"Dreischeibenhaus"

The Thyssen House, also called the Three-Slab Building, is 94 meters high, has 29 stories and stands tall in downtown Düsseldorf. This striking office building was erected in 1959 on a skeleton frame with stiff gable panes and a consciously simple and clear curtain façade of stainless steel, aluminium and glass. After the previous general tenant relocated, new rental and marketing concepts were required. CANZLER ran an extensive building audit to identify the backlog in maintenance, need for energy optimization and modernization in order to upgrade the fit-out standard. Moreover, CANZLER examined converting the office areas for multi-tenant usage and turning tenant-specific fit-outs into flexible office properties. This included outlining surface area efficiencies for different office concepts, such as executive, combined and open-plan offices. The marketing concepts were flanked by a new fire protection concept that was implemented after consultation with the heritage protection authority and other agencies. Moreover, CANZLER examined whether the building could be achieve LEED or DGNB certification.
