Architects: LWK + PARTNERS

中共中央国务院于2021年9月公布《横琴粤澳深度合作区建设总体方案》，将横琴岛划为“横琴粤澳深度合作区”，确立粤澳两地协同发展的战略局面，以及横琴在粤港澳大湾区建设中的示范角色。与澳门一水一桥之隔的横琴岛地处珠海南端，是连接珠海与澳门的中枢点，拥有与澳门融合发展的先天优势。随着基础设施逐步完善，两地经济社会发展融合，在横琴居住、就业的澳门居民大幅增加，人员交流将逐渐频繁。

中国珠海横琴口岸综合发展项目位于横琴口岸之侧，建筑师充分利用其交通优势，将公共交通导向型发展（TOD）理念融入项目规划及设计，配合横琴岛目前独特的发展机遇，打造兼具多元化功能、高效便捷的城市门户会客厅，为城市升级创造有利条件。

双城交汇枢纽

中国城市化进程加速，面对人口密集、交通挤塞、环境污染等大都市问题，不但对城市资源造成压力，更直接影响人们的生活质量。TOD作为现时国内重点的城市发展模式，通过有效组织多元化的功能空间，以轨道交通和友善通达的步行网络贯穿项目和周边社区，能更有效地使用土地资源，建立居住、工作、休闲和公共服务互相连接的短距离生活圈，以“站城一体化”的生活模式激发社区活力。

TOD模式尤其适合应用在轨道交通相对发达的高密度城市，但由于每座城市的经济、社会和环境情况都不尽相同，TOD作为大规划社区发展模式也没有一个统一定义，不可直接复制和导入任意城市，而是必须按照城市本身的人口密度、出行习惯、发展目标、文化历史等特性而调整，才能成功为城市赋能增值。

横琴口岸综合发展项目由一栋203.9m超高层塔楼、一栋164m超高层塔楼、4层商业裙楼及4层地库组成，设有办公楼、酒店、零售及商务公寓，直接连系与澳门的通关口岸及商业设施。2020年开通的广珠城际铁路延长线及未来澳门轻轨延线将在横琴口岸对接，而项目距离大型豪华娱乐场所及酒店林立的澳门金光大道，更只需数分钟车程。

城市门户会客厅

在岛上土地资源限制下，横琴口岸综合发展项目采取垂直发展策略，对功能空间、公共空间、绿化景观进行立体划分，建构一个拥有城市会客厅功能的TOD综合体。项目从布局和建筑设计上与横琴口岸综合交通枢纽的通关、交通组织方案以及周边街区连接紧密衔接，并妥善利用地下空间、人行天桥等进行多层动线分流，满足公共疏散联系空间的要求，并提供舒适的使用体验。依托强劲的区域发展势头，项目的枢纽角色更为明显，带动横琴的生活及产业升级转型。

横琴口岸综合发展项目的设计综合考虑周边环境布局及路网结构，与口岸设施直接连系，致力建设舒适便捷的城市慢行系统，降低行车需求，满足“晴天不打伞，雨天不湿鞋”的全天候出行需要，构筑以人为本的步行环境，鼓励健康可持续的现代生活模式。

规划上以裙楼商业作为生活和工作之间的连接空间，引入灵活多变的开放公共空间，保持与室外环境的交互连系，为都市人群提供流畅的场景转换及换乘体验，同时减轻建筑体量，营造门户商业气氛。

设计体现横琴岛城文化特色

项目运用现代设计手法，塑造具有生态建筑特征的建筑，体现横琴“山水都市、生态岛城”的特色，突出以人为本的城市人文精神。高层塔楼的空间形象塑造了高低错落的天际线，以横琴的山脉地貌为灵感，同时避免天际线和竖向线条过于长直，采用流线型设计和海洋色彩融入周边景观，体现海滨生态城市特色。

设计团队重视建筑细部设计，融入了横琴符号、风格、形式和构建做法，展现宜人尺度。立面以简洁明快设计为主，避免大量装饰性构件，每层使用横向构件进一步平衡高耸塔楼的尖锐感。立面尺度、肌理、材质也与相邻建筑保持关联。

为节约能源及实现亲近自然的建成环境，项目的总平面规划、建筑平面设计和构造设计都有利于夏季遮阳与自然通风。另外，团队重视第五立面设计，平屋顶均设计为绿化屋面。建筑方案符合《绿色建筑评价标准》（GB/T50378-2014）三星级标准。

下一个趋势：绿色TOD

随着国内社会大众对自然生态和环境健康日益重视，TOD的规划思路已从纯粹功能多元化、高效紧凑和出行便利，逐步转型为以舒适生活体验、低碳建设、人城自然和谐发展为目标，从“站城一体化”迈向“站城人一体化”。

LWK + PARTNERS总结多年经验所得，视“绿色TOD”为应对快速城市化和城市交通挑战的可持续发展核心动力，紧扣每个城市可持续绿色发展所蕴涵的特性。随着信息科技前进发展，TOD作为商业和人流的集中地，将与智慧城市建设交互影响，实现城市可持续高质量发展。□

In September 2021, the State Council of China officially announced its plan to build a Guangdong-Macau in-depth cooperation zone in Hengqin, an island located in the southern part of Zhuhai in Guangdong's, separated from Macau only by a bridge. While Hengqin has always been a natural connection point between Macau and Guangdong, the plan is a strong statement of a synergistic future and deeper integration for the neighbours. Under the new framework, intensified economic and social cooperation between the two and greater improvements in urban infrastructure can be expected. As more Macau residents will choose to live or work in Hengqin, cross-border mobility and exchange will also shoot up.

Hengqin Port Mixed-Use Development is situated right beside the Hengqin Port itself. Architect LWK + PARTNERS designed it as a transit-oriented development (TOD) with efficient programmes closely integrated with convenient transport, setting an excellent foundation for capturing the latest development opportunities. As a multipurpose development, the project makes an engaging urban lounge at the city's gateway which revitalises the island community.

Super Node of Two Cities

Rapid urbanisation has brought a range of urban threats to cities of China, such as densification, traffic congestion and environmental pollution, just to name a few. These not only put pressure on resources, but are directly affecting the quality of life of the inhabitants. TOD has consequently risen as a major development model in Chinese cities, which forms walkable neighbourhoods through effective planning of functional spaces, railway connections and the creation of a friendly and accessible pedestrian network. The result is "station-city integration" emerging as a way of living that energises the community, providing more efficient use of land and growing interconnectedness between living, work, recreation and public services.

The TOD model is best fit for high-density cities with extensive railway networks. However, as every city is economically, socially and environmentally unique, there is no single way of building successful TOD communities. For cities to gain the most from TOD, its planning and design principles must be adapted with consideration of local characteristics like population density, travel habits, development goals, culture and history.

Hengqin Port Mixed-Use Development consists of two super high-rise towers standing at 203.9 metres and 164 metres with a four-storey podium and a four-storey basement. It has offices, a hotel, retail spaces and serviced apartments directly connected with the port and associated commercial facilities. The Hengqin Port is where the Guangzhou-Zhuhai Intercity Railway extension, opened in 2020, meets the future extension of Macao Light Rapid Transit, while the famous casino- and hotel-studded Cotai Strip in Macau is just a few minutes' drive away.

Urban Gateway, Urban Lounge

Hengqin is an island with limited land. Hengqin Port Mixed-Use Development adopts a vertical programme with a strategic organisation of functional spaces, public spaces and landscaping, creating a strong urban connector. While it links the port's facilities, traffic planning and surrounding streetscape with thoughtful planning and building designs, multilevel underground spaces and footbridges allow people to channel through communal areas and enjoy a comfortable user experience. As regional development speeds up, the project is well positioned to facilitate further reform and upgrade of the city's industries and living standard.

The project brings about a comfortable and convenient slow mobility system that unifies with its surrounding environment, road network and the port. An all-weather walking route is set out to reduce the need for cars, encouraging a healthy and sustainable lifestyle in the community.

The retail podium is planned as a link between lifestyle and work, with a diversity of public spaces to promote the integration of outdoor and indoor spaces and provide an engaging transitional zone for passers-by and interchange passengers. It also relieves the impact of the building mass and creates a sense of arrival for those entering the city through the port.

Building Design with Local Characteristics

Embracing Hengqin's goal to become an ecofriendly city, the project's modern architectural language expresses both a humanistic spirit and respect for urban ecology. The two towers stand in complementing heights with one another to create a dynamic skyline inspired by the natural landscape in Hengqin. By adopting a streamlined design and marine palette, it also avoids disrupting the native landscape and coastal environment.

LWK + PARTNERS consciously incorporates local symbols, styles, forms and construction methods in the architectural details. The façade is clean and simple, free of over-decorative elements and with horizontal features on every floor to balance out the sharp tall tower form. The scale, texture and materials of the façade also resonate with the adjacent buildings.

To save energy and foster a biophilic built environment, the overall planning, layout and building fabric are all designed to favour summer shading and natural ventilation. Green roofs are also treated as a fifth façade to raise the presence of natural greenery. The project qualifies for a threestar rating underChina's Assessment Standard for Green Building(GB/T50378-2014).

Next Trend: Green TOD

As China's society becomes increasingly aware of natural conservation and environmental health, TOD as a planning approach is shifting from a purely functional, efficiency-driven and compact model to one that aspires to liveability, low-carbon building and harmony between people, cities and nature. The idea of "station-city integration" is moving towards "station-city-human integration".

Years of experience has led LWK + PARTNERS to believe that Green TOD is the core driver of sustainable development amid rampant urbanisation and traffic challenges, while also taking into account every city's unique characteristics. The advancement of information technology and smart city initiatives will also be closely linked with TODs, which are urban centres with intensive business and foot traffic, in realising sustainable urban development.□
