对于经历过时间洗礼的老建筑，既要保留历史肌理，又兼顾形象提升、功能更新与周边环境协调性，该如何改造？

How to renovate old buildings that have undergone the baptism of history and time, while preserving their historical texture, enhancing their image, updating their functions, and coordinating with the surrounding environment?

拉法耶文化艺术中心的前身是租界时代位于辣斐德路（今复兴中路323号，1943年前旧名），由匈牙利建筑师拉斯洛·邬达克（Laszlo.Hudec）设计的辣斐大戏院。历史上的辣斐大戏院于1933年落成，经历过多次改造及一次拆除重建（2006-2009）。

Lafayette Culture Space traces its origins to the Lafayette Cinema, designed by Laszlo Hudec and completed in 1933. Over its history, the building underwent multiple functional transformations and a complete reconstruction (2006-2009).

虽按邬达克戏院样式重建，但存在诸多差异。其功能与形象已难以满足现代文化艺术中心的需求。并且建筑正立面沿街，三面环楼，东、西、南侧立面难以改造，主要改造临街面。因非历史保护建筑，业主希望结合数字技术进行整体改造。

▲历史信息，History information

Although the Lafayette Art and Design Center was rebuilt in the style of the Hudec Theater, there are many differences. Its function and image are no longer sufficient to meet the needs of modern cultural and artistic centers. The front facade of the building runs along the street and is surrounded by buildings on three sides. The east, west, and south facades are difficult to renovate, and the main focus is on renovating the street facing facade. Due to the non historical preservation of the building, the owner wishes to plan a comprehensive renovation incorporating digital technology。

▲改造前正立面，Original front facade

Lafayette立面改造以“城市剧场中的光影面具”为概念,由于拉法耶的正对面是住宅楼，不能够以LED灯或屏幕的形式直接展现，所以最终选择以穿孔铝板加亚克力的方式背投led点阵灯，使影像能够在夜间透出孔洞呈现出来。

The façade renovation is conceptualized as "The Shadow Masks in the Urban Theatre," Due to the residential buildings directly opposite Lafayette, direct use of LED lights or conventional screens was prohibited. The solution combines perforated aluminum panels with acrylic backing to house rear-projected LED dot matrix lights. At night, light illuminates through the perforations, allowing subtle yet vivid projections.

相邻两个折面之间的孔洞流向呈折角，以波浪形的流向覆盖整个立面，呈现流动的态势，如同时间的条纹，涂满光影变幻的立面。

The perforations between adjacent folded panels cascade in angular waves, sweeping across the facade in a rhythmic flow. Like streaks of time, they cloak the surface in ever-shifting plays of light and shadow.

将亚克力面板作为媒介，嵌入LED点阵屏或透明OLED，实现动态信息展示，利用亚克力的半透明性，若隐若现的透出原有立面细节，夜晚通过灯光强化历史线条。

除此之外，通过CNC雕刻或热弯工艺，在亚克力表面形成立体纹理（如艺术图案、数据可视化图形），搭配背面可变色LED灯带，白天为装饰性浮雕，夜晚转化为光影艺术墙。汤臣为麦当劳打造的栅格化门头便是这种艺术呈现。

In addition, through CNC engraving or hot bending processes, three-dimensional textures (such as artistic patterns and data visualization graphics) are formed on the surface of acrylic, paired with color changing LED light strips on the back. During the day, it is a decorative relief, and at night, it is transformed into a light and shadow art wall. The gridded storefront created by Donchamp for McDonald's is an artistic presentation.

麦当劳门头亚克力格栅造型，采用了汤臣高透明度亚克力，汤臣在其背面进行了精细的雕刻处理，赋予了格栅独特的纹理与形态。背面经过了喷砂工艺的特殊处理，使背后透的灯光呈漫散射效果，柔和不刺眼。

The acrylic grille design of McDonald's front door has been finely carved by Donchamp on its back, giving the grille a unique texture and form. The back has undergone special treatment with sandblasting technology, resulting in a diffuse scattering effect of light that is soft and not glaring

在制作工艺上，亚克力均采用背面固定，正面不显示任何固定件，整体柔美大气。这种独特的光影效果，不仅提升了麦当劳门店的夜间辨识度，更增添了一份雅致与现代感。

In terms of production process, acrylic is fixed on the back without any visible fasteners on the front, creating a soft and elegant overall appearance. This unique light and shadow effect not only enhances the nighttime recognition of McDonald's stores, but also adds a sense of elegance and modernity.
