/ 小书店起源

Origins of the Small Bookstore

一间很小的书店起源于南京的秦淮河边，店主的理念是把书店最大限度留给客人，给不同人在不同的时间段提供一个温暖的地方。书店的店员是4只收养的流浪猫，墙面挂满了留言明信片。店里的书最开始由店主的旧书组成，随着客人越来越多，陆续收到了捐赠的新书、旧书。

A very small bookstore began by the banks of Nanjing's Qinhuai River. The owner's philosophy is to leave the bookstore to its guests as much as possible, providing a warm place for different people at different times. The shop's staff are four adopted stray cats, and the walls are covered with message postcards. The books in the store initially came from the owner's old collection, and as guests increased, new and used books were donated one after another.

/ 无意间的发现

An Accidental Discovery

项目在合柴1972创意园区。园区前身是安徽省合肥监狱，重新改造后如已成为了当地热门的文创园区。

The project is located in the Hechai 1972 Creative Park. The park used to be the Anhui Provincial Hefei Prison, and after renovation it has become a popular local cultural and creative park.

第一次来看场地时是陪同甲方看另外一个餐厅项目。现场无意瞥间路边的一栋废弃建筑，便好奇问了物业该建筑的状况和用途，得知是原监狱的看守塔，由于各种原因没有与园区一起改造荒废在了一边。随即便询问是否可以改造成为园区及附近居民服务的一家24h小书店。项目就这样启动了。

The first time we came to see the site was when we accompanied the client to look at another restaurant project. We happened to glance at an abandoned building by the roadside and asked the property about its condition and use. We learned it was the former prison guard tower which, for various reasons, had not been renovated along with the park and had been left derelict. We immediately asked whether it could be converted into a 24-hour tiny bookstore for the park and nearby residents. That’s how the project got started.

/ 现场勘探

On-site Survey

看守塔一层面积仅7平方米，二层巡逻平台可全方位俯瞰园区。同时窗户的栏杆上还保留了机枪架及监视孔，建筑本身功能非常清晰单一。

Upon entering the guard tower, the first floor measured only 7 square meters, and the second-floor patrol platform offered a panoramic view of the park. The window grilles still retained machine-gun mounts and observation ports, and the building’s original function was extremely clear and singular.

/ 检测加固

Testing and Reinforcement

建筑建于1997年，原始图纸已无法找到，必须重新地勘及结构检测后加固建筑主体。将原建筑4个角柱包加强角钢箍，加固二层楼板，加大屋顶混凝土梁截面，使得整体框架更为稳固。原始外墙部分使用高延性混凝土嵌缝工艺增加强度。

The building was constructed in 1997, and the original drawings could no longer be found, so new geotechnical and structural assessments were required before reinforcing the main structure. The original building’s four corner columns were wrapped with reinforced angle-steel hoops, the second-floor slab was strengthened, and the roof’s concrete beam cross-sections were enlarged, making the overall frame more robust. Parts of the original exterior walls used a high-ductility concrete joint-filling technique to increase strength.

/ “吊挂”结构形式

“Suspended” Structural System

在与结构设计事务所沟通后，为了最大限度减少新增楼荷载板同时又满足新功能，采用钢结构“吊挂”形式对其进行改造。

After communicating with the structural design office, in order to minimize the additional load of the new floor while still meeting the new functional requirements, a steel suspended structural approach was adopted for the renovation.

在加固后的原屋面混凝土梁上横向架设8根C型槽钢，使得对应的二层平台投影面尺寸向外延伸，满足了双人双向通道及座位阅读区。

On the reinforced original roof concrete beams, eight C-shaped channel sections were laid transversely, extending the projected plan of the corresponding second-floor platform outward to accommodate two-way circulation for two persons abreast and a seated reading area.

两根C型槽钢背靠背组合成H型后夹住纵向向下延伸的矩形实心钢吊杆，同时在原二层楼板混凝土梁的下方，从4个混凝土角柱伸出相同数量、尺寸、型号的C型槽钢夹住实心钢吊杆，使得8根槽钢及新增楼板吊挂在屋顶的钢梁上，形成了一个整体稳固的钢结构框架。

Two C-shaped channels were paired back-to-back to form an H-section that clamps rectangular solid steel hanger rods extending vertically downward. At the same time, beneath the original second-floor slab's concrete beams, C-shaped channel sections of the same quantity, size, and model extend from the four concrete corner columns to clamp the solid steel hanger rods, so that the eight channels and the new floor slab are suspended from the roof steel beams, forming an integral and stable steel structural frame.

利用建筑原始外墙窗洞增设了一个外挂悬挑阳台，串联室内外。

Utilizing the original exterior wall window openings, an externally mounted cantilevered balcony was added to link the interior and exterior.

/ 设计策略

Design Strategy

由于建筑西侧有两根高压电缆线离建筑主体过近，因此通过旋转屋面后再将4个角切除，形成四叶草的形状。

Because two high-voltage cable lines on the west side are too close to the building's main body, the roof was rotated and then the four corners were trimmed, forming a four-leaf clover shape.

新增楼板在钢结构上铺设木塑地板以减少荷载。将二层原始窗台下矮墙拆除后设计成了四面书架。阅读区书桌利用主体钢结构，将脚手架的“撑”与不锈钢吊杆的“吊”结合，形成吧台桌面。建筑四个角的位置设置了可开启的移窗，打开后形成无遮挡视野。

The new floor slab uses wood–plastic composite decking laid over the steel structure to reduce load. After removing the low wall below the original second-floor window sills, bookshelves were designed on all four sides. The reading-area desks leverage the primary steel structure, combining the "propping"of scaffolding with the "suspension" of stainless-steel hanger rods. Operable sliding windows were set at the building's four corners; when opened, they provide unobstructed views.

原始楼梯加固后用石膏板围合成室内管井，外侧作为书店留言墙。建筑南北两侧各增加1个户外平台区，分别满足咖啡售卖及书店、园区定期举办活动。

After reinforcing the original staircase, it was enclosed with gypsum board to form an interior service shaft, with the exterior serving as the bookstore's message wall. An outdoor platform area was added to both the south and north sides, respectively accommodating coffee sales and regular events organized by the bookstore and the park.

/ 愿景

Vision

通过对结构、材料及功能的重新构建，将原来的监狱看守塔转变为新的场所：一间很小的书店，为周边街区的每一个人敞开。虽然现在的墙是空白的，假以时日希望小卡片依旧能挂满，因为卡片上诚挚的话语是每一个人心中的希望。

Through a reconstruction of structure, materials, and functions, the former prison guard tower has been transformed into a new place: a very small bookstore, open to everyone in the surrounding neighborhood. Although the walls are blank for now, with time we hope they will once again be covered with little cards, because the sincere words on those cards are the hope in everyone’s heart.
