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

从1862年开始的具有约束力的柏林周边土地利用计划创造了一种结构，这种结构直到今天仍然是柏林市中心的特征。在规划史上，詹姆斯·霍布雷希特的计划是一个反复出现的(往往是负面的)参考。该计划在2012年获得批准150周年，但几乎没有受到关注，这是一个跨学科研究项目的理由。该项目的目的是考察该计划的思想历史及其实际历史。该项目包括(1)深入分析规划及其作为城市扩张框架的逻辑，(2)鉴于规划作为城市扩张框架的坚固性，对城市发展的可视化，以及(3)对由此产生的城市空间的文化、历史和艺术价值的审查。规划的价值、空间发展和实质的归属被概括为Hobrechtsches柏林(Hobrechtsches柏林)，以涵盖该主题的多维。这种复杂性也反映在形态城市分析与对愿景、社会欣赏和可比的欧洲城市扩张计划的相应检查的结合上，例如在巴黎、伦敦和巴塞罗那。这项研究项目的目的是获得关于柏林城市结构的新发现，并重新评价霍布瑞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思考。

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.
