香港中文大學建筑學院成立于1991年，是香港第二所可提供建筑專業教學的院校。建筑學院最初為社會科學院下屬的建筑學系，在校學生約為250人，開設五年制本科及碩士學位課程。此外，建筑學系未設其他專業，其教學樓與教工部共用。2010年，建筑學系正式更名為建筑學院，計劃增設城市研究本科課程及城市設計、節能和可持續設計等碩士課程。隨著本科招生人數的增加，學院也將需要更多的空間。

因應政府政策及發展需要，學院將過去的三年制改為四年制。鑒于政府提供了基礎設施擴建資金，大學方面決定新建一部分設施，以迎合學院需要。經過詳細校園規劃，校方決定將校園內的一小片地塊劃歸學院，新建獨立專用的建筑學院大樓。這在香港對于像我們這樣僅有450～500名學生的院校來說是非常罕見的。

建筑學院針對該項目提出了兩點要求，而這也獲得了大學方面的慨然同意。第一點是通過限制性競賽獲得新建大樓的建筑設計方案。第二點是將建筑圖書館搬遷至新的建筑大樓，這與大學方面要求將全部圖書館整合到一個中央圖書館的想法是相違背的。但我們認為圖書館是一所建筑學院的焦點所在，因此不能與學院的教學空間相分離。

此次限制競賽分兩個階段進行，邀請了多家國際性小型創意公司參與，共收到約80份提案。國際評審團最終決出了6名入圍者，之后通過詳細方案評估，確定雅砌建筑設計有限公司在此次競賽中勝出。這家

The School of Architecture of the Chinese University of Hong Kong was founded in 1991, the second school offering professional education in architecture in Hong Kong. The School started as a department of architecture within the Faculty of Social Science, having a total of around 250 students for five years of undergraduate and master degree education. There was no other discipline being offered. The department was housed in a generic academic building together with some departments of the faculty. In 2010, the department was officially renamed as School of Architecture, with plans to offer bachelor programme in urban studies and master degree programmes in sustainable design,urban design, conservation design and others. The intake for undergraduate programme has also been increased. This necessitated the increase in the physical space of the School.

This development coincided with the government's initiative to have a four-year undergraduate study period, rather than three years in the past. Government funding was provided for infrastructure enlargement and thus the university decided to have part of the new facilities catering to the need for the School. With a detailed campus planning process, the university identified a small piece of land on campus that might be used to build the School building, and School was happy that the university had determined that it should have a new and stand-alone building. This is rather unusual in Hong Kong for a small school like ours with only 450～500 students.

There were two requests from the School for this project and the University graciously agreed.One was that the architectural design for the new building had to be procured through a limited competition. The other was for the architectural library to be relocated to the new building, which is very much against the trend in amalgamating all libraries within the university under one central library. We regarded the library as a focal point for an architectural school and thus requested that it should not be separated from the teaching spaces of the School.

建筑大樓規劃用地緊鄰園區主干道（從港鐵大學站延伸至中央校園），而另一側緊鄰鐵路線。其占地面積為2375m2，地塊緊湊，建筑面積為7720m2。項目為期約3年，于2012年夏竣工。

大樓的設計理念是旨在創建一個建筑知識學習型社區。為此，其建筑物必然是可允許學生穿梭其間的典型空間建筑。作為學習型社區，集聚功能是非常重要的。因此，大樓設計了一個中庭，以便形成可供兩樓層使用的公共空間。下層入口處設有臺階式看臺，可供落座、工作、聊天、演示和展覽。此外，還配備有大型投影屏幕，可供夜間舉辦講座和活動使用。教室和制作實驗室位于入口處。上層是一個沿建筑長度而設的大型空間，可供審圖、評圖、展覽、演講及會議之用，并可進一步被劃分為6個隔音空間或一個完全開放式空間。在舉辦活動期間，整個該區域都將變成一個活力樞紐，從上方的走廊和工作室均可見。

中庭旁有兩棟樓，較小一棟為面向主干道而建的五層小樓，設有教職員工及研究生辦公室和研究實驗室。較大一棟為兩層互通的工作室，面向鐵路軌道線。工作室計劃面向所有學生開放，因此，不同班級和不同專業的學生可相互觀摩，比肩學習。每層還設有兩個玻璃隔間，用作激光切割間、小型車間、文印室和噴漆室等。這樣，學生可直接在工作室制作模型。此外，還有兩個面向大型鳳凰樹林的陽臺，可用作學生的休憩空間。工作室與大廳之間的玻璃隔斷可為中庭提供視覺連接效果。工作室大樓的樓頂為開放式露臺，可俯瞰吐露港，也可作活動和休憩空間。隨后在露臺一側修建社區農埔。

在工作室入口對面，建筑圖書館面向中庭而建。圖書館與工作室大樓相距5步，在面向中庭的長度范圍內設有玻璃圍合的閱讀區。同樣地，圖書館內的學習區與中庭及工作室大樓的樓頂區域之間存在視覺觸點。建筑圖書館內有藏書逾10,000冊，涵蓋建筑、城市設計、景觀設計和藝術歷史等。此外，館內還珍藏有一批珍稀的東西方建筑史書籍。從中庭底層和緊鄰圖書館的工作室大樓向上看，圖書館象征性地位于中心位置，因此，圖書館的位置非常重要。圖書館24小時開放，無人值守，可全天甚至是直至清晨都得到持續良好地使用。

A limited competition was conducted in two phases with small creative firms invited to participate internationally, and around 80 submissions were received. Six fi nalists were selected by an international judging panel which ended with a more detailed proposal from the fi nalists and the design proposal from ARCH Design Architects Ltd.won the competition.The small Hong Kong practice is helmed by Wallace Chang and T.C. Yuet, both teaching at the School. In the development of the plan, the firm worked closely with the School in both functional as well as architectural solutions.

The site allocated for the architecture building is bounded by the main road of the campus leading from the MTR University station to Central campus,and the railway line on the other side. Site area is 2,375m2and within the tight site, the total gross floor area built is 7,720m2. The project period was around 3 years, with the building completed in summer 2012.

The concept of the design is to create a community for architectural learning.The building has to also be an exemplary architecture so as to serve as a model for students passing through the space. As a learning community, gathering is very important, and a central atrium is created to facilitate two levels of communal spaces. At the lower level with the entrance is a space with a stepped grand stand for sitting, working, chatting,presentation and exhibition. The space is also used for evening lectures and events with a large projection screen. Classrooms and fabrication labs are located on the entrance level. On the upper level of the atrium are large spaces for reviews, critics,exhibitions, lectures and conferences, running the length of the building, which can be sub-divided into 6 acoustically-insulated spaces or fully opened as one space. During events, the whole space is turned into a vibrant hub which can be seen from corridors and studio located above.

Beside the atrium are two blocks of accommodation,the smaller one on five floors facing the main road has offices and research labs of the faculty members and graduate students. The larger one houses interconnected studio on two fl oors facing the railway track. The studios are fully opened plan so that students from di ff erent years and di ff erent disciplines can rub shoulder with each other and peek over the desk to see what is being done by classmates. On each floor, there are two glass cubicles to contain laser cutting machines and small workshop, printing room,spray room etc. This will allow the students to have

中庭照明依賴于全景天窗，全景天窗上裝有光伏電池，可為兩間淋浴室提供熱水。通過樓梯，向上可到達中庭，橋梁跨設于高聳的彩繪空間之上。沿其中一座中心橋梁，設有多功能立方體，常用作臨時教學和討論空間。其設計原型也許源自于典型中式庭院中沿蜿蜒道路而建的涼亭。實際上，中庭內蜿蜒的小路也是探索之路，逐步揭示出了學院建筑中蘊含的虛擬空間體驗。顯然，學院鼓勵學生棄電梯而就步行，以節約能源。

清水混凝土的質感以及膠合板和生鐵的運用使其融入了當代建筑語言，而其原始的空間形象也迫使人們將目光轉向其生動的視覺環境。同時，中庭還是一個包容性空間，構建成為一個保護和培育未來建筑師的社區。□direct access from their studio to tools of production for their works. There are two balconies too so that students can have a breathing space facing a large fl ame-of-the forest tree. Glass partition between the studio and the atrium also allows visual connection to the community hub. On the roof of the studio block is an open terrace overlooking ToloHarbour which can be used as event space and relaxing space.A community garden was later created on one side of the roof.

Facing the atrium, opposite the entrance on the studio level, is the Architecture Library.The library is only 5 steps away from the studio and has a glass reading area facing the length of the atrium. Again,those studying in the library would have visual contact with the community hub in the atrium as well as the roof of the studio block.The Architecture Library has a collection of more than 10,000 volumes of architecture, urban design, landscape design and art history books. In addition, there is also a fine collection of rare books in Western and Chinese architecture history. The position of the library is critical, as it is symbolically placed in a central position as one looks up from the atrium floor, and right next to the studio. The library was equipped to function as a 24-hour library without supervision, thus it has been constantly well used and particularly late into the early morning.

The atrium is lit with full skylight fitted with photovoltaic cells for generating heated water for the two showers in the building. A stair climbs up the atrium with bridges crossing over the tall Piranesispace. A cubic box serving multiple functions is placed along one of the central bridges used frequently as an impromptu teaching and discussion space, perhaps the prototype is a pavilion along the meandering path of a classical Chinese garden.Indeed, the path that can be followed in the atrium functions as the path of exploration, a path of stepby-step revelation of the spatial experience of the void embedded in the School building. Obviously,students are encouraged not to take the elevator but walk up the atrium for conserving energy.

The rawness of the fair face concrete, the use of plywood timber and rusted iron fit into the contemporary architectural language in addition to feeding the image of a primal space forcing the attention of the users on the visual and kinetic environment. At the same time, the atrium is an embracing space, protecting and nurturing, and creating a community of would-be architects.
