The headquarters of the Kreditanstalt für Wiederaufbau (KfW) was built in the late 1960s as a group of office towers in Frankfurt’s Westend.In recent times, the building was starting to look somewhat down at heel and therefore the owner decided that it needed to undergo radical modernisation – only the load-bearing framework from the original building remained intact. This enabled the provision of daylight, fresh air, heat and cooling to be considerably improved and, above all, to be carried out in a much more energy-efficient way.
