We 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. 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.

As a holistic partner for all concerns and construction projects relating to building technology, we implement high-quality and optimized solutions in accordance with the wishes and goals of our customers. From simple heating system replacements to solar systems to complex installations, we are happy to assist you. Our solutions in the areas of heating, ventilation, air conditioning and solar collectors / photovoltaics are created in close cooperation with our sister companies (planning & engineering - s3 GmbH , execution - HSH AG ) and in constant contact with the client. This enables us to accompany you from decision-making through installation to system optimization and maintenance. Our transparent approach creates systems that are not only sustainable, but also mesh seamlessly and are in harmony with the needs of the users and residents of the building.
