Hornsby · Bushland Shire + Upper North Shore Heritage + Hawkesbury River
Builder Hornsby Sydney — Berowra, Wahroonga, Pennant Hills, Cherrybrook, Galston, Dural & Hornsby Shire
Buildana builds across the Hornsby Shire — from premium upper North Shore at Wahroonga, Normanhurst, Beecroft, Cheltenham, Pennant Hills, Cherrybrook and Westleigh, through Hornsby CBD adjacency at Hornsby, Asquith, Waitara and Thornleigh, bushland-fringe BAL at Hornsby Heights, Berowra, Berowra Heights, Mount Colah, Mount Kuring-gai and Cowan, Hawkesbury River foreshore at Brooklyn, Dangar Island and Berowra Waters, through to the premium acreage corridor at Galston, Dural, Glenorie, Arcadia, Berrilee, Fiddletown, Forest Glen, Maroota and Canoelands. Three conditions define the Shire: Hawkesbury sandstone bedrock (universal — drives saw-cut and rock-anchored slab engineering); BAL-29/40/FZ bushfire compliance (Ku-ring-gai Chase National Park, Berowra Valley, Marramarra and Dharug National Parks border the Shire); and a strict tree preservation order (canopy retention, AS4970 root-zone protection on every premium upper North Shore lot).
Bordered by Ku-ring-gai to the south, The Hills to the west, Hawkesbury River and Central Coast to the north, and Northern Beaches/Pittwater to the east (across Berowra Creek). Hornsby Shire Council governs under Hornsby LEP 2013 and Hornsby DCP 2013 — duplex 700m² minimum (higher than most LGAs), granny flats SEPP-compliant on most R2 lots, RU2/RU4 acreage with AWTS and BAL-29/40/FZ controls. Hornsby Hospital (~250 beds) and Hornsby Ku-ring-gai Hospital (combined facility under reconfiguration) anchor LGA employment. T1 North Shore line and T9 Northern line provide direct CBD access via Hornsby Junction (one of the busiest interchanges on Sydney Trains network). Hornsby CBD is one of the largest R4 mid-rise redevelopment precincts in the upper North Shore. Hawkesbury River foreshore and Brooklyn/Dangar Island/Berowra Waters water-frontage lots have foreshore building lines and unsewered AWTS requirements.
