21 William Street, Mermaid Beach

21 William Street delivers an intimate, low-rise collection of twelve boutique residences defined by expressive horizontal floorplates, generous cantilevers, and deep architectural setbacks. Thoughtfully orientated to capture northern light and coastal cross-ventilation across adjacent parkland, the building’s articulated form incorporates recessed façades and full-height glazing to elevate thermal comfort and visual privacy. Capped by an expansive private rooftop terrace, the structure marries robust coastal materials with refined spatial proportions designed for seamless subtropical living.
