Second-Storey & Rear Additions in Manly Vale
A home extension in Manly Vale buys Manly-fringe lifestyle without the beachfront price. This inland suburb sits a short hop from Manly proper, and its Federation cottages, inter-war homes and post-war brick on 450 to 700m² blocks have the block depth the beachfront stock lacks. At a $2.4M to $3.6M median, extending here beats trading up the hill by a margin that funds the build.
The era mix decides the method. Inter-war brick takes a first-floor addition on its walls, post-war stock extends better at ground level or wants steel to go up. Hawkesbury Sandstone means rock excavation of $40K to $100K on many lots, so we test before pricing. Heritage Conservation Areas over the older streets watch the frontages, and R3 zoning along Condamine Street adds options on the right block near Manly Dam Reserve.
What I would check first on your Manly Vale house: the era of the walls, the sandstone under a dig, and any heritage pocket. Those three set the method and the spend.
