Shortlisted: Luxury Residence - Asia Pacific Award

The International Design & Architecture Awards 2026

EY DESIGN

EY DESIGN has completed a luxury residential project in Chiba that reimagines a former quarry as an immersive hilltop retreat where architecture and interiors work together to deepen the connection to the surrounding landscape. Located around one hour from central Tokyo, the villa occupies an elevated site with sweeping views across Tokyo Bay and distant mountain ridgelines, offering a powerful sense of place shaped by the land itself.

From the outset, EY DESIGN developed a clear and consistent interior design narrative rooted in the site’s topography and industrial past, working in close dialogue with the architectural team, Katsuma Tai Architect & Associates (Tai and Associates).

The history of cutting and carving stone informed the interior concept, titled Memory of the Quarry, shaping material selections, spatial atmospheres and detailing throughout the interiors. Responding to the dynamic roof lines and ridgeline forms defined by the architecture, the same geometric rhythms and material language continue seamlessly inside, guiding choices in finishes, bespoke furniture, lighting and soft furnishings.

Set within a 3,159 square metre site and spanning 1,100 square metres, the estate comprises a Main House and an Annex linked by corridors and an elevated bridge. Circulation follows a continuous infinity shaped loop, creating a flowing sequence of interconnected spaces within the landscape. The Main House contains a living and dining kitchen overlooking an infinity pool, a spa with sauna, six bedrooms and entertainment areas. The Annex supports active engagement with nature through an outdoor kitchen and barbecue area, an indoor pool and a gym.

As a long standing client, the owner invited EY DESIGN to be involved from the earliest stages to ensure the interiors were fully integrated with the architecture. EY DESIGN refined spatial planning through detailed furniture layouts and circulation studies, and worked closely with architects, lighting designers and specialist consultants. EY DESIGN also oversaw kitchen design, bespoke joinery, all FF&E selection, art direction and final styling.

The result is a multisensory retreat where refined interiors and powerful architecture come together to create a deeply immersive and resolved living environment shaped by landscape, memory and movement.
