四座建筑由北至南分別為科技館，青少年宮，公共藝術館，書城。出于使用時間和頻率不同，四座建筑策劃的出發點及定位不盡相同：館一是目前深圳展示面積最大的以科學創新因子為題的科技館，強調科學教育資源的共享，旨在為青少年兒童打造一系列科普公益課程；館二為青少年宮，八千多平米的展示空間包含多個人文知識體驗探索專區。館二中的半開放教室及多功能廳、演播廳亦可以成為少兒文化節目的錄制場地；館三引進了先進的多媒體展示手段、以互動式、探索性觀展模式激發青少年的設計創新思維，承擔著創新藝術交流的職能。館四則為公共性質的圖書中心，承載著閱讀和體驗的雙重目的，也是線下簽售活動的重要基地。

從場地上看，這組建筑最大的設計挑戰，在于從超長（410mx60m）的用地限制中，建立起自身的空間秩序。狹長的基地地塊西鄰商業街區及客家圍屋，東鄰空曠的龍崗廣場。一個街區，兩條馬路，如何在這樣“高密度”建筑群與“零密度”城市廣場中間成為一個強有力的空間邏輯組織仍需要反復琢磨。設計最后通過斜柱、斜墻來消解其長方形的格局；體量上通過開口創造出多條人行動線模糊項目邊界。建筑體量從地表升起，五層樓的高度設置首先緩解了龍城廣場和客家圍屋之間高差所造成的視覺壓迫，倒金字塔式的外形又巧妙的在兩兩場館之間圍合出一個小型廣場。人流可自如穿梭于南北兩側，為建筑群體之間可通達的最短距離創造條件。龍崗三館南鄰深惠路與地鐵三號線，北側與城市主干道龍翔大道相連，復合功能的土地利用不僅明晰了人群到達和進入建筑的方式，也銜接了建筑與城市的公共道路及交通。

從建筑表皮的建構看，幾個建筑單體大小不同的形體外墻均采用的直立鎖邊板材為預輥涂的紫紅色鋁板, 0.9 毫米厚,大約為330 毫米寬，分線位置與內部混凝土的暗梁格柵相互契合，轉角及大斜面處采用鋼筋混凝土與GRC 加直立鎖邊鋁板幕墻，與窗洞口自然過渡。傾斜的橫向長條窗的打破空間的儀式感和穩定性，趣味性的劃分給觀者帶來一種流動的“沖浪”感覺。全過程BIM 設計保障了這座建筑必要的實施精確性。從方案階段開始，國際聯合團隊通過3D 模型全方位觀察區域內的直立鎖邊排布規則及板材尺寸，以便指導施工選材和空間定位。

Urban connector: Located in the eastern Longgang district of Shenzhen, the Cultural Center contributes a rich and varied cultural programme housed in an iconic urban connector.Sitting on a long and narrow 3.8 hm2 site with strict height restrictions, the building connects the surrounding areas by subdividing the programme into separate volumes. The passages between these buildings, which align with the adjacent roads, provide access from the new business district on the west side of the building to the park on the east.

The volumes all have curved edges and tilting facades made from pre-rolled purplish red aluminium plates, which frame dynamic views, shelter public squares and naturally guide pedestrian flows.

The fluid forms also channel air currents and provide protection against the sun and rain in Shenzhen’s subtropical climate. By sharing the same formal language, height and material,the volumes form a visually cohesive whole without an apparent front or back facade.

Varied cultural programme: The Longgang Cultural Center has four main programmatic elements: an art museum, a youth center, a science center and a book mall. The science center focuses on popular science for children and young adults. Next to it, the youth center offers an 8000m2 place for extracurricular activities. The art museum combines public arts on the upper floors with an urban planning center on the ground floor and in the basement. By locating the entrances to the cultural centers at the covered squares,the various cultural programmes can extend outdoors. The largest of the four volumes contains a “book mall”—a mall exclusively for books and book-related events such as book-signing sessions, book launches and exhibitions.

Interior structure: The in-situ concrete structure was carefully designed to become part of the visitors’ experience. The structural facade of each volume integrates beams, columns and massive concrete cores, resulting in a building where everything is revealed. The fullheight tilted interior spaces at the edges of the volumes become architectural highlights where the visitor can experience the impressive scale of the construction elements.
