Sad news that Hardt-Waltherr Hämer, the father of ‘careful urban renewal’ (’behutsamen Stadterneuerung’) and director of the Altbau half of the IBA 1987, died on Thursday.
Hämer was a key plyer in the movement against the excesses of modernist planning of the 1960s and 70s, which in Berlin reached its nadir with the redevelopment of Kottbusser Tor in Kreuzberg. He took the (at the time radical) view that cities could be revived by retaining the existing built fabric and working with local residents to improve their own homes and environment. This stood firmly against the orthodoxy of the time – the scorched earth policy of urban renewal through large scale demolition and rebuilding, including major new road networks, which was of course much more profitable for investors and contractors than Hämer’s ’slow architecture’ approach.
His much publicised and successful project to put these ideas into practice at Chamissoplatz in Berlin’s Kreuzberg district led to his heading of the Altbau element of the International BauAustellung of the 1980s in West Berlin. The legacy of his work here was later to be largely ignored during the redevelopment of Berlin following the fall of the Wall, with rabid gentrification, displacement of long-standing communities and the general blandifying of large parts of the city.
