Fortis continues eastern suburbs push with 55 William launch
Joel RobinsonAug 20, 2026PROJECT LAUNCH

Fortis is continuing its stronghold on Sydn​ey’s eastern suburbs apartment market, launching in September its latest boutique Double Bay development, 55 William.

55 William presents just eight north-facing two-bedroom, three-bedroom and full-floor residences to the market, priced from $4.5 million.

The upcoming launch comes just weeks after Fortis secured approval for the $80 million development, its third eastern suburbs approval in two months. Construction is already underway, with completion targeted for 2028.

55 William adds to a growing concentration of Fortis projects in and around Double Bay, a market the developer has become increasingly active in over recent years.

Fortis previously completed the nine-residence Marmont on New South Head Road, while it is currently developing a mixed-use residential and retail project at 12 Cross Street. Its wider Double Bay footprint also extends into commercial and retail development.

The developer's broader Sydney residential pipeline is particularly concentrated across the eastern suburbs, with projects spanning Doub​le Bay, Ro​se Bay, Wo​ollahra, Dar​ling Point, Poi​nt Piper and Eli​zabeth Bay.

At 55 William, Fortis has again turned to MHN Design Union, the architecture practice behind several of its eastern suburbs projects, while London-based 1508 London has been appointed to handle the interiors and Wyer & Co the landscaping.

The six-level building will comprise a combination of two and three-bedroom apartments, including a garden residence, full-floor apartments, a sub-penthouse and penthouse. Each residence will have secure basement parking and private outdoor space.

A rooftop terrace for all residents, along with select apartments, enjoys views across Double Bay Harbour and toward the Sydney skyline.

Ceiling heights will reach up to three metres in select residences, while the kitchens will feature natural stone and integrated Gaggenau appliances.

 

 

The boutique nature of the project reflects the type of stock Fortis has increasingly targeted across Sydney's eastern suburbs, where larger apartments and smaller buildings are being pitched primarily toward local owner-occupiers and downsizers.

Fortis Group General Manager Ed Eve said the developer continues to see demand from buyers wanting to remain in the eastern suburbs but move into newer, lower-maintenance housing.

“We're seeing continued demand from local owner-occupiers and downsizers looking for high-quality homes that allow them to remain in the eastern suburbs, close to the lifestyle and community they know,” Eve said.

55 William is also one of the early projects to respond directly to the NSW Government's Low and Mid-Rise Housing reforms. Fortis had previously secured approval for just two townhouses on the 599 sqm site before revising the scheme to eight apartments following the planning changes.

Situated one street back from Double Bay's water's edge, the project enjoys an enviable harbourside setting within walking distance of Double Bay Village and the ferry wharf.

Fortis has increasingly made the eastern suburbs a major focus of its Sydney pipeline. Beyond Double Bay, it recently completed the 14-residence Piper in Point Piper and has projects underway or planned across Rose Bay, Woollahra and Darling Point.

The developer recently secured approval for Verano in Rose Bay, a six-level development comprising 21 two, three and four-bedroom apartments, also designed by MHNDU.

55 William is soon to be release to the market with VIP appointments commencing early September, with residences priced from $4.5 million.
