144-148 Cowles Rd 0.28 Acres of Residential Land in Mosman, NSW 2088

Altura, positioned at 144–148 Cowles Road, presents a rare opportunity to acquire a premium development site in the heart of Mosman, one of Sydney’s most affluent suburbs. It offers an approved Floor Space Ratio (FSR) of 2.2:1 with significant potential to deliver a Gross Floor Area (GFA) of approximately 2,497 sqm, subject to amalgamation and council approval. This elevated corner site benefits from exceptional frontage on three sides, including rear lane access and a cul-de-sac, providing ease of design and construction flexibility. Its north/northeasterly aspect maximizes natural light and top-floor outlook, with sweeping views over Middle Harbour and the Sydney CBD skyline. With sloping topography suitable for basement integration, developers will find value in both efficiency and architectural creativity.
The property’s proximity to leading amenities further amplifies its appeal: only 391 meters to Mosman Village, about 1 km from Balmoral Beach, and offering convenient access to local schools, parks, and boutique retail precincts. This positioning, combined with the prestige of Mosman and outstanding lifestyle connectivity to the Sydney CBD, creates a compelling platform for a luxury multi-unit development.
