- Architect Gary Chang converted a 32 sqm Hong Kong flat into 24 configurations.
- The design utilizes sliding partitions, ceiling steel tracks, and hydraulic beds.
- Inspiration stems from his childhood lack of space and local street hawkers.
- The concept later influenced commercial residential and hospitality projects.
In Hong Kong, architect Gary Chang has turned a compact 32-square-meter apartment into a series of dynamic living environments using sliding partitions, fold-down elements, and ceiling-mounted tracks. This setup accommodates up to 24 different room configurations. The project serves as a long-running exploration into how domestic spaces can be reprogrammed, questioning whether a small physical footprint inherently restricts one's lifestyle.
Chang's journey began when he moved into the apartment in 1976 at the age of fourteen, sharing the home with his parents, three sisters, and a sub-tenant. Without a dedicated bedroom, Chang slept on a wooden bench in the central corridor after the rest of the household went to sleep. This formative experience challenged his perception that domestic functions must occupy permanently defined rooms.

The architect's design practice evolved through several iterations of the apartment, transitioning from a cellular layout to an open-plan layout, then utilizing curtains before completing the mechanized Domestic Transformer in 2007. Chang concentrates utilities and storage along the perimeter, leaving a flexible central area that can be reconfigured repeatedly.
The mechanical system operates overhead, with primary sliding partitions suspended from steel tracks fixed to the concrete ceiling. This keeps the floor clear and allows heavy storage walls containing appliances, clothing, and media to glide effortlessly. Lightweight honeycomb aluminum panels and a hydraulic bed further maximize the usable floor space.
Chang's approach to kinetic architecture addresses the severe spatial constraints of densely populated urban areas like Hong Kong. By re-engineering domestic interiors through mechanical flexibility, the project demonstrates how limited square footage can support diverse daily activities without requiring a permanent physical expansion.
Furthermore, Chang draws inspiration from local Hong Kong street hawkers, whose stalls expand during business hours and contract afterward. Applying this urban principle to domestic scale, his walls, storage units, and screens act as components in a synchronized choreography of space.
