926 Craftsman Museum

926工匠博物馆与926公园位于杭州钱塘江大桥东南侧，紧邻闻涛路，可远眺大桥与江景。作为滨江区12公里滨水公共空间改造项目的一部分，博物馆选址于原管理用房区域，以最小干预原则介入，保留东侧大树形成居民活动广场，旨在以工匠精神重塑区域特质。

建筑形态由“工匠之手”捏合的屋脊指向钱塘江大桥与远山，地面隐藏的“926”图案重塑微地形，围合出院落空间。屋面采用6mm厚阳极氧化铝折叠板，通过CNC数控加工与现代造船技术实现，形成双曲面折叠屋顶——侧面挑檐、中部滑落至地面，以现代形式诠释江南传统。

辅助空间置于地下一层，释放首层形成纯净展览空间。铝板屋顶塑造丰富空间体验：屋脊留出四个方向窗洞应对不同城市景观；两个随地形起伏的月牙形窗引入庭院景致；折叠屋顶形成的两个三角形天窗成为视觉焦点，带来变化的光影效果。

结构上，35m×35m的展厅采用钢桁架大跨度系统，仅在外围设钢柱，实现无柱室内空间。立面为满足轻盈通透要求，采用极小截面（80×160、100×150）密柱作为幕墙立柱，柱间钢拉杆直径仅50mm，最大程度保证建筑通透性。轻质结构确保室内空间流动，展现建筑与自然的融合，简洁空间凸显技术外壳，含蓄回应工匠精神。

926 Craftsman Museum – The 926 Craftsman Museum and the 926 Park are located on the southeast side of the Qiantang River Bridge. They are adjacent to Wentao Road, where you can easily see the bridge and the river. It is a part of the 12-kilometer waterfront public space renovation project in the Binjiang District of Hangzhou, undertaken by the Original Design Studio of TJAD. The Qiantang River Bridge was completed and put into use on September 26, 1937. It is the first double-decker truss girder bridge across the Qiantang River in Hangzhou, a milestone in the history of Chinese bridges. It was presided over the design and construction by Mr. Mao Yisheng, a Chinese bridge expert and a founder of China’s modern bridge industry. The Craftsman Spirit Attributes – To commemorate the completion day of the Qiantang River Bridge, September 26th was established as “926 Craftsmen’s Day” in Hangzhou. So far, more than a hundred talents with superb skills have been recognized as “Hangzhou Craftsmen.”

The 926 Craftsman Museum, built on the southeast side of the Qiantang River Bridge, has filled the vacancy for a museum displaying the spirit of Hangzhou craftsmen. The Park is close to the Qiantang River Bridge, where residents like to gather for activities. However, the content could be more varied while the facilities are degenerate. In order to reduce the impact on the environment, the museum is located within the old management building area. The large trees on the east side of the building have been preserved, forming a square for residential activities. The site is located on the west part of the 12-kilometer waterfront public space renovation project. Guided by the design principle of limited intervention, we hope to improve the quality of public spaces from point to area and reshape the regional characteristics with the spirit of craftsman.

The Shaping of Modern Forms – The roof ridge pinched by the “hands of craftsmen” points to the Qiantang River Bridge on one side and the distant mountains on the other side. The “926” figure hidden on the ground reshapes the micro-hill topography, forming the courtyard space and integrating the indoor space with the courtyard. The polished double-layer 6mm thick anodized aluminum folding plates adopt CNC manufacturing technology and draw on modern shipbuilding technology. We hope to achieve a time-space dialogue between craftsmen in different eras. The folded roof forms a cornice in the side and slides down to the ground in the middle, enclosing a courtyard space, interpreting the Jiangnan tradition in a modern form.

The service spaces, offices, equipment rooms, and other auxiliary spaces are placed underground, freeing up the space on the first floor. The cavity between the double-layer skins was used for piping and equipment, creating a transparent, pure, and integrated exhibition space. We hope to achieve a rich spatial experience by shaping the aluminum plate roof: on the one hand, the shape of the roof ridge leaves windows in four different directions to cope with different urban landscapes; on the other hand, the two crescent-shaped windows that undulate with the terrain are looking into the courtyard; at the same time, the folded roof forms two triangular skylights, which serve as the visual focus of the entire space and introduce a changing light and shadow effect.

Lightweight Construction – The museum covers an area of about 35mX35m, with a total area of 1100 square meters. The long-span roof adopts a steel truss system. Steel columns are only installed on the outermost periphery of the structure, creating a large, column-free indoor space. Considering the requirements of lightness and transparency of the facade, dense columns are used as curtain wall columns, with extremely small cross-sections (80×160, 100×150). The diameter of the steel tie rods between columns is only 50mm, ensuring the transparency of the building to the greatest extent. The light structure ensures a flowing indoor space, revealing the integration of architecture and nature. The simple space maximizes the display of the technological shell and implicitly responds to the spirit of craftsmanship.
