站在助力中国城市更新的出发点，KKL于2018年与北汽集团、北京市规划设计研究院合作，共同努力并主持了北京齿轮厂（北京定福庄国际传媒走廊核心区域）的改造规划研究工作，通过将已废弃的厂区与文创产业相结合，在保留原有厂区肌理与建筑结构的基础上进行重新规划与形象更新，为街区注入了新的血液与活力。

 Standing at the starting point of helping China's urban renewal, KKL worked with BAIC group and Beijing Institute of planning and design in 2018 to jointly work and preside over the transformation planning and research work of Beijing gear plant (the core area of Beijing Dingfuzhuang international media corridor), and combined the abandoned plant area with the cultural and creative industry, On the basis of retaining the original plant texture and building structure, the new planning and image updating are carried out, which infuses new blood and vitality into the block.

整个厂区建立于20世纪60年代初期，经过多年的使用、加建、改建后现已废弃，而作为整个城市街区中的核心片区，整个项目具有非常高的改造再利用的需求以及条件。由于本身功能性质所限及其与周边区域发展之间的不平衡，改造面临着各种尖锐的问题，主要有四个方面：1、厂区现状布局与区域道路规划之间的矛盾；2、厂区既有建筑空间尺度与新内容所需空间尺度之间的矛盾；3、厂区整体形象与周边社区形象之间的矛盾；4、厂区既有建筑权属与规模不清的问题。

The whole plant was established in the early 1960s, and has been abandoned after years of use, construction and reconstruction. As the core area of the whole urban block, the whole project has very high demand and conditions for reconstruction and reuse. Due to the limitation of its own functional nature and the imbalance between the development of its surrounding areas, the transformation faces various acute problems, which mainly includes four aspects: 1. The contradiction between the current layout of the plant and the planning of regional roads; 2. There is a contradiction between the existing building space scale and the space scale required by the new content in the plant area; 3. The contradiction between the overall image of the plant and the image of the surrounding community; 4. The existing building ownership and scale of the plant area are unclear.

为了有效的解决上述问题，KKL君从现状场地的研究和梳理入手，将既有建筑物进行分类，从建筑物的质量、历史价值、文化价值、改造难易程度等多方面入手，将既有建筑物分为拆除、保留更新（轮廓无变化）、保留改造（轮廓有变化）三类，同时通过对厂区及其周边社区之间的关系进行详细的研究后，在满足日照、界面等硬性要求的前提下增加一部分的新建指标，协调与平衡厂区更新所需要的多种要素。

In order to solve the above problems effectively, KKL classifies the existing buildings from the research and sorting of the current site. From the quality, historical value, cultural value and the degree of difficulty of reconstruction, the existing buildings are divided into three categories: demolition, reservation and renewal (no change in profile), and reserved transformation (changes in the outline), At the same time, after detailed research on the relationship between the plant and its surrounding communities, a part of new indicators are added on the premise of meeting the hard requirements of sunshine and interface, so as to coordinate and balance the various elements needed for plant renewal.

按照业主需求，厂区内除了将既有建筑通过改造利用为文创空间外，还需要根据区域周边配套设施的需求新建一栋停车楼与电影院，那么就需要对新建建筑与保留改造建筑之间的关系进行认真的研究。KKL君从城市整体空间关系的研究入手，通过多方案比较的手法对厂区总体布局方案做了仔细的推敲，认为在任何情况下，都需要最大程度的保留既有厂区整体的肌理，以继承其特有的文化属性，即保留与利用厂区内最具有符号性的厂房建筑，将新建建筑通过有机插入的手法融入园区整体环境，形成自身以及与周边环境相融合的形象。

According to the owner's requirements, in addition to transforming existing buildings into cultural and creative space, the plant area needs to build a new parking building and cinema according to the needs of supporting facilities around the area. Therefore, the relationship between the new building and the reserved reconstruction building needs to be studied carefully. KKL starting from the study of the overall spatial relationship of the city, carefully deliberated the overall layout plan of the plant area through the method of comparing multiple schemes. He thought that in any case, the overall texture of the existing plant area should be kept to the greatest extent to inherit its unique cultural attribute, namely, to retain and utilize the most symbolic plant buildings in the plant area, The new building is integrated into the whole environment of the park through organic insertion, forming an image of itself and the surrounding environment.

根据北京市对改造更新项目的要求，改造后的总建筑面积不得超过原有建筑面积，那么最直接的方式是完全遵循既有建筑物的轮廓与布局只进行外立面与室内空间的更新，但原本作为厂房的总体布局方式本身存在单一功能空间过大、功能布局过于平均、占地面积过大等问题，为了有效解决该难题，KKL君提出将场地内质量与历史价值不高且改造难度大的既有建筑物进行拆除，并将拆除部分的面积进行重新分配与整合，使功能更加集中高效，同时也可以利用拆除既有建筑之后的用地作为本项目乃至周边区域的活动广场，为整个城市片区提供多维度的室外使用空间。

According to the requirements of Beijing on the renovation and renewal project, the total building area after the transformation shall not exceed the original building area. The most direct way is to completely follow the outline and layout of existing buildings only to update the facade and interior space. However, the original overall layout of the plant itself has a single function space too large, and the function layout is too average In order to solve the problem effectively, KKL proposed to dismantle the existing buildings with low quality and historical value and difficult reconstruction, and redistribute and integrate the demolished area to make the function more centralized and efficient, At the same time, the land after the demolition of existing buildings can be used as the activity square of the project and surrounding areas, providing multi-dimensional outdoor space for the whole urban area.

整个设计过程的核心聚焦于对城市的关注，KKL君并不想简单的改造一个项目，而是更关心由此带来的城市空间的更新，这也正是在当前新的历史条件下中国城市发展的新目标，即逐渐从增量模式转为存量模式，城市更新正在成为城市发展的主要方式，也受到业内行业与机构的高度重视。

The core of the whole design process focuses on the attention to the city. KKL does not want to simply transform a project, but rather more about the renewal of urban space brought by it. This is exactly the new goal of urban development in China under the current new historical conditions, namely, gradually changing from incremental mode to stock model, and urban renewal is becoming the main way of urban development, Also by the industry and institutions of high attention.
