Bellevue Hill, Sydney
Bellevue Hill, Sydney
Located in Sydney’s harbourside suburb of Bellevue Hill, this multi-generational residence unites two former dwellings into a singular home of calm and cohesion. The design addresses the site’s complexity and the evolving needs of its occupants, offering a tranquil retreat with expansive views over the harbour, city skyline and Rose Bay.

A refined composition of rendered blade walls, white steel screening and horizontal banding redefines the home’s identity, softening its presentation and enhancing privacy. The façade replaces a previously fragmented expression with a unified, residential language of quiet strength.

Outdoor spaces are integrated across the levels—from inward-facing courtyards to a rooftop lounge, lap pool and terrace—each engaging with light, aspect and landscape. A Japanese-inspired garden provides a moment of stillness, framed by sculptural forms that balance openness and enclosure.

Internally, the home is restructured into generous, multi-purpose living zones that support daily life and accommodate guests. A self-contained studio supplements the upper-level bedrooms, while a central timber stair connects the four levels. Intimate sitting areas offer retreat without compromising connection.

Materials are timeless and restrained—white terrazzo, plaster, linen and oak—punctuated by dark granite, stainless steel and bespoke timber elements. Bathrooms combine micro-cement walls with handcrafted vanities and bathtubs, adding warmth and depth.

Furniture and objects are curated to reflect the family’s sensibility, reinforcing a sense of continuity throughout. Bellevue Hill House is an expression of quiet luxury—an architecture defined by light, proportion and texture, designed for longevity and ease.
