I live in Australia.Sydney's South.Hurstville area.What size land would I need to have a contractor build 4x2

Question

4 x 2 bedroom units....And if I wanted to build 6x2 bedroom units, what land size would be enough to build either a 4x2 and 6x2 bedroom unit project. With garages or car spaces included.

Could you give me the two figures?

Answer 1

figures I'm not too sure of, however the best thing to do is to look for a site of 2 old  houses side by side and this should be ideal. Even better if it is a deep block, as you will have the room.
