“微縮北京”——大院胡同28號院改造項目，位于北京舊城區域，由原來占地面積262平米的普通雜院，改造為五套帶院落居住公寓+一套咖啡/餐茶公共空間。由喧鬧的城市商業街區轉折進入閑適寧靜的胡同區域，再由外部胡同通過一條半室外主巷道和一條再次分支的巷廊，分別進入北側、南側不同格局和規模的五套“合院”公寓，幾條線型混凝土結構/空間單元構成了內含于整體院落群組建筑的空間架構。每套公寓擁有大小、形狀變化的院庭，主要起居空間通透，面向并對景于庭園；由主巷道繼續南行，經咖啡/餐茶空間，抵達后面的小公共庭園，并可沿一側的混凝土階梯，上至抬升在庭院上方的亭樓平臺。夕陽西下之時，游者在此可觀想、沉浸于由舊城層疊屋頂、古樹、飛翔的鴿群、遠方城市高樓群所構成的深遠勝景。

這個微小項目是一次結合了舊城更新、院落改造、理想居所研究的設計實踐: 以研究傳統北京的復合性城市結構為基礎，認識并運用其結構可延伸、加密的特征，通過分形加密，將大雜院轉變為“小合院群”；“宅園”與“公共單元”的設置適應了現代社會結構，將院落轉變成“微縮社區”；居所層面極限尺度的技術性設計服務于“宅園合一”的精神性營造，通過空間敘事，將日常詩意與都市勝景的體驗帶入“理想居所”；以個案回應了北京舊城更新的“三道難題”，并探討向更廣泛的社區、城市擴展，恢復北京舊城“自生機會”的可能性。

The conversion of No. 28 Dayuan Hu Tong, titled ‘Miniature Beijing’, which is an Atelier Li Xinggang’s recent project completed in 2017, is located in the old city area of Beijing. A common courtyard house of 262sqm is transformed intofive apartments with self-contained courtyards, as well as a public space that host café and tea house. Turning from the noisy urban commercial streets into the peaceful and leisurely Hu Tong district,then through the outside main Hu Tong to a semi-external ally way and a further smaller lane, separate paths lead to the north and south courtyard apartments of different size and configurations. Several linear concrete structural / spacial units form the elemental spacial formation within the entire courtyard complex. Each contains a courtyard that is varied in size and shape. The main living room of each apartment is spacious and bright, benefits from the view of the garden. Travelling further south along the main ally way, passing the café and tea house, visitors reach the small public garden at the rear and arrive at the platform of the pavilion elevated above the courtyard via a set of concrete steps on the side. With the setting sun as the backdrop,the profound scenery composed of stacked roofs in the old city, ancient trees,fiying pigeons and the new city high-rises in the distance bring visitors into much contemplation.

This small experimental project is a design practice that combined old urban renewal, courtyard renovation and ideal home. Based on the study of traditional Beijing’s complex urban structure, and with the understanding and utilizing of its extended and densified structure, the crowded courtyard house was transformed to collective small courtyard dwellings by the method of fractal densification. The layout of“house-garden” and “public unit”fit in the structure of contemporary society, turning the courtyard house into a “miniature community”. The technical design of minimum sized dwelling serves the spiritual build of“house-garden harmonization”, and bringing the experience of daily poetic and urban scenery into “ideal living environment” by space narration. The individual case responds to the “three problems” of Beijing’s old urban renewal, and investigates the possibility of it extending into wider ranges of communities and urban space, and recovering the “self-generating opportunity” of Beijing’s old urban.
