Appreciation towards Asif Khan for providing the following description:

英国著名的建筑事务所Asif Khan设计了2020迪拜世博会的入口，这三座通往世博会的壮观入口将于2021年10月20向游客开放。该事务所在2020世博会超过六公里的公共区域进行了设计，这些装置是首次公开的作品。它们是对传统的阿拉伯窗花“mashrabiya”的现代探索，“mashrabiya”是一种优雅的设计元素，用于控制当地的光线和通风。每个入口的外观十分宏伟，均由超轻碳纤维复合材料编织而成，这种复合材料具有极高的结构强度。这使入口高达21米，长达30米，并且不需要任何额外的支撑。从远处看，入口似乎是半透明的平面，近距离观察便可发现它是由数百条结构线条组成的。

Asif Khan, renowned British architecture studio, has designed the Expo Entry Portals, three spectacular gateways to Expo 2020 Dubai that will grant entry to visitors from 20 October. The structures are the first works to be unveiled from the studio’s design of more than six kilometres of Expo 2020 Public Realm. The portals are a futuristic exploration of the traditional “mashrabiya”, an elegant design element used across the region to control light and airflow. Each portal’s remarkable appearance comes from being woven entirely from strands of ultra- lightweight carbon fibre composite that lend incredible structural strength. This enables the ethereal portal structures to stand 21 metres high and 30 metres long, without any additional support. From afar the portals appear to be composed of translucent planes, which up close visitors discover are made from hundreds of fine lines of structure.

入口装置设有两扇巨大的门，每扇高21米、宽10.5米，世博会为期173天，每天早晨它们都会打开，象征对世界的欢迎。大门引导游客至种满树木的庭院，该庭院也由Asif Khan设计，分别位于世博会的机遇（Opportunity）、流动性（Mobility）和可持续（Sustainability）三个展区。设计师携手一家专注于大尺寸碳复合材料组件的制造商和一名飞机工程师，在历时三年的反复设计中完成了该项目。最终的几何形体解决了结构强度对材料效率、透气性、遮光量以及制造时间的要求。该项目受当地美学的启发，壮大了过去世博会中丰富的创新型结构系列。

The portals feature two vast doors – each door is 21 metres high and 10.5 metres wide – which will be opened every morning of the 173 days of Expo 2020 Dubai in a symbolic act of welcoming the world. They lead visitors to tree-filled arrival courtyards, also designed by Khan, in each of the three Expo 2020 districts: Opportunity, Mobility and Sustainability. The project is the outcome of a three-year iterative design process working hand in hand with a manufacturer specialising in large format carbon composite components and an aircraft engineer. The final geometric pattern resolves the requirements of structural strength against material efficiency, wind permeability, shading quantity and manufacturing time. Adding to the rich lineage of innovative structures from past World Expos, these portals are a future form of architecture which is inspired by the aesthetic of the region.

Asif Khan还对宽敞的公共区域进行了设计，六公里长的线性公园贯穿了三个入口，旁边设有跑道、软硬材质的步行道和休息场所。水景、植物和树木改善了整体环境，其中一个座椅项目是与黎巴嫩印刷师Lara Captan合作设计的。地面上的线条代表人们穿越沙漠时留下的痕迹，它们沿着装置移动、融合，形成的图案仿佛阿联酋的传统编织物。设计使人们能够以自己的步伐探索世博会的浩瀚。世博会结束后，它将成为新区的永久街景。

Khan’s wider Public Realm design interweaves a six-kilometre linear park with the entire length of concourse, alongside a running track, walking paths of soft and hard materials and places to rest. Among these are a seating project, designed in collaboration with Lebanese typographer Lara Captan, water features, plants and trees which complete the environment. Representing the lines left on the desert as people journeyed across the landscape, the multitude of lines in the ground follow the concourses, flowing and converging with each other using a language of pattern work inspired by the UAE’s traditional sadu weaving. The design enables people to explore the Expo’s vastness at their own pace. After Expo, it will become a permanent streetscape for the new District 2020.

Asif Khan说：“对于所有前往2020迪拜世博会的人来说，这些入口将见证他们与世博会第一次也是最后一次相遇的时刻。同时，它们也捕捉了该地区首次举办世博会的超凡瞬间，这场庆典不仅关乎阿联酋的传统，也关乎未来。为2020迪拜世博会设计公共区域对我来说是一个开创性的时刻，从入口到我与Lara Captan合作设计的座椅，设计的每一处都使游客沉浸在伊斯兰文化、艺术以及与世博的未来精神的对话之中，我希望这能给他们留下难忘的印象与体验。”

Asif Khan said “The portals will be the first and last encountering moment for all who make the journey to Expo 2020 Dubai, and these capture the very transcendental moment the region is experiencing as it hosts its first World Expo – the celebration not only of UAE’s heritage, but also the future. Designing the Public Realm for Expo 2020 Dubai is a seminal moment for my practice; each aspect of the design invites visitors to immerse themselves in shared Islamic culture, art and language in dialogue with the future spirit of Expo. As visitors explore the many facets of the Public Realm designs, from the Expo Entry Portals to the seating I made with Lara Captan, I hope it leaves them with an unforgettable sense and experience of place”.

2020迪拜世博会首席发展官和交付官Ahmed Al Khatib说：“我们迫不及待地想在2020年10月20日向世界敞开大门，世博入户大门将以绝妙的方式欢迎世界各地的数百万游客，使他们在园中体验惊奇的建筑和突破性的创新。”对于参加该地区首届世博会和阿拉伯有史以来最大规模活动的数百万游客来说，世博入口将是他们到达园区的第一印象。由于疫情原因，2020迪拜世博会将于2021年10月1日至2022年3月31日期间开放。

Ahmed Al Khatib, Chief Development and Delivery Officer, Expo 2020 Dubai said: “We cannot wait to open our doors to the world on 20 October 2020, and the Expo Entry Portals will provide a wonderful way to welcome millions of people from across the globe, giving a taste of the amazing architecture and groundbreaking innovation they will experience all around the site.” The Expo Entry Portals will be the first impression of the site upon arrival for the millions of visitors who will attend the first World Expo and largest event ever to be held in the Arab world. Expo 2020 Dubai will be open from 1st October 2021 – 31st March 2022.
