Introducing 55 William by Fortis

Anchored in legacy. Crafted for tomorrow.

A rare collection of only eight north-facing two-bedroom, three-bedroom and full-floor residences coming soon to William Street, Double Bay. Envisaged by renowned Sydney architects MHN Design Union (MHNDU), with interiors by internationally acclaimed 1508 London and landscape architecture by Wyer & Co., 55 William brings a refined new chapter to one of the harbour's most established neighbourhoods. Positioned just 200 metres from the water's edge and moments from Double Bay's lively village centre, it is an intimate address that balances tranquillity, connection and enduring quality.

Select residences are further elevated by views across the harbour, where water outlooks and glimpses of the city skyline create a constant connection to Sydney's ever-changing landscape and lend a sense of calm, light and openness to daily life. A communal rooftop terrace with sweeping harbour views provides an additional space for residents to relax, entertain and enjoy the beauty of the surrounding harbour setting.

Interiors are generously proportioned, light-filled and meticulously detailed, with expanded ceiling heights up to 3m high enhancing the sense of space, light and flow throughout. Carefully considered materials and bespoke finishes create an atmosphere of understated luxury, while open-plan living and dining areas are designed for both everyday comfort and effortless entertaining.

At the heart of each home, kitchens are crafted as elegant yet highly functional gathering spaces, appointed with natural stone, refined joinery and a suite of integrated Gaggenau appliances, including refrigeration, oven and cooktop. Feature pendant lighting above the island introduces warmth and character, complementing the rich material palette. Bathrooms continue the home's refined aesthetic, featuring premium fixtures and finishes throughout.

Living in Double Bay means enjoying one of Sydney’s most coveted village lifestyles. A short, level walk places cafés, restaurants, boutiques, ferry transport and everyday conveniences at your doorstep, while the harbour foreshore is only moments away. Defined by its walkability, sophistication and enduring appeal, Double Bay offers a lifestyle of effortless convenience in an exceptional waterfront setting.

55 William by Fortis is a boutique collection shaped by thoughtful design, craftsmanship and location, an intimate expression of contemporary harbour village living.
