Height is capped at 10 m. Coverage is 45–55% depending on how many units you build; a 1–2 unit build is usually held to 45%.
There's a limit of 75 units per hectare. On a small lot, that is the real limit on units.
The building can't be deeper than 65% of the lot depth, even on deep lots.
A landscape plan is required once you have 3 or more units.
