古南街东依蜀山，西临蠡河，曾是丁蜀镇水上通道的进出端口，也是紫砂文化的发源地。根据旅游策划和城市设计，南入口节点是古南街的“街口”。

张家老宅位于古南街口三面阔房屋的最南一间，呈小面宽大进深的狭长状，东侧是上蜀山的小道，具有开阔的景观视野和良好的建筑展示面。建筑新的功能定位为以紫砂文化交流和展示为主、兼具茶室的公共建筑。改造设计保留古南街的入口供展厅使用，增加了东院墙上的新入口，避免了不同功能流线的干扰。建筑沿街界面的处理考虑到与相邻开间的相似性和连续性，仅对门窗洞口的尺寸及开窗样式进行推敲。山墙南端结合展示功能拆除局部砖墙，展露内部木屋架，与玻璃、钢框形成和谐对比。

改造设计始终关注既有建筑的结构安全性与保温隔热、自然通风等性能化提升，这也始终贯穿于整个古南街建筑的改造更新过程。□

2 南入口/South entrance

With the Shushan Hill to the east and the Lihe River to the west, Gunanjie Street used to be the main port of the waterway in Dingshu, and also the birthplace of Zisha culture. According to the tourism planning and urban design, the south entrance node is the street opening of Gunanjie Street.

The old Zhang family house is the southernmost of the three-bay houses at the entrance to Gunanjie Street, and is a long and narrow space with small width and large depth, connected to a trail to Shushan Hill on the east side. The house has a grand view and a dominant architectural façade, and its new function is a public building for Zisha cultural exchanges and exhibitions, as well as a tea room.The renovation design retains the entrance along Gunanjie Street, adds a new entrance to the east wall of the courtyard, avoiding interference with different functional flows. The design considered the continuity with the adjacent houses, the building's façade facing the street only adopted deliberate changes in the size of the door and window.Combined with the display function, the brick gable wall was partly removed at the south end, and the internal timber roof truss was exposed, forming a harmonious contrast with the glass and steel frames.

The renovation design always pays attention to the existing buildings' structural safety and performance improvement such as heat preservation and natural ventilation throughout the renewal process of the entire Gunanjie Street. □

黄居正：江南的名镇、古镇不少，虽同处吴地水乡，却因漫长的历史积淀，形成了各具特色的聚落形态和文化特征，所谓“出门三五里，各地一乡风”。然而，几十年中国经济的快速发展，使古镇之间原本微妙的文化差异被迅速抹平，并为崇尚“速食”的消费主义所荡涤，消逝在急功近利的旅游开发大潮之中。2020年8月，当我第一次来宜兴丁蜀镇时，感受到古老的陶都依然流淌着鲜活的传统，反倒是有些诧为意外。……
