Georges Heights: houses beside Headland Park
Military headland turned parkland
Georges Heights is part of Mosman, postcode 2088, on the headland facing Middle Head. Work on the Georges Head Battery began in 1871, and a military hospital opened there in 1916 for First World War casualties. Today the Harbour Trust, a federal body, manages much of the area as a precinct of Headland Park, with artists, businesses, cafes and walking tracks reached from Middle Head Road.
Two planning systems
Land owned by the Harbour Trust is excluded from state planning law under its own Commonwealth Act, and federal environment and heritage law applies instead. The Trust leases out some former defence houses, such as those at Imperial Place and Commonwealth Avenue. Mosman's residential DCP also notes that certain land in Markham Close is governed by the Trust's management plan, which prevails if the two conflict.
Private house lots
Freehold homes in the surrounding residential streets, including along Middle Head Road, are assessed by Mosman Council under its LEP and residential DCP. The Trust's plans flag traffic and amenity on these residential edges as matters to manage carefully.

Common projects and how they get approved
What owners build here
For privately owned homes around Georges Heights, the work looks much like the rest of Mosman, with a few edge issues near the parkland. Typical Class 1 and 10 jobs are:
- Renovating or extending freehold houses near the headland, often with harbour outlooks.
- Pools and decks on steep blocks, with digging kept out of the minimum setbacks.
- Carports and garages set back past the house front, as council generally requires.
- Fences and retaining walls next to bushland or parkland edges, without barbed wire.
Trust owned buildings and leased former defence houses follow the Trust's own approval process instead.
How approval usually works
Start by confirming who owns the land and which planning system applies. A planning certificate from Mosman Council will show a freehold lot's zoning and any heritage status. For a Markham Close lot, read the Trust's management plan alongside the DCP. Where Mosman rules apply, a CDC (a fast-track approval under state rules) may be possible for simpler work, while larger additions often need a DA because of views, bushfire mapping or heritage. Lots near bushland may face extra setbacks if they are bushfire prone. CertifiBuild works on NSW homes and Class 10 structures, checks the land status and maps at the start, and keeps communication clear through each stage.

Local questions
Questions we hear about this suburb.
No two lots in Georges Heights are the same. Give us your address and we will check every map that affects it.
See the council pageDoes Mosman Council approve work on Harbour Trust houses?
Generally, no. Land owned by the Harbour Trust is excluded from NSW planning law, so changes to Trust buildings, including the leased former defence houses at Imperial Place and Commonwealth Avenue, go through the Trust’s own process and federal requirements. Freehold homes on ordinary Mosman land, such as those along Middle Head Road, are assessed by Mosman Council under its local plan and residential development control plan (DCP). That is where a private certifier can help. Confirm who owns your land before planning any work.
My home is in Markham Close. Which rules apply?
Both Mosman’s residential development control plan (DCP) and the Harbour Trust management plan. The DCP notes that certain land in Markham Close is subject to the Trust’s plan, and where the two differ, the Trust’s plan prevails. Order a planning certificate from Mosman Council to confirm the zoning and any heritage notation, then read the two documents side by side. Do this before a swimming pool, deck or extension is designed, so the layout reflects whichever rule is stricter on your site.
Do bushfire rules apply near the headland bushland?
They can. Mosman has significant bushland edges where homes meet Harbour Trust and national park land around the headland. If the bushfire map shows your Georges Heights lot as bushfire prone, the development control plan (DCP) notes that extra setbacks may apply, and new work must meet bushfire construction standards. That can also push larger jobs toward a development application (DA). Check the map early, and if the lot is flagged, arrange a bushfire assessment before design. Fences on these edges should avoid barbed wire.
