G’Day,

You need to get soil tests done as this will determine the class slab you may require, or if it has to be stumped or you may even need pilons. These can all add a substantial amount to the overall costs so i recommend you get one done.
the test can cost between $500-1000 roughly.

Also once you have a soil test you can then get proper plans drawn up. Having a guesstimated quote is no help as they may say $100k per unit but once soil test and proper construction plans are drawn it could blow out to $250k per unit.
good luck

there are pros and cons to both,
the bigger builders generally have soooo much happening they come across as being to busy to care and also rush through to get the job done as well as use anyone and everyone to build. However they do get it done quick (most of them). The smaller builders can take longer but due to them having to fight the big guys to get the job you generally get a better finish to the job (which is what we all want). They also would use much of the same trades therefore you know the finsh you will get and can see what you pay for. Also you will generally be able to deal with the owner of the company, unlike DEvine or Henley which is sometimes a good thing as it becomes more personal.

I deal with many different builders if you want some names of good honest builders i am more than happy to help

Good Luck
