In-between Architects creates a simplex of two adjoining units in two distinctive tones for a four-generation family from the age of 12 to 90 in Mount Regalia Kau To Shan, a serene and undisturbed location up in the layers of mountains.  Different needs have been taken care for the family members at different age. The grandparents request a spacious living space with maximum daylight and storage, also with a comfortable dining space for family dinner and gathering whilst the son's family seek a cool and minimal living style that allows greeting guests with ambience and evoking visual zones alongside the beautiful wine and cuisine.

In the son’s family’s, the spaces are characterised by monochrome and a range of bold materials like artistic wall paint, rusticated stone wall and textured wood flooring. The right amount of luminosity is essential to highlight owner's art pieces and to create different moods for happenings from film-screening to wine tasting. A built-in fireplace sits in a low positioned linear metal shelving that runs along from dining to living space.

All the cabinets and wardrobe are built by Alublu, who specialises in aluminum system furniture and wall panelling system using state-of-art materials such as compact laminate on walls, concealed doors and corridors. This collaboration is formed since the very beginning from layout planning stage. With the system design of flexibility, configuration changes can be made easily on the wall system to suit the family's future needs.
