Castlecrag suburb profile
Castlecrag is a quiet harbourside suburb on Sydney's lower North Shore with a distinctive garden suburb pedigree from Walter Burley Griffin and Marion Mahony Griffin. Curving streets wind around sandstone outcrops and pockets of native bush, and homes sit low in the landscape, from Griffins-designed cottages and interwar masonry houses to discreet contemporary builds that respect the foreshore. The suburb has a small village centre with cafes and local shops, easy access to waterfront reserves and walking tracks, and a peaceful community atmosphere that appeals to families, professionals and retirees who want a relaxed harbour-edge lifestyle while still close to the city.
