Free site topo

See how the block falls before anything is drawn

Type in a NSW address. In about a minute you get an A3 topo plan — contours, spot levels, the fall across the lot and a slope map over an aerial photo — and a CAD file your designer can open. Free, emailed to you, no call needed.

The levels decide more than people expect: whether a slab works or the floor has to be suspended, how much retaining there is, where the stormwater goes and how steep the driveway gets. Knowing that before a design starts is cheaper than finding out after.
