation, planning and construction management for innovative heating, ventilation, air conditioning, sanitation and pool water systems.
Sophisticated buildings and challenging technical problems  are what fascinate us. Since 1972, we have equipped more than 400 pool projects, numerous school buildings, laboratory and industrial buildings with the most modern HVAC, plumbing and/or pool water technology. Quality, resource efficiency, sustainability and economic efficiency are our top priorities. With the Kannewischer Group, we expand our knowledge of special buildings and realise both domestic and international projects.
