Germany has chosen to modernise its New York diplomatic tower without replacing it. The German House faces the United Nations and must respond to security, energy, access and workplace needs that have changed since it was built.
Sauerbruch Hutton and Studio Gang won the competition with a proposal that retains the structure and reorganises the facade, interiors and shared spaces.
Keeping concrete and steel avoids a substantial share of demolition emissions and waste. It also means accepting inherited spans, cores and heights that a new building could redraw.
