Because the area designated as the suburb of Lansdowne is largely the undeveloped land previously owned by the Metropolitan Water Sewerage and Drainage Board, it consists almost entirely of parkland.

This included the creation of Lake Gillawarna, and other ponds full of aquatic life, native walks and pedestrian/cycle ways, playgrounds and barbecue and picnic facilities.

Lansdowne Bridge was built in 1834–35 from stone quarried on the banks of Georges River at what is now East Hills.
