屺园
——园艺小镇文创中心

建筑设计：李兴钢，谭泽阳，姜汶林/中国建筑设计研究院有限公司

2019 北京世园会园艺小镇用地西南，构建了一处既“开放”又“封闭”的公共空间。

场地东北依托传统风貌的特色小镇和花田，南侧与现代化的植物馆遥望。建筑化整为零，由4 个单坡屋顶两两组合形成的L 形体量围合而成。一条内巷将两个体量区隔开来，半高的基座又将彼此连缀。内巷在西北、东南对角方向设置公共漫游出入口，成为园区公共游览系统的一部分，游客经由内巷上达平台，攀至屋顶，赏望远景。使用空间在西南、东北和东南角分设出入口，互不相扰：西南体量为以展厅、讲堂和图书吧为主的文创服务空间；东北体量以制作工坊、纪念品商店等特色产业体验1空间为主；基座下设置管理办公用房和艺术家工作室，与服务区和产业区便捷相连。各组团可分可合，会时各安其位，统一管理；会后亦可合而为一，共同运营。

开放性之余，建筑又希望能实现某种内在叙事，从而跟周边环境中那些非自然的布景式建筑或景观保持适当距离。将建筑进行两分，“筑房拟山”，完成一种特定的景观体验——单坡屋面赋予建筑以强烈的方向性和识别性，同时也完成了象征自然物的“山”与象征人工物的“房”之间的连接和互成：“房”以“山”为对景，位于东北侧；“山”与“房”的基座相连，位于西南侧。相似的坡顶形式，在室内分化成两类不同特征的空间：西南侧体量趴伏，空间呈现出洞穴般的模糊性；东北侧间架清晰，暗合了传统建筑的空间特征；半高的平台将“山”与“房”既隔且连，使西南坡顶成为东北侧“房”内特殊的

“山”的部分采用全现浇清水混凝土墙体承托斜屋面，强化“山穴”的空间特征；“房”的部分采用钢筋混凝土框架与木屋架复合的结构体系，象征传统的木作屋架。“房”中的木屋架采用正交木桁架，等截面的木杆件通过预制的多向钢构件连接，形成既现代高效，又与传统榫卯木作有所关联的复合式节点。

Horticulture Village of Beijing Horticultural Exhibition 2019, which sits in the southwest of the site, produces a both "open" and "closed" space.

The northeast area of the site relies on the small towns with traditional characteristic features while the south side echoes the modern Botanical Pavilion from afar. The building is divided from a whole body into parts, surrounded by the L-shaped volumes formed by two pairs of four single-pitched roofs. The two volumes are separated by an inner alley and connected by a half-height pedestal. The public roaming entrance and exit are set to the inner alley which is located from northwest to southeast diagonally, becoming a part of the public tour system of the park. Visitors reach the platform through the inner alley, climb to the roof, and enjoy the vistas. Entrances and exits are placed independently without interference in the southwest, northeast and southeast corner of the usable spaces, with the southwest volume as a cultural and creative service space dominated by an exhibition hall, a lecture hall and a book bar, and the northeast as an characteristic industrial experience space featured by a manufacture workshop and a souvenir shop.Below the pedestal, there are management office rooms and an artist's studio, which conveniently connect to the service area and industrial area. Each group can be independent or combined, fitting its position under unified management during the exhibition and merges into an entirety operated together after.

In addition to openness, there is a kind of internal narrative which is hoped to be achieve in the architecture, so as to keep a proper distance from the unnatural scenery-style buildings or landscapes in the surrounding environment. The building is divided into two parts, which mean "resemble mountains through building houses", to complete a specific landscape experience, an intense directionality and identification endowed to the building due to singlepitched roofs, and also to accomplish the connection and mutual integration between the "mountain"symbolising natural objects and the "house"symbolising artefacts. The "house" as the opposite scenery of the "mountain", is located in the northeast while the "mountain" that connects to the base of the "house" is set in the southwest. Similar sloping roof forms are divided into two types of spaces with diへerent characteristics. The volume in the southwest is prone which present cave-like indistinct spaces,and the clear frames in the northeast implies the spatial characteristics of the traditional architecture.Half height platform separates and connects the"mountain" and the "house", making the southwest sloping roof become the special artificial "mountain"scenery in the "house" on the northeast side, which is called embodying "mountain" by "house". "mountain","house", eave galleries, attics, pavilions, together constitute a three-dimensional system of tour and view, hence named "Mountain Garden".

Entire cast-in-situ concrete walls support the inclined roof in the part of "mountain", which strengthens the spatial characteristics of a "cave".Composite structural system of reinforced concrete frame and timber roof truss is adopted in the part of "house", which resembles traditional wooden roof frame. The orthogonal timber trusses applied in the"house", in which wood members with uniform cross sections connect each other by prefabricated multidirectional steel members, form composite joints fashionably efficiently, and also connect traditional tenon-and-mortise works.
