Ivan Cheng’s design journey began with stage work. From the stage, he recognised early on: space is never merely a picture — light, scale, materials, rhythm and human movement collectively define how a space is experienced. This "stage‑minded thinking" later extended to interior design, furniture, installations and diverse spatial experiments. Over thirty years, his design mediums kept evolving, yet his focus on the perceptual experience of space has remained unchanged.

The exhibition unfolds a clear trajectory from complexity toward simplicity. His early works explored possibilities through rich materials, multi‑layered compositions and strong visual tension. With the passage of time and personal reflection, his design approach gradually embraced subtraction — not about doing less, but about gaining clearer insight into what deserves to be preserved. It ultimately distils into the aesthetic of "Clarity・Order" (澄・序) : Clarity stands for lucidity and transparency; Order stands for proportion, relationship and sequence. Once superfluous elements fall away, light‑shadow, materials, negative space, and the sense of distance between people and space become the true language of design.

Besides commercial projects, the exhibition also gathers Ivan Cheng’s sustained experimental creations spanning thirty years — furniture, material studies, forms, light‑shadow explorations and installations. These works are not created for the market; they function more like the designer’s private laboratory. It is within these free‑spirited explorations that design retains its sense of curiosity, as well as room for transformation.

Unlike conventional retrospectives that display works strictly in chronological order, this gallery space is conceived as an "experimental theatre". Artworks, lighting, moving‑image footage, texts and visitors’ own movement jointly weave the exhibition’s rhythm. What visitors encounter is not a flat chronological timeline, but echoes across different phases over thirty years: stage versus space, commerce versus experiment, past versus present, artworks versus life experience. The exhibition thereby turns into a design diary that one can step inside and read.

To return to Hong Kong is not to go back to the starting point. Instead, it means re‑examining the path he has travelled from where he stands today.

Three Decades of Design - A Diary is not a full stop. It serves as a record of the past, as well as the prologue for his next chapter of design journey.
