结构解构与空间重塑：建筑师巧妙地将原有建筑的框架结构进行解构，通过引入吊顶系统和重新排布的柱群，赋予了空间全新的秩序。原先单调的框架结构被转化为丛立的柱群，支撑起高低错落的体量，为空间注入了活力。同时，对主入口平台和西侧屋顶体量的改造，强化了建筑的公共性，使其更易于与周围环境互动。这种结构上的解构与重塑，为后续的空间设计奠定了坚实的基础，也为书店赋予了独特的视觉特征。

木梁与自然对话：项目核心的亮点在于木梁群的运用。设计师引入了木双梁系统，贯穿并夹住混凝土柱列，在空间中建立起水平向的秩序。这种设计不仅在结构上增强了建筑的稳定性，更重要的是，它创造了一种与自然对话的独特方式。胶合松木梁与混凝土柱的结合，以及向外悬挑的设计，将室内空间与室外景观紧密相连。梁间的缝隙更是巧妙地兼顾了空调回风和照明设备的集成，展现了设计的精巧与实用性，使得建筑真正融入了周围的自然环境。

空间穿插与环境融合：建筑师通过“书塔”和“水榭”的设计，实现了空间上的纵向穿插。书塔的层叠结构为读者提供了多样化的阅读体验，而面向湿地的窗口则将自然景观引入室内。水榭的设计则更进一步地与环境融合，压低的坡顶和下沉的地面共同营造出一种融入湿地的氛围，灰色钛锌板屋面与银色内饰的巧妙结合，强化了水面反射光线的效果，使得湿地“进入”室内。书梁的交错设计，以及悬吊披檐、立体错动的玻璃界面等细节，都创造了建筑与自然的多个中介性场域，最终实现了建筑与环境的和谐统一。

The project is located at the northern end of Xixi Wetland Fudi. The original building was an office building from twenty years ago - with a U-shaped symmetrical layout and a complex combination of functional spaces. The building is elevated on the wetland, and the water courtyard surrounded by three wings is closed and passive. The design requires exterior renovation and interior design to transform it into a bookstore.
项目位于西溪湿地福堤的北端。原建筑是二十年前的办公楼建筑 —— U 型中轴对称的布局，功能空间组合的错综体量。建筑架空于湿地上，三翼环抱的水院封闭而消极。设计需对其进行外立面改造及室内设计，将其转化为一处书店。

The first floor is planned as a space that surrounds the water courtyard and is horizontally connected. The vertical main space on the west side accommodates book exhibition and sales functions, while the book bar on the north wing serves as a coffee reading area; The south wing is the reading salon area, connected to the second floor landscape terrace through outdoor stairs. Peel off all the enclosing walls, leaving behind a chaotic and meaningless concrete frame structure. The intervention of a series of new "structural groups" forcibly assigns a new order to the originally chaotic structure, transforming it into a spatial field deeply associated with nature.
一层被规划为环抱水院、水平连通的空间。西侧纵向主空间容纳了书籍展销功能，北翼书吧为咖啡阅读区；南翼为阅读沙龙区，通过室外楼梯与二楼景观露台相连。剥离掉所有围护墙体，留下的是一组混沌而无意义的混凝土框架结构。一系列新“结构群”的介入，给原本混沌的结构强行赋以新的秩序，使其转化为与自然深度关联的空间场域。

01 Disassembly of the original frame

In response to the intricately arranged roof beams and slabs in their original state, the original frame structure was disassembled into a cluster of columns that supported the staggered volume by introducing a suspended ceiling system that accommodated mechanical and electrical equipment.. On the existing curved lane of the main entrance platform, a staggered pedestrian walkway made of cement strips has been laid, transforming the original vehicle platform into an entrance space with diverse scales and directional changes. The simplification and adjustment of the volume of the west roof, along with the retreat of the colonnade into the facade, have transformed the original axis symmetric facade into a horizontal suspended volume, thereby enhancing the public nature of the building.
01 原框架的解体

针对原状错综的屋顶梁板，通过引入容纳机电设备的吊顶系统进行梳理，原框架结构被解体为：丛立的柱群，支撑起高低错落的体量。主入口平台的既有弧形车道上，铺设了由水泥条构成的错角形人行栈道，将原车行平台转化为尺度多样、方向变换的入口空间。西侧屋顶体量的简化调整，与立面退入的柱廊，将原中轴对称的立面调整为水平向的悬浮体量，从而强化建筑的公共性。

Weight of 02 Wooden Beam Group

For the original 6 * 6-meter frame column grid, a wooden double beam system has been introduced.. Each group of wooden double beams passes through and clamps the concrete columns, establishing a horizontal spatial order perpendicular to the water courtyard and connecting the inside and outside of the U-shape. The structure is made of glued pine beams, which are structurally fixed to concrete columns through concealed support plate nodes, and suspended to the outside at various locations. The gap between the double beams serves as an integrated strip for air conditioning return air and column lighting equipment.
02 木梁群的重

针对原 6*6 米的框架柱网，木双梁系统被引入。每组木双梁贯通性地夹住混凝土柱列，建立起垂直于水院、连通 U 型内外的水平向空间秩序。结构用胶合松木梁，通过暗托板节点与混凝土柱子进行结构性固定，并在各处向室外悬挑。双梁间的缝隙兼作了空调回风、柱列照明的设备集成带。

分析图

In the horizontal spatial field formed by the wooden beam group, two vertical spatial disturbances were further designed, one is the book tower leading to the sky, and the other is the water pavilion leading to the wetland, allowing the natural landscape to intervene in the bookstore space in a more three-dimensional manner.
在木梁群构成的水平向空间场域中，设计进一步做了两处垂直向的空间扰动，其一是导向天光的书塔，其二是引向湿地的水榭，使得自然景观能够更为立体化地介入书店空间。

03 Raised Book Pagoda

A "Book Pagoda" has been added to the high volume in the southwest corner.. The two nested circular interlayers form a cross-sectional pattern similar to a theater, with staggered scales providing seating and reading spaces at different elevations. The window facing east introduces the greenery of the wetland in the distance.
03 抬升的书塔

西南角高体量内增设了一处“书塔”。层叠嵌套的两圈环形夹层构成了类似剧场的剖面模式，错层尺度刚好提供了不同标高的坐读空间，朝向东侧的窗口引入了湿地远处的绿意。

The mezzanine of the book tower breaks the conventional treatment of floor slabs. The steel beam mezzanine with a cross shaped layout is erected between the concrete columns and suspended downwards. The top surface of the I-beam is level with the wooden floor, presenting a horizontal element that is homogeneous with the wooden beam: at the end of the vertical space, the beam group is stacked downwards to release natural light. The silhouettes of people inside the book tower were intercepted by horizontal wooden beams, creating a floating landscape.
书塔夹层打破了常规楼板的处理，井字形布局的钢梁夹层架设在混凝土柱间并向下悬吊，工字钢顶面与木地板齐平，被呈现为与木梁同质的水平向要素：在纵向空间尽头，梁群向下层叠而泻下自然光线。书塔内人们的剪影被水平木梁截获，成为漂浮的风景。

04 Sinking Water Pavilion

The irregular glass volume of the original building facing the water courtyard has been replaced with a single sloping roof.. The geometric potential of planar oblique lines is fully utilized, naturally forming the slope crest where the profile gradually descends; At the same time, the original floor slab was partially knocked out and transformed into a sunken near water area. The depressed roof and sunken ground work together to create a "water pavilion" that blends into the wetland. The exit staircase provides a reading space facing the wetland and sitting on three sides.
04 下沉的水榭

原建筑朝向水院的不规则玻璃体量被替换为一处单坡顶。平面斜线的几何潜力被充分利用，自然地构成了剖面逐渐压低的坡顶；同时原楼板被局部敲除，改造为一处下沉近水区域。压低的顶面与下沉的地面共同作用，成为了一处融入湿地的“水榭”。退台阶梯提供了朝向湿地、三面而坐的阅读场所。

At the corner of the U-shaped plane, the water pavilion is "ceded" to the water courtyard, which not only creates a horizontal twist in the indoor space, but also obtains a vertical force directed towards the wetland water surface, strengthening the wetland's role in the internal space. The roof of the water pavilion is made of gray titanium zinc plate, and the ceiling is sprayed with silver metallic paint as a whole: it not only strengthens the spatial force of the slope top as an object pressing down on the water surface, but also highlights the subtle reaction of silver to the reflection of ambient light, as a reflection of the natural water light background. The huge water pavilion ceiling reflects rippling water waves every morning, and the wetland "enters" the interior in this peculiar way.
在 U 型平面转角处，将水榭“割让”给水院，不仅对室内空间产生了水平方向的扭转，同时获得引向湿地水面的垂直力，强化了湿地对于内部的空间作用。水榭屋面采用灰色钛锌板，顶棚则整体喷涂以银色金属漆：既着意强化坡顶作为物体压下水面的空间力，又突显银色对环境光反射的微妙反应，以作为映射呈现自然水光的背景。庞大的水榭顶棚在每天上午反射出潋滟的水波纹，湿地以这样奇特的方式“进入”室内。

05 Suspended eaves

The "Construction Method" records a type of Song style water facing exterior eaves decoration component - "Barrier Sun".. The design provides a contemporary translation of this traditional prototype: wooden beams break through the boundaries of the building and protrude outward. The eaves are suspended on both sides of the wooden beams by pull-up suspension rods, and are supported in the middle by a downward sloping rod, thus forming a special water facing building interface. The eaves are constructed using materials similar to those used in water pavilions.
05 悬吊的披檐

《营造法式》中记载过一类宋式临水外檐装修构件 —— “障日䈳”。设计对该传统原型进行了当代转译：木梁突破建筑边界向外出挑，披檐两侧由上拉的吊杆悬挂在木梁上，中间由一根下接的斜杆辅助支撑，从而构成了特殊的临水建筑界面。披檐采用了与水榭相似的材料构造。

As an intermediary element of the building's adjacent water boundary, eaves have two functions. One is to adjust the indoor lighting, while blocking the glaring direct sunlight, the silver ceiling provides soft diffused light, forming a more suitable indoor space for reading; The second is to adjust the spatial scale, with the lowered eaves blocking out the interference of tourists from Fudi and the two wings of the water courtyard, allowing people's indoor gaze to be directed downwards towards the wetland water surface, enhancing the perception of the building being elevated above the water. The overhanging eaves of wooden beams, the elevated table and chair components between columns, the three-dimensional staggered glass interface, and the foldable windows that can be fully opened together form multiple intermediary fields between architecture and nature.
披檐作为建筑邻水边界的中介性元素，有两点作用。其一是调节室内光线，在遮挡刺眼的直射阳光同时，银色顶棚提供了柔和的漫射光，形成更适宜阅读的室内空间；其二是，调节空间尺度，压低的檐口屏蔽掉福堤的游客及水院两翼对视的干扰，让人在室内的视线朝下导向湿地水面，强化建筑架空于水上的场所知觉。木梁悬吊的披檐、柱间架空的桌椅构件，与立体错动的玻璃界面、可整面打开的折叠窗, 共同形成了建筑与自然之间的多处中介性场域。

06 Interlocking Book Beam

The bookshelf is designed as a specific structural element that parasitizes between columns - a transparent "book beam", hoping to allow readers to see both books and scenery.. We collaborated with the structural engineer Zhang Zhun to create the "Book Beam" structural device: a combination structure consisting of horizontal wooden beams and vertical stainless steel plates stacked horizontally to form a composite structure: glued laminated wood and European pine plates are combined to form an I-shaped section, supporting a structural span of up to 6 meters, while vertical stainless steel plates connect the wooden beams into a structural whole, achieving torsional resistance in the plane. The book beam is suspended by structural suspension rods on both sides and fixed to the columns, achieving a "beam" shaped stress mode.
06 交错的书梁

书架被设计为寄生于柱列之间的特定结构要素 —— 通透的“书梁”，希望让读者既能看到书籍、又能看到风景。我们与结构师张准进行合作，创造了 “书梁”结构装置：以横向水平木梁与纵向不锈钢板进行水平层叠，成为组合结构：胶合木和欧松板组合成工字型截面，承担长达 6 米的结构跨度，而纵向不锈钢板则将木梁联结为结构整体，实现平面内的抗扭。书梁由两侧的结构吊杆悬吊而与柱子固定，实现“梁”型的受力模式。

The six sets of book beams are staggered in height between the columns, forming a rich spatial interlocking effect with the wooden beam group. They float in the white space, defining a group of fields with ambiguous boundaries and open to nature. Xixi Wetland, as a secondary urban wetland in Hangzhou, is a place for nearby residents to take daily walks and ride bicycles. We have built a transparent and open bookstore on the wetland, allowing people to read books and nature at the same time, becoming a public place embedded in the natural life of the city.
六组书梁在柱列之间高低错落，与木梁群形成丰富的空间交错效应。它们漂浮于白色的空间中，限定出了一个个边界暧昧、朝向自然打开的场域群。西溪湿地作为杭州的城市次生湿地，是周边居民日常散步、骑行的场所。我们在湿地上构建出一座透明而开放的书店，让人们同时阅读书籍与自然，成为嵌入城市自然生活的公共场所。
