2019 北京世園會(huì)園藝小鎮(zhèn)用地西南，構(gòu)建了一處既“開(kāi)放”又“封閉”的公共空間。

場(chǎng)地東北依托傳統(tǒng)風(fēng)貌的特色小鎮(zhèn)和花田，南側(cè)與現(xiàn)代化的植物館遙望。建筑化整為零，由4 個(gè)單坡屋頂兩兩組合形成的L 形體量圍合而成。一條內(nèi)巷將兩個(gè)體量區(qū)隔開(kāi)來(lái)，半高的基座又將彼此連綴。內(nèi)巷在西北、東南對(duì)角方向設(shè)置公共漫游出入口，成為園區(qū)公共游覽系統(tǒng)的一部分，游客經(jīng)由內(nèi)巷上達(dá)平臺(tái)，攀至屋頂，賞望遠(yuǎn)景。使用空間在西南、東北和東南角分設(shè)出入口，互不相擾：西南體量為以展廳、講堂和圖書(shū)吧為主的文創(chuàng)服務(wù)空間；東北體量以制作工坊、紀(jì)念品商店等特色產(chǎn)業(yè)體驗(yàn)1空間為主；基座下設(shè)置管理辦公用房和藝術(shù)家工作室，與服務(wù)區(qū)和產(chǎn)業(yè)區(qū)便捷相連。各組團(tuán)可分可合，會(huì)時(shí)各安其位，統(tǒng)一管理；會(huì)后亦可合而為一，共同運(yùn)營(yíng)。

開(kāi)放性之余，建筑又希望能實(shí)現(xiàn)某種內(nèi)在敘事，從而跟周邊環(huán)境中那些非自然的布景式建筑或景觀保持適當(dāng)距離。將建筑進(jìn)行兩分，“筑房擬山”，完成一種特定的景觀體驗(yàn)——單坡屋面賦予建筑以強(qiáng)烈的方向性和識(shí)別性，同時(shí)也完成了象征自然物的“山”與象征人工物的“房”之間的連接和互成：“房”以“山”為對(duì)景，位于東北側(cè)；“山”與“房”的基座相連，位于西南側(cè)。相似的坡頂形式，在室內(nèi)分化成兩類(lèi)不同特征的空間：西南側(cè)體量趴伏，空間呈現(xiàn)出洞穴般的模糊性；東北側(cè)間架清晰，暗合了傳統(tǒng)建筑的空間特征；半高的平臺(tái)將“山”與“房”既隔且連，使西南坡頂成為東北側(cè)“房”內(nèi)特殊的

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.
