Custom Home in North Sydney — what it actually takes in 2026
Custom homes in North Sydney are premium harbourside builds — Federation mansions on Cremorne Point peninsulas, contemporary builds on Waverton and Wollstonecraft fall lots, sympathetic replacements behind retained heritage facades in Cammeray and Neutral Bay. Realistic premium custom cost runs $4,500–$6,500/m² for a 250–400m² high-spec build, with the upper end on harbour-fall lots in Kirribilli, Lavender Bay, McMahons Point, Cremorne Point, Kurraba Point and harbourside Waverton/Wollstonecraft where engineering, sandstone excavation and access constraints stack costs. Pre-construction 5–9 months for heritage and tree consents on protected streets. Engineered slabs, suspended slabs, substantial retaining and rock anchoring all standard on harbour-fall sites.
