Value and Making of Hobrecht's Berlin. Growth, change and heritage of the Berlin city expansion

自1862年起，柏林周边地区的土地使用规划创造了一种结构，这种结构至今仍是内城的特征。在规划历史上，詹姆斯·霍布雷希特的计划是一个反复出现的（通常是负面的）参考。2012年是该计划获得批准的150周年纪念日，但很少受到关注，这是一个跨学科研究项目的原因。该项目的目的是检查该计划的想法的历史和它的实际历史。该项目包括（1）对规划及其作为城市扩展框架的逻辑进行深入分析，（2）鉴于规划作为城市扩展框架的坚固性，对城市发展进行可视化，（3）对由此产生的城市空间的文化，历史和艺术价值进行审查。该规划的空间发展和实质内容概括为“霍布雷希特的柏林”（霍布雷希特的柏林）一词，以涵盖该主题的多维性。这种复杂性也反映在城市形态分析与相应的愿景检查，社会评价和可比的欧洲城市扩展计划，例如在巴黎，伦敦和巴塞罗那相结合。该研究项目的目的是获得关于柏林城市结构的新发现，并重新评估霍布雷希特对城市规划和城市发展的贡献。此外，该研究项目丰富了当前关于欧洲城市及其共同遗产的辩论，并鼓励进一步的批判性反思。

The binding land-use plan for the surroundings of Berlin from 1862 created a structure which characterizes the inner city up to today. In planning history James Hobrecht's plan is a recurring (often negative) reference. The 150th anniversary of the plan's approval in 2012, which received only little attention, is reason for a cross-disciplinary research project. Aim of the project is to examine the history of the plan's ideas and its actual history. The project includes (1) a deepened analysis of the plan and its logic as a framework for city expansion, (2) a visualization of the urban development in view of the plan's sturdiness as a framework for city expansion and (3) an examination of the cultural, historic and artistic value of the resulting urban space.Ascriptions of value, spatial development and substance of the plan are summarized by the term 'Hobrechtsches Berlin' (Hobrecht's Berlin) in order to cover the multidimensionality of the subject. This complexity is also reflected by the combination of morphological urban-analyses with corresponding examinations of visions, societal appreciation and comparable European city expansion plans, for example in Paris, London and Barcelona. The aim of this research project is to acquire new findings on the structure of the city of Berlin and to reappraise Hobrecht's contribution to city planning and urban development. In addition, the research project enriches current debates on the European City and their common heritage and encourages further critical reflection.
