Castlecrag is a quiet, leafy pocket of the Lower North Shore, planned by Walter Burley Griffin around the bushland ridges above Middle Harbour. You'll find his original stone-and-render homes along The Scarp, Edinburgh Rd and The Bulwark, sitting next to modern architect-designed rebuilds on steep bushland blocks. Many homes back onto reserves and the harbour foreshore, and the local shops on Edinburgh Rd anchor the village. The mix of heritage Griffin houses and high-end new builds means no two jobs here look the same.
Castlecrag's housing keeps our residential team busy with detailed, design-led work. Older Griffin-era homes often need switchboard upgrades, full rewires and safety-switch installs once owners start renovating. The newer rebuilds bring large lighting plans, three-phase supply, EV chargers in carports and garages, and pool, garden and foreshore lighting that has to stand up to a damp bushland setting. As a Level 2 ASP, we can also upgrade service mains and metering when a renovation or rebuild pushes the supply beyond the old connection.
