林建筑
Forest Building

林建筑項目位于北京通州運河森林公園，提供餐飲、聚會、展覽、會議等服務。設計受樹木形狀啟發，最初的想法是創造一個樹下的空間，那么樹的枝干將相互連成一種結構形式并在其遮蔽之下形成空間。這樣在公園里，人工的森林將與自然的樹木共舞。

以柱子為中心并伸出四條懸臂梁的樹一般的基本單元，在合理的高度變化控制下重復組合成結構。平面基于有些曲折的規律格網，它的邊界自由，便于繞開場地現存樹木并獲得分期施工的靈活性。

建筑座在“飄浮”于地面的混凝土平臺上，這樣一方面有利于木結構防潮，另一方面，將機電設備服務層布置于平臺之下，使屋頂下部解放出來，還原為純粹的結構和空間。

建筑主體材料為木和夯土，它們的自然質感呼應了場地中的泥土與樹木。這些材料可以自然呼吸，有效調節室內外的相對濕度溫度，將來也可自然降解回歸自然。立面上木和夯土墻間以玻璃幕墻填充，為室內使用者提供了同時身處人工與自然森林間的感受。

Located in a park full of trees by the Grand Canal River on the east side of Beijing, the project started without a clearly defined program. The client visioned the space to be flexible for different functions (restaurant, bars, event space, gallery, office, etc.). Inspired by No-stop city, a utopian urban design proposed by Archizoom in 1960s based on indeterminism, Forest Building explores a spatial system generated from additive units responding to the uncertainty of program, as well as structural form and construction system responding to the character of the site.

When the program doesn’t give much to initiate the design, the architects examined the site to find a starting point to capture the sense of place. The river and the trees were the strongest character of the site, so the idea started to emerge: to create a place where people can sit under the tree and enjoy the view of the river—just like what everyone does in a park, even without architecture. This became the beginning point. Consequently, a base unit was developed. By organizing it in a grid system, there generates the overall form. Later on, the structure, material, landscape, mechanical system, drainage, all these elements are conceived and developed following the original intention.

The structure is made from the repetition of a basic unit, a tree like column with four cantilevered beams at varied heights. The plan is based on a grid system that is flexible enough to adapt to the site and existing trees. Such flexibility also makes it possible to break down construction into a number of phases.?The structure is elevated by a floating concrete platform, which protects the glulam structure from moisture. At the same time, the utilities run underneath the concrete floor so that the wood ceiling is free to express the structure and space purely.

The architecture is mainly constructed from glue laminated wood and rammed earth. These natural materials could adjust the relative humidity and temperature of indoor and outdoor areas, and will biodegrade in the future. Clear glass windows fill in the space between wood columns and rammed earth walls, inviting people inside to experience the manmade forest and the natural forest outside at the same time.
