Antonio Citterio Patricia Viel and Partners envisioned a sculptural form for 99 Bonham, using sleek proportions that resemble the scale of an industrial design project. The monolithic glass façade and reflective tiles bring an almost abstract quality to the building, like that of a desirable object. The interior design brings this theme to a human scale with a range of grey tones as well as an interplay between shiny and neutral surfaces. 99 Bonham exemplifies a completely integrated design, from the conceptual approach of the exterior to every detail of the interior. It creates a striking stiletto silhouette within the Hong Kong skyline, while offering a quietly elegant living environment.
