Klaus H. Ernst was a Berlin architect who worked on Modernist residential projects in Berlin-Kreuzberg. The catalogue holds 2 of his works, both in Berlin.
The Residential and Commercial Building on Kottbusser Straße and the Residential Complex at Skalitzer Straße were collaborative projects with Gerd Hänska, Hans Wolff-Grohmann, Bodo Fleischer, and Herbert Stranz. These buildings represent the large-scale Modernist housing that reshaped Kreuzberg's urban fabric in the post-war decades.
