Impulses For The City Of Tomorrow –

Berlin, November 3, 2025 – James Hobrecht shaped Berlin's urban development like few other figures. With his 1862 city plan, he laid the foundation for the compact, mixed-use city center that continues to define Berlin's character.

Equally groundbreaking was his contribution to the development of a modern sewage system, which enabled the city's rapid growth. As the city's chief engineer for road and bridge construction, Hobrecht also played a decisive role in shaping the city. In addition, he served for many years as chairman of the Architects' Association of Berlin (AIV).

To mark the 200th anniversary of his birth on December 31, 2025, the AIV is organizing a four-part series of lectures, panel discussions, and debates. The focus will be on both the historical appreciation of Hobrecht and his multifaceted work, and the question of what impetus his ideas can provide for Berlin's urban development in the 21st century. These events will focus on two main areas: the historical appreciation of Hobrecht and his multifaceted work, and the question of what impetus his ideas can offer for Berlin's urban development in the 21st century. On the occasion of his 200th birthday on December 31, 2025, the AIV is organizing a four-part series of lectures, panel discussions, and debates. 

“Hobrecht’s work is more relevant than ever: Dense, mixed-use urban districts and efficient infrastructure are once again key themes in urban development. We want to re-examine his ideas – critically, but also with a view to their potential for a sustainable future for Berlin,” said Dr.-Ing. Christian Müller, Chairman of the Board of the AIV (Association of German Architects and Engineers).

While Hobrecht was sharply criticized after World War I for the creation of what he called “the world’s largest tenement city,” the districts of the Hobrecht Plan are now experiencing a resurgence in appreciation. They are considered exemplary models of urban density, diverse uses, and a high-quality urban structure with streets and squares, which are gaining renewed relevance in light of climate change, housing needs, and the shift towards sustainable mobility.

Opening: November 27, 2025, 7:00 p.m.
