在中国的新兴城市里，典型街区的大小约为 500×500 平方米以上。大型街区的问题主要存在于两方面：1、反城市——它减少了建筑/社区与城市之间的互动； 、高碳排放——公共交通不进入街区，城市空间又不宜于步行，使城市交通以小汽车为主导。

这个观察表明，致力于减少碳排放可能会成为提高城市宜居性的一种尝试，进而激发出一种温和的、潜在有效的设计策略：缩小街区的尺度。

The size of the typical block in new Chinese cities starts from approximately 500×500 square meters. The problem of the mega block is two-fold: 1. It is anti-urban – it weakens the interaction between buildings/communities and the city; 2. It is high-carbon – it makes an automobile-oriented city where public transportations stop outside the block and its scale does not support walking.

This observation suggests that the effort to reduce carbon emission could become an attempt to increase urbanity, which in turn inspires a modest, potentially effective, design strategy: Reduce the size of the block.

当非常建筑有机会在上海的嘉定设计工业 4.0 示范基地——一个办公园区时，我们将面临挑战定义为：首要的问题：典型办公园区是郊区式的，我们如何能使其更城市化？城市空间的品质是什么？如何让人们更多地使用和享受城市空间？具体的，我们聚焦于一个问题：一个街区能有多小？

我们认识到：密度、比例和功能决定了一个街区的大小。由街道划分的街区是城市肌理的一部分。

When Atelier FCJZ was given the opportunity to design an office park outside of Shanghai in the satellite town of Jiading, the Industry 4.0 Demonstration Base, we defined the challenge as following: The bigger questions: An office park is typically suburban, can we turn it more urban? What are the qualities of urban space? How to make the people use and enjoy them more? Furthermore, we focused on one specific question:How small can a block be?

The size of a block is determined by density, scale, and program. A block is part of the urban fabric and defined by streets.

在我们提出的总体规划中，通过低层数（4 层），高密度（平均总体规划容积率 1.2 /街区容积率 2）平铺和混合功能，来提高城市的便捷性：这些建筑主要为高科技公司办公，一层为公共/商业设施，居住部分（由于中国的功能分区法规中要求工业园内只能有租赁公寓和酒店，而不能有公寓）在顶层。

In the master plan we propose, urban accessibility is improved by a low-rise (4 stories) high density (average master plan FAR 1.2 / block FAR 2) carpet and mixed programs: Mainly offices for high-tech companies with public/ commercial facilities on the street level and some residential elements (rental apartments and hotels but not condominiums due to Chinese zoning regulation) on the top floor.

这里的主要城市空间是街道，街道宽 10 米，由两侧建筑 1 层高、3 米宽的骑楼（有顶步行道）界定。由于该项目位于长江以南地区，骑楼可以在漫长的雨季和夏季阳光灼热时为行人提供方便。

The primary urban space here is the street, which is 10 meters wide and spatially defined by the 3-meter wide covered walkways on the ground level of the buildings on both sides. As the project is situated in the southern Yangtze River region, covered walkways protect pedestrians from long rainy season and excessive sun in the summer.

考虑到每家公司将拥有上限为 4000 平方米的建筑，零售店和餐饮希望位于街角位置，便于步行及街区之间的连接性，以及创造尽可能多的建筑街道界面，我们将街区的大小设置为 41.2 x 41.2 米。

After considering the facts that each company will own the building up to 4,000 square meters, retail outlets and eateries would desire corner locations, walk-ability and connectivity between blocks, and more building-street interface in general, we set the block size at 41.2 x 41.2 meters.

网格：街道中心之间相距大约为 50 米 x 50 米。

街区/建筑模数：将41.2米分解为5个8米的柱距，两端再各有0.6米用于建筑外立面处理。41.2 x 41.2 米也符合每座建筑 4000 平方米的容积率，该面积允许若干小公司或一家大公司占用一个街区。这是一个单栋建筑的街区。虽然所有的建筑大小相似，但每个建筑的平面和立面设计都不同，这使得此开发项目能够满足不同企业的空间和身份的需求，并丰富了城市空间的体验。

Grid: Approximately 50 meters x 50 meters from street center to street center.

Block/Building module: 41.2 meters break down to 5 x 8-meter column-to-column bays plus 0.6 meter on each end for potential architectural articulation of facade. 41.2 x 41.2 meter meets the floor area ratio of 4,000 square meters per block thus to allow a block to be occupied by a number of small firms or one large company. It is a single-building block. While all the buildings are of similar sizes, each one is designed differently in terms of floor plans and elevations, which allows the development to meet the varied space as well as identity needs of the businesses and enriches the experience in the urban spaces.

最早建成的 4 个街区：当我们开始第一组 4 个街区的建筑设计时，我们首先布置了一系列公共功能，比如会议中心和酒店，其面积需求构成一栋 8 层的建筑。为了忠实于我们的总体规划，我们设计了两组独立的建筑：一组是四栋地面上 4 层的街区建筑；另一组是 4 层的环形建筑，“漂浮”在街区建筑之上。

这说明，微型街区有可能实现更高的密度。

First 4 blocks: When we started the architectural design of the first four blocks, we were asked to facilitate a number of public functions, such as a convention center and a hotel, which result in a 8-story buildings. To be true to our master plan, we designed two separate pieces of architecture: One is four 4-story block-buildings on the ground; another is 4-story continuous loop-building that “floats” on the top of the blocks.

This is an indication that the mini block may work for a higher density.

非常建筑设计了 22 栋街区建筑。41.2 街区与典型的 500 米以上街区截然相反（超大街区可达到 800×800 米），它是一个微型街区。

There are 22 block-buildings designed by FCJZ. The 41.2 block is the antithesis of the typical 500-meter and up mega block (Super mega block would go up to 800×800 meters). It’s the Mini Block.

总计划的概念通过以下几项措施得到加强：综合交通：在规划一系列步行街的同时，我们在一些次要的交通流线中引入了“共享街道”的概念，将街道生活和车辆交通结合起来，同时实现了安全性和便捷性。该设计最终没有能够完全实现。

The master plan concept is reinforced by several other measures:Integrated circulation:While planning a series of pedestrian streets, we introduced to some of secondary circulatory routes the concept of “Shared Street” to mix street life and vehicular traffic through careful design to achieve safety and accessibility at the same time. Unfortunately, this idea was not fully realized.

骑楼系统：在街道部分中已经提到，街道两侧的所有建筑都必须有 3 米宽的柱廊或悬挑，此要求在设计导则中有明确规定。

Covered walkway system: Already mentioned with the street, a 3-meter wide colonnade or cantilever is required on the street level for all the buildings, as specified in the design guidelines.

Building envelope: Setback is not permitted from the second floor and up, also as specified in the design guidelines.

在中国，通常的控制性规划没有定义建筑物的具体位置和形状，因此无法控制城市空间的质量。我们制定了介于总体规划和建筑设计之间的一套设计导则，作为规划实施的重要工具。因此，其他参与该项目的设计院/事务所也都必须遵循了这一设计导则。

项目完成后，我们相信：小就是美。

The conventional master plan for control in China does not define the specific locations and configurations of buildings and as a result it does not control the quality of urban spaces. We developed design guidelines between the stages of master plan design and architectural design as a critical tool for implementation. Therefore, other design institutes/offices participating in the project have all followed the design guidelines.

Upon the completion of the project, we believe:Small is beautiful.

但仍有一个问题悬而未决：城市性到底是什么？

Yet one question remains unanswered: What is urbanity?
