The requirements of state-of-the-art buildings are changing. Dramatic increases in cost result in new structural concepts and, above all, in changing planning flows. Whether it is for a new building, a renovation or a conversion, with our buildings we always try to satisfy the different requirements. In order to achieve the highest standard in architecture and quality of life, we look for optimization potentials on all levels. Quality does not have to be expensive. Building and maintenance costs can be influenced significantly through diligent design. Therefore, we believe that architectural quality and economic efficiency need not contradict each other.
