水-代表著杭州,也代表著蘊育萬物的來源,就如同兩河交會處所形成的東湖區周圍茂盛的植被景觀,以及周圍所圍繞的大小範圍區域的新舊建築群,逐漸創造出合適的居住區。身為中國六朝古都並具有2,000多年歷史的杭州,正朝向現代化之路發展、創立本身當代化文化、保存其著名花都景觀以及成為?林匹克博覽會之後的現代化區域。如果說西湖是當地歷史文化的代表,那麼雙子塔可說是杭州未來發展的象徵。雙子塔兩棟建築物的設計採用了中國「萬物平衡」的概念來讓各個不同元素間產生正向的連結,也可說是一種「虛實」意象的呈現,在視覺上產生了平衡之感,同時也符合了事務所想創造的意象-一種彼此間的互動與協調,並反映出杭州的現代化及未來的發展性。

雙子塔船般造型的基座如同浮在東湖之上,所有出入口、商店、會議中心、休閒設施及停車場皆規劃在如船型般的基座中,並籍著流線型的橋樑連接至東湖水岸區以及其他周圍的設施。雙子塔由辦公塔及旅館塔所組成,辦公塔外型如同由不同的金字塔疊加組成,而旅館塔從底向上變化的橢圓流線造型更可從辦公塔中反射看見,介於兩棟之間的空間乍看下令人以為存在著第三棟的建築物,這也是事務所刻意想創造出的虛實景色。

雙子塔基座的設計非常具有獨特性,車道從地表往下進入至湖面下三層樓深,約可停放2,200台車的地底停車場。環繞雙子塔四周的湖像似個高起地表3公尺的人工反射鏡,湖的邊緣處特地設計了斜坡式的水牆,讓湖及水牆雖為一體設計卻各有著不同的高度。除了商店、會議中心及休閒設施等等外,基座處也包含了兩棟大樓的機電設施中心及引導逃生至戶外的空間。地下一樓處也設計了通往河流碼頭的通道,一樓處則是零售區及能看到河景及?林匹克博覽會設施的二間會議室;而位於基座上方的空間為車道及開放式的空間,可一覽四周的水景規劃,且在頂樓尚規劃了能觀賞360度市景的空中吧檯及餐廳。在安全的考量下,雙子塔的特地設計了環繞式、網狀由中空鋼材組成的上層結構(superstructure),配合著外部主要的柱體結構以抵抗強風及次要地震的侵襲。

An Urban Garden
Our proposal for the new Twin Towers seeks to transform the Olympic Expo site into a new “Eastlake” district in Hangzhou inspired by the powerful relationships of architecture, water and landscape of world-renown Westlake, but reconsidered as a new kind of Urban Garden of the 21st Century. This new Garden contains variable architectural, landscape and functional elements in composed and dynamic relationships to each other, reflecting the vibrant nature of the future of Hangzhou. As the main symbolic and physical icons of this Garden, two 300 meter uniquely shaped towers balance next to each other in a sculpted ensemble, creating an unmistakable new skyline. The Two Pillars of Eastlake are subtly shaped in response to the each other’s complementary but distinct forms creating a new and memorable image for the future of Hangzhou representing the values of dynamic interaction and cooperation.

EastLake
Water – the source of Hangzhou’s identity - is the source of orientation and serves to establish the identity for “Eastlake” as well as act as the main organizing feature for the mixed use medium and large scale buildings surrounding it. The confluence of the waterways of the Qi Jia River and Li Min River crossing on the site are expanded into a new central “lake” creating a pedestrian level experience focused on moving next to, around and over water in a lush landscape with distinct but changing perspectives to landmark building objects.
Verdant gardens and landscaping surround the lakeshore and line pathways used by pedestrians and automobiles connecting the various points of interest, plazas and entrances to buildings.
The new “Eastlake”, highlighted by the Two Pillars towers, is the symbolic main space of the district and becomes a distinct new urban venue in Hangzhou combining water, urban and leisure activities and a new representative architecture.
Setting
Hangzhou, one of the Seven Ancient Capitals of China, once the seat of the influential Southern Song Dynasty, and now the capital of Zhejian province of modern China, has been a powerful and prosperous city of transformation for over two thousand years. Once referred to by Marco Polo as “Paradise on Earth”, modern Hangzhou is world renown as one of the finest and noblest garden cities in all of the world, exemplified by Westlake and the iconographic gardens, historical bridges and pagodas surrounding it dating back to the dynastic eras that are the landmarks of the city.

Now contemporary Hangzhou is transforming again, and will establish a new representative center of its contemporary culture, importance and modern ambitions on the east of the Qiantang river in the form of the Olympic Expo area. As a symbol of modern Hangzhou, a pair of highrise landmark towers will occupy a central location in this area and form a new representative image of the future of the city along the “Golden Corridor” from the Civic Center directly across the river to the West. Reflecting a relationship to the Civic Center urban area, the new Twin Towers are the central feature of the “Seven Stars arching the Moon” urban development concept of the Olympic Expo area, wherein seven significant towers – peaked by the 300 meter tall Twin Towers - surround the large scale Stadia and Expo facilities of the new district and form a mirror to the Civic Center area.
The new district will take it’s place in the two thousand year history of Hangzhou and the new Twin Towers will be the future icons of contemporary Hangzhou just as the Pagodas of Xi Hu (Westlake) are the icons of the historical Dynastic eras.
Towers – Balance and Dynamic Interaction
The Two Pillars towers are two sculpturally unique objects that work in tandem to form a single powerful image of the future Hangzhou. Inspired by the Pagodas and towers of Westlake, but reflective of the contemporary, dynamic era of Hangzhou, the paired objects use the concept of Composed Balance found in the perspectives of the Chinese Garden to create a positive tension between different elements. This unifying force created by a sculptural and dynamic relationship of solid and void and between the soft and hard shapes, creates visual balance in a manner more complex and nuanced than simple symmetry of two identical objects. The balanced poise of the two related bodies creates a situation of dynamic interaction and cooperation - a condition more reflective of the modern and dynamic future of Hangzhou.

Boat-shaped Base
Functionally and formally the Two Pillars are placed on top of a boat-like podium floating in the center of Eastlake. Like the “Pagoda Boats” of Westlake, this “Boat” carries the new Twin Towers and serves as their functional podium. All access ways and support functions, such as shopping, conference, ballrooms and parking are located in the “Boat”. Fluid bridges and pathways connect it to the shores of Eastlake and the multifunctional uses of the district.

Towers – Function and Identity
Reflecting their different respective functions of Office and Hotel, and like “Brother and Sister”, the two towers each have a different geometric principal but share a common architectural language. They are different corresponding to their function, but work together so that the overall effect is more than the sum of the parts.
The Office tower is a faceted form of three truncated pyramids alternating on top of each other, while the Hotel tower is a fluid, ellipse-based cylindrical tower whose profile changes in an elegant flow from top to bottom. The soft form and 3-dimensionality of the Hotel tower is reflected in the inner atrium void of the Office tower, and the negative space between the two towers is seen as a virtual “third tower” connecting the two objects into one. The sculpted void space of the “third tower” between the two pillars plays as important a role in the composition as the solid objects do themselves.

General
The general program consists of an office tower and a hotel tower resting on a commercial and conference base that contains a central atrium with views to the river and Olympic facilities. The lower parts of the “Boat” plinth contain the parking, delivery and mechanical facilities.

Boat-shaped Base and Access
Entering the project at level 0, vehicular traffic descends under the lake surrounding the “Boat”. This “lake” is an artificial reflecting pool 3 meters above the level of the natural lake formed by expansion of the confluence of the Qi Jia River and Li Min Rivers. The banks of the reflecting pool are sloped ‘water-walls’ so that the pool and the lake are read as one body of water on two different levels.

Vehicular parking is provided on levels minus three and minus four for approximately 2200 cars. There is vertical access here to the shopping, conference, office and hotel levels. Deliveries and loading vehicles descend to level minus two where a combined delivery area for all four components of the building is located. This level also contains the main mechanical space for the towers and commercial conference facilities.
The minus one level is a retail level that also provides connections to the surrounding underground development while also providing escape routes to the street beneath the reflecting pool at level 0.
The minus one level also provides a connection with the river at a boat dock that is connected to the main atrium of the boat plinth.
Level zero in the plinth is divided by the central atrium in the north-south direction, while functionally divided in the east-west direction into retail and conference center facilities. Two 1200 square meter large ballrooms or conference rooms face the view of the Olympic complex and the river. These can be divisible into many smaller conference rooms.
The level plus one is also divided by the central atrium and split into conference and retail areas where both the office tower and hotel tower have access to the shopping and conference centers. The top of the boat plinth not only provides drop off and taxi zones for the office tower hotel tower and shopping, but also provides an open terraced plaza with a water feature that cascades from two sides of the plinth to the water landscape below.

Office Tower
The 70 floor and 300 meter tall office tower contains a 20 meter tall, impressive entrance lobby with a separate porte cochere drop off on the top of the “Boat”. Vertical access to the floors is via double cab shuttle elevators to two different sky lobbys where double passenger elevators will service the floors in between. Each office floor is open to a sculpted atrium along the West that extends through the entire building creating space for hanging gardens and common spaces for interchange of ideas. The Atrium adds open, green common space to each office floor and makes the arrival experience unique at each level..
The offices can be utilized as single or multiple user floors and can be separated into up to five different tenants per floor. These offices provide natural day-lighting and individual solar control. The upper two floors of the tower are reserved for executive offices and each contain a mezzanine floor and have double height spaces. The common spaces of the office tower are located at the top of the building reserving the best views for the restaurant and sky bar, both of which are double height with interstitial floors.

The Hotel Tower
The Hotel entry from the porte cochere drop-off on top of the “Boat” includes a soaring 25 meter lobby with access to the 60 floor and 300 meter tall hotel tower above and shopping, ballroom and conference facilities below. The five star luxury hotel tower contains 550 rooms and suites with an option for an additional 235 rooms or 90 Serviced Apartments, all with impressive views to the Eastlake gardens, the Quintang river and Hangzhou skyline beyond.
Two banks of passenger elevators service the low rise and high rise portions of the tower, while four service elevators are also included in the central core.
The hotel is organized with administrative and back of house functions in the lower floors above the lobby, 23 levels of rooms and suites in the middle portion, executive and club floors from levels 35 to 39, then optional additional hotel room floors or serviced apartments from level 40 to 52. The Hotel Tower is topped by the amenity floors containing wellness, sky bars and restaurants all with expansive 360 degree views of Hangzhou. Sky lobbies occur between the standard and executive floors containing space for club lounges and vip rooms.
