Xtra-Herman Miller shop in shop 
Stacy Peh 


Our design inspiration comes from Herman Miller’s core products; Work Chairs. Herman Miller’s extensive range of work chairs produced over the years embodies their philosophy, culture and aspirations; a desire to constantly innovate, integrate technology with design and produce high quality, purposeful, human-centred products.

Learning from the design processes of the work chairs, which combines formal, structural and material innovation based on the research of Ergonomics to create a surface that moulds comfortably to the human body, our proposal seek to develop a “skin” for the Herman Miller Store that is “moulded” to its host – Xtra. Four central ideas guide our design process.


The Herman Miller store is expressed as a porous plywood envelope forming an independent entity that plugs into the shop space of Xtra. This lightweight envelope allows visual links yet maintains the identity of both stores.


Just as the Herman Miller work chairs are designed to adapt to our postures and movements, the Herman Miller skin is moulded to adapt to existing structures and customer movement patterns. The continuous surfaces forming the façade, walls, ceiling and entrances invite customers into the store and guide them through the experience.


The complex envelope is pieced together using simple three-legged plywood component panels designed with interlocking lap-joints. The panels are “stitched” together forming the rigid, woven double-layered envelope. The majority of the panels are standardized to three varying sizes to achieve greater efficiency for fabrication and assembly. Customised panels are limited to the weaving as well as doubly-curved surfaces. There are approximately 4,000 wooden pieces that completes the whole design.

Digital Fabrication

Compared with conventional design and construction techniques, the component-based design process demands a greater continuity and simultaneous planning across all stages of the project. From the design of the components and its joints, to the shaping of the envelope, to the fabrication of the panels and assembly on site, the entire process is controlled parametrically for increased accuracy and precision.

The result is a skin informed by Herman Miller’s philosophy that creates an identity inspired by their core body of work. The parametric surface modulates light and views into a flexible, open space. The plywood material forms a warm and casual ambience while its structure and assemblages expresses the dynamic process that combines technology with design.
