About This Home

15 William Street #18-AB

UNIQUE FLEX LAYOUT | TRIPLE EXPOSURE | WATER VIEWS

Welcome home to an exceptional and highly versatile condominium opportunity at 15 William Street.

Units 18A (2BR/2BA) and 18B (Lofstyle) are being offered together, presenting a rare chance to create a custom 3BR/3BA residence spanning approximately 2,116 SF, or to enjoy the apartments individually for maximum flexibility.

The future owner may choose to combine both units into a seamless, expansive home tailored to their vision, or keep them separate—using the studio as a guest suite, home office, or income-producing rental to offset carrying costs. This layout offers a unique blend of lifestyle and investment value rarely found in the market.

With triple exposure and water views, both residences enjoy excellent natural light and an airy, open feel. The possibilities for customization and use are truly endless.

15 William Street is a full-service luxury condominium offering one of Downtown’s most comprehensive amenity packages. Residents enjoy over 30,000 SF of amenities, including a 50-foot indoor lap pool, a 15,000 SF fitness center with towel service, yoga studio, squash and basketball courts, screening room, dog park, children’s indoor and outdoor play areas, and a stunning rooftop lounge with sundeck. Additional conveniences include in-unit washer/dryer, parking in the building, 24-hour doorman and concierge, and a live-in resident manager.

A rare opportunity to design, invest, and live exactly the way you want.
