引子 | Preface

2019年中国北京世界园艺博览会已胜利落下帷幕，展会期间我们为园区建造了一栋供游人驻足、休憩、赏景的滨水建筑，建筑选址于妫汭湖畔，我们将其命名为“延波小筑”，实践并创新传统文人意趣。

The 2019 World Horticultural Exposition in Beijing, China has come to a successful end. During the exhibition, we built a waterfront building for visitors to stop, rest and enjoy the scenery. The building is located on the side of Guirui lake. We named it ” Water front graceful pavilion ” to practice and innovate the traditional culture and interest.

建筑场地为湖岸缓坡，茂林掩映、隔水与园区焦点建筑中国国家馆毗邻。站在中国馆二层露台北望，远山近湖，层林叠嶂，游人隐现于湖岸岛屿之间，颇似一幅动态的中国古典山水画卷。为传达中国传统空间设计理念，我们追寻画坛巨匠董源画作中水岸山林，亭舟隐现的山水人居图景，敲定了“行望居游”的画意式设计策略。

对于建筑形象，世园会管理方提出要重点考虑中国馆二层北露台视点，从这里向北远望，滨水建筑要能自然融入到林、岛、桥、阁，甚至关照更远的海坨山余脉。而自然的融入也正是我们想要达到的设计状态，我们更希望基于自然建造的设计观，找寻一个充满想象力的本土答案。

The construction site is a gentle slope on the lakeshore, surrounded by dense forests and separated by water, adjacent to the National Pavilion of China, the focus of the park. Standing in the north of the second floor terrace of the China Pavilion, with mountains and lakes in the distance and forests in the layers, the tourists are hidden between the islands on the lake bank, which looks like a dynamic picture of Chinese classical landscape. In order to convey the concept of Chinese traditional space design, we pursue the landscape and human settlements in the paintings of Dong Yuan, a great painter in the world of painting. We have determined the design strategy of “walking, watching, living and traveling”.

For the architectural image, the Coordination Bureau of the world horticultural exposition proposed to focus on the view point of the North terrace on the second floor of the Chinese Pavilion. From here, the teahouse building should be able to naturally integrate into the forest, island, bridge, pavilion, and even take care of the more distant Haituo mountain. And the integration of nature is exactly the design state we want to achieve. We hope to find an imaginative local answer based on the design concept of natural construction.

世园会的非典型屋顶营造 | A typical roof construction of the World Horticultural Exposition

中国传统营造中最具想象力的当属造园。园林与书画同源，造园不是孤立的建造，而是构建一个相互联系的语境，山水树石、径庭屋宇彼此因借，既独立成型，又对话相融。我们的设计截取中国传统山水画中屋舍的双坡屋面，在场地内勾画出一道似是而非的屋顶，将其覆盖于场地之上，状如水边一处山坡，形成陂池相映的格局。山墙面完全打开，将屋宇下的行旅流线完整揭示，穿越树林、庭院、竹堂、月台四组空间。从湖对岸看去，游人好似由屋中进入，山中穿出，直抵水边，完成行、望、居、游的感官体验。建筑似山非山，似屋非屋，与自然促膝交谈，又各得其所。房屋朝向选择一坡朝向主路，保持正常的檐口高度，另一坡朝向湖面，屋面直接向水面延展，几乎逼近地面。檐口的高低之态，远就永宁阁，近接妫汭湖，呼应成趣。
