In the cities of countries that have undergone rapid population growth and dynamic development, two phenomena attributable to market failure prevent sustainable urban renewal and reconfiguration. The tragedy of the commons and the tragedy of the anticommons. This article focuses on how the coexistence of commons and anticommons is designed on a specific example in a narrow perspective. In the selected sample area, the Fikirtepe Urban Renewal Project (Istanbul, Turkey), plan decisions (plan notes) that stimulate densification for land assembly were analyzed. This study aims to examine a large-scale and holistic urban renewal project that includes using plan notes to eliminate a co-existence of the commons and the anticommons. Semi-structured interviews with were carried out with 17 people who represent different key actors in the Fikirtepe Urban Renewal Project. The findings demonstrate that there are some conditions to implement this method for a holistic urban renewal project. The first is that the state (central or local governments) needs to be initially involved in this form of urban renewal project. Second, it is needed to defined the organizational structure and roles at the beginning. Third, increase of the legal power of the plan notes is needed. Fourth, ensuring legal certainty for all sides is needed in the land assembly stage.

在人口快速增长和动态发展的国家的城市中，由于市场失灵引起的两种现象阻碍了可持续的城市更新和结构调整。公地的悲剧和反公地的悲剧。本文重点介绍如何在狭义的角度针对特定示例设计公共和反公共共存。在选定的样本地区，Fikirtepe城市更新项目（土耳其伊斯坦布尔），分析了促进土地集约致密化的计划决定（计划说明）。这项研究旨在研究一个大规模的整体城市更新项目，其中包括使用计划说明来消除公地和反公地的共存。与代表Fikirtepe城市更新项目中不同主要角色的17人进行了半结构化访谈。调查结果表明，对于整体的城市更​​新项目，有一些条件可以实施此方法。首先是国家（中央或地方政府）需要首先参与这种形式的城市更新项目。其次，需要在开始时定义组织结构和角色。第三，需要增加计划说明的法律效力。第四，在土地集结阶段需要确保各方的法律确定性。首先是国家（中央或地方政府）需要首先参与这种形式的城市更新项目。其次，需要在开始时定义组织结构和角色。第三，需要增加计划说明的法律效力。第四，在土地集结阶段需要确保各方的法律确定性。首先是国家（中央或地方政府）需要首先参与这种形式的城市更新项目。其次，需要在开始时定义组织结构和角色。第三，需要增加计划说明的法律效力。第四，在土地集结阶段需要确保各方的法律确定性。
