Are there building envelopes to consider in regard to where exactly on the land your building can sit, some council also have requirements on this. Is there specific design requirements for that particular location, e.g. style of house, materials you can use, colours, design requirements, this list can be a very long one.
Anything from rock which will require a rock breaker to reactive soil that will need larger footings, the price can easily blow out and when building you will need to set aside funds for the inevitable, all of this cannot be determined until a soil sample is attained.

Services and easements
Check to see if you have all the services and how far away they are, if you cannot find them then you will need to contact your local service provider to see if they are available for your land and if not how much it will cost to get them installed or what alternatives you can use, e.g. Water, power, phone, gas, sewer, NBN. Also are there easements on the land as you will not be able to build over that easement and is that easement only to service your needs or everyone else’s.
