中国城市在经历了近四十年的快速发展后，已经到达了临界点，即大规模的空间增长不可持续，土地开发空间严重受限。面对困局，政府与企业都在积极探索城市发展建设的创新之路，思考如何通过更新与再生对现有土地进行功能转型、结构重建，从而与城市创新和新经济相融合。
2019年7月，历史悠久，风格古朴的南京师范大学紫金校区正式结束了教书育人的使命，送走了最后一批学子。南师大紫金校区总共占地面积约11万平方米，地上建筑面积约8万平方米，这里留下了许多人的青葱校园记忆，也留下了这座大学校园与城市的文化链接。
校区位于“紫金山下，玄武湖边”，观山望湖，具有良好的景观和校园独有的生态环境。“板仓街78号”，在这里人文与校园情怀交叠，也构成了知性，包容，创新的学院派氛围。这片校区的未来将何去何从？是仅保留地块，做大范围的革新，或是选择保留校园文化记忆，探寻新的建筑新生？

The Zijin Campus of Nanjing Normal University, where the library renovation project has been complered
After nearly 40 years of rapid development, Chinese cities have reached the critical point of large-scale spatial growth is unsustainable and land development space is severely limited. Both the government and enterprises are actively exploring an innovative way of urban development and construction, thinking about how to transform the existing land’s function and rebuild that structure through renewal and regeneration, so as to integrate with urban innovation and a new economy.
In July 2019, the Zijin Campus of Nanjing Normal University, with a long history and a simple style ended its mission as a university campus. The campus covers a total area of 110,000 square meters, and the “above-ground” building area is 80,000 square meters. It leaves many campus memories for its past students and the cultural link between this university and the city.
The campus is located under the “Purple Mountain, beside Xuanwu Lake”, with views of the mountains and the lake. A good landscape and a unique ecological environment inside it. “No. 78 Bancang Street”, where human culture and campus memories feelings are overlapped, it constitutes an intellectual, tolerant, and innovative academic atmosphere. Which future this campus is heading to? Is it to keep only the land and make a large-scale innovation, or choose to preserve the campus cultural memory and explore an architecture renovation?

向史而新-新型城市文化空间改造与创新
Heritage and Innovation: New Urban Cultural Space Transformation and Innovation
DUTS杜兹设计在2019年接受金地商置的邀请，进行原南京师范大学紫金校区的整体改造设计工作。日前，原南京师范大学紫金校区改造项目的首开区，原“图书馆”的改造已经完成。设计师从建筑历史与城市情感记忆中吸取灵感，将当代设计美学与复合的现代生活业态注入到这座拥有近70年历史的图书馆中，使其焕发新生，成为包容展示、商业、办公、商务、交流等复合功能，与充满人文生活气息的新型地标性文化中心。
如何保留“图书馆”这座公共文化建筑的情感记忆，并使其在当代生活中继续充满生命力，成为了设计师考虑的主要问题。在对空间的反复研究与推敲之后，杜兹设计的设计师提炼了原建筑中的经典元素和记忆点，保留了建筑整体形态与轮廓，并通过现代建筑手法，使其呈现愈加开放与现代的姿态。
DUTS Design accepted the invitation of Gemdale in 2019 to carry out the overall renovation design work of the original Nanjing Normal University Zijin Campus. Recently, the renovation of the original “library” has been completed. The designer took inspiration from the architectural history and the emotional memory of the urban life, and injects contemporary design aesthetics and complex modern life formats into this nearly 70-year-old library. The rejuvenated library becomes a new landmark cultural center that contains complex functions such as display, business, office, business, and communication, and is full of humanistic life.
The retention of the emotional memory of the “library” as a public cultural building and make it continue to be full of vitality in contemporary life has become the main issue considered by the designer. After repeated research and scrutiny of the space, architects of DUTS design refined the classic memory points in the original building, retained its overall form and facade outline, and made it more open and modern through modern architectural methods.

“我们希望这个改造是一种”向史而新”，保留这块土地的人文与情感记忆，通过现代建筑的语言让它更和谐的与当代生活相融。我们做了两步：
第一步，“开”，打开空间，让建筑形态更加开放，打通内与外的交流；
第二步，“合”，注入复合业态，融合现代生活，使它变为一个充满情感，记忆，又有新鲜活力的生活空间。”
—— DUTS杜兹设计创始人，总建筑师钟凌
“This transformation is “Heritage and Innovation”, we retain the human and emotional memory of this site, while make it more harmoniously integrated with contemporary life through modern architectural language.
We did two steps:
The first step is to “open”, open up the space, make the architectural form more open, and open up the communication between inside and outside;
The second step is to “combine”, inject a complex format, integrate modern life, and turn it into a living space full of emotions, memories, and fresh vitality. ”
— Zhong Ling, founder of DUTS Design and chief architect

开：“图书馆”的开放与新生
Opening: Opening and Rebirth of the “Library”
1. 设计立意：开放的“橱窗”
Design Concept: Open “Showcase”
南师大紫金校区的图书馆年代悠久，新的改造在保有原建筑风貌基础上，突破传统的平面布局，打造更具多样性的功能核心，集交通、阳光天井、共享空间于一体。立面交通核体量明确有力，横向则通透舒展。
The library on the Zijin campus of Nanjing Normal University has a long history. The new renovation retains the original architectural style, innovatively breaks through the traditional layout, creates a more functional core, and integrates vertical transportation, sunny patios, and shared spaces. The traffic core of the facade is clear and powerful, and the horizontal is transparent and stretched.

原有的图书馆功能单一，保护书籍，保持安静的读书环境使建筑空间相对封闭。设计师将原有的交通空间打造成一个高24米的公共橱窗，突出其文化的地标性。愈加开放与共享，也正体现了现代城市公共文化空间的发展方向。
The original library has a single function. Protect books and maintain a quiet reading environment to make the building space relatively closed. The designer transformed the original traffic space into a 24m high public showcase, highlighting its cultural landmark. Increasing openness and sharing also reflect the development direction of modern urban public cultural space.

引入“观山平台”，加强内与外的互动关系，空间内的人们，可以在交流的闲暇通过橱窗，遥望紫金山，汲取自然之力，找回内心的宁静。
The designer introduced “mountain viewing platforms” to the building to strengthen the interactive relationship between inside and outside. People in the space can look at the Purple Mountain through the window in the leisure time of communication, absorb the power of nature, and find their inner peace.

2. 平面与立面的“开放”
“Opening” of floor plan and elevation
建筑师将平面打开，重构原有的交通核，电梯、卫生间、共享空间等巧妙植入，并在核心区打造贯通的天井空间，利用垂直的天井引入自然光线，加深自然与建筑，时间与空间之间的互动。
Architects opened up the plan, reconstructed the original traffic core, ingeniously implanted elevators, toilets, shared spaces, etc., and created a perforated patio space in the core area, using vertical patios to introduce natural light, deepening nature and architecture, time and interaction between spaces.

立面造型上保持原本的构图关系，但将原来封闭的竖向体块改为通透玻璃，多个公共平台穿插于其中，在此，人们的活动有了展示的舞台，恰似城市窗，而同时又可以凭栏而眺远处的紫金山美景。历史、功能、景观资源在现代的设计手法下形成了完美的融合。
In terms of façade modeling, the original composition relationship is maintained, but the originally closed vertical volume is changed to transparent glass, with multiple public platforms. Here, people’s activities have a stage for display, just like a window to the city, while at the same time they can lean on a railing and overlook the beauty of the purple mountain in the distance. History, function, and landscape resources have formed a perfect fusion under modern design techniques.

“打开”的书屋
The “opened” bookstore
为延续书籍在这片空间中留下的温暖记忆，设计师将“图书馆”的一层与二层创造成了一个开阔、通透、充满人文气息的挑高中庭空间，空间两侧以连续的完整的书墙来界定，书架分隔的线条延续到天花板形成连续的拱形，强化了空间的精神性，端部则通过自然光线的引入，成为空间中自然与人文的一种隐含沟通。
In order to continue the warm memory of the books in this space, the designer merged the first and second floors of the “library” into an open, transparent and humanistic high-rise atrium space, with continuous integrity on both sides of the space To define the book wall, the dividing lines of the bookshelves continue to the ceiling to form a continuous arch, which strengthens the spirituality of the space. At the end, the introduction of natural light becomes an implicit communication between nature and humanity in the space.

合：注入复合业态，融合现代生活
Combination: Inject a complex business format and integrate with modern life
多元丰富的生活方式为空间带来新的活力。保留原本图书馆的人文气息，设计师为其注入现代城市生活的复合业态，创新性的将开放咖啡厅、共享办公室、餐饮美食、互联网、生态科技等以当代手法注入“图书馆”，成为城市年轻人的社区生活圈。

“What we want to create is a kind of “Growth-able” culture space, which carries the memories of the campus and is also recording the growth of young people in this contemporary city. What remains unchanged is the humanistic feeling in our hearts, preserved in the space.”
