成都交子大道是一条两公里长东西向的林荫道，两侧各有约25米宽的人行景观空间，其中散布着二十余个规模几百平米不等的服务驿站，本案即为位于N4-3地块的餐饮建筑。
The avenue of Jiaozi, is a grand boulevard in Chengdu that stretches two kilometers from east to west, with a 25-meter wide of landscape space on both sides. The restaurant is one of the twenty service stations that dots the boulevard.

基地南侧面向城市道路，北面隔着车道为高层住宅塔楼，往东可以远眺交子大道端点的双塔。初次来到场地我们感受到的便是都市的车水马龙与水泥丛林的紧迫感。我们直觉地希望能设计一栋充满自然气息的建筑，一个从建构形式到材料选择上都易于亲近的空间，在紧张忙碌的环境中为人们营造一个放松闲适的用餐场所。
The site is located at the heart of the city, facing the busy street on the south and the soaring high rises on the north, and looking afar the twin towers at the end of the avenue. The sense of place is busy and intense, on first visit we immediately envisioned a proposal that would bring a breath of nature. Working with materials and tectonics that evoke a sense of nature, we try to create a relaxing and approachable setting for people to sit down and enjoy the food.

空间概念
The Architectural Concept
餐厅面积约600平米，南侧的两层用餐区最大化地利用景观步道，厨房与后勤空间则靠北集中。场地南面的镜面水池是进入建筑之前重要的过渡空间，水面映射着舒展的屋面与天空，让人们在浮光掠影中放松心情。
The restaurant consists of a double-story dining space on the south and a concentrated back-of-house space on the north. A reflection pool is designed alongside the south façade and becomes a transition from the street to the entry. The water reflects the roof and the sky beyond and calms the mind of diners.

建筑的量体希望建立起坡屋顶的传统四川民居与简洁利落的现代城市之间的对话。餐厅东立面延续了四川传统木结构建筑倾斜的屋顶轮廓与立面肌理，西立面衔接了交子大道周边方整的建筑语汇。两者迥异的形体由一个扭转的屋面自然地连接在一起。屋面的轮廓轻如羽翼，动态起伏的双曲面顺着蜿蜒的屋脊线延展，轻盈地覆盖着下部的餐厅与景观，给予用餐的人们自由奔放、充满动感的空间氛围。

The mass of the project plays with a dialogue between the vernacular architecture and the contemporary cityscape. The east façade celebrates the traditional pitched roof of Sichuan residence while the west façade responds to the context in a rectangle profile. A twisting roof bridges the two sides and acts as a dynamic transition in between. The sprawling surfaces of double-curved roof stretch along a curved ridge in the middle and hover over the dining space and landscape underneath. The profile of the roof is dynamic and light, like the spreading wings of a bird that gently falls on the street.

结构体系
The Structure
建筑的结构为钢木混合结构。斜向交叉的网格状胶合木木梁顺应双曲面形体排布，由室内一路延伸至檐口，形成了人工建构的自然与室外绿意的对话。为了增加稳定性，钢柱在二层楼板以上分叉，并以十字型钢梁搭接到木屋顶两个网格的中心点，形成树枝般的结构构件。
The structure of the project integrates steel columns and timber roof. Laminated timber beams adapt to the double-curved surfaces and extend from inside to outside in a diagonally crossing grids. The continuous pattern of structure unifies the interior and exterior and creates a dialogue between constructed nature and the landscape. To enhance the stability of the structure, each steel column is connected to two center points on grid with cross-shaped transfer beams, resulting in a unique branch-like structural elements on second floor.

本案结构设计的最大挑战在于如何实现屋面在南侧超过4米的悬挑，建筑在前排钢柱的基础上增加了四根斜柱以支撑木梁，使屋面能够低垂于镜面水池之上而无需落柱，同时形塑了沿着幕墙的狭长挑空空间，让在一层的人们也能看见二层生动的木结构。

The biggest challenge of structural design is to achieve the over 4-meter cantilever on south, where the curtain wall recedes. Four inclined columns are added from the foundation of front columns to ensure that the roof floats upon the reflection pool without any support on the outside. The inclined columns also shape a linear void space along the curtain wall, through which visitors from the lower level have a chance to appreciate the dynamic roof.

外围护表皮系统
The Envelop
建筑立面设计尽可能的通透以突出木结构在室内外的连续感受。南北侧的玻璃幕墙呼应了屋顶木梁的走向，自然而然地形成了连续转折的动态轮廓。在室内灯光的照亮下，街上的行人可以从外侧透过玻璃清晰地看到整个木屋顶。
The façade design aims to achieve maximal transparency to enhance the continuity of timber structure from inside to outside. The curtain wall on south and north follows the crossing grid of the timber beams resulting in a continuous zigzag profile. When the restaurant is illuminated from inside, the timber structure is revealed to pedestrians through the glass.

金属屋面采用了蜂窝幻彩铝板，在阳光下反射环境呈现出渐变的光泽。铝板以层层叠落的形式包裹着动态的屋面，每层表皮之间的断面采用乳白色的亚克力与LED灯，在夜晚它们发出柔和的灯光将屋面层层晕染。
The roof utilizes the aluminum honeycomb panels that reflects the environment and presents gradient color under the sun. The aluminum shell adapts to the form of roof and splits into multiple cascading layers. Translucent acrylic panels and LED lights are used at the splits between the layers and they render the roof with soft glow at night.
