hey mate i am a building supervisor in the project game it all depends on what you want to build ie two storey or single, how much you want to spend, time it takes to build, where you are building, etc. (no point building a home buyers house right on scarbough beach) if you no what i mean, all building companys have pros and cons we all have our problems it is how you fix those problems that really matters, but with work slowing it is not hard to get trades at the moment and good ones at that. do you have your own individual design or are you looking for a design that you like? the best way is try and ask people building with the companys you are thinking of building with, I know at the moment that mostly all building companys are throwing in some good extra's we are throwing in ducted air cons at the moment also, don't forget your small builders as they will surprise you how cheap they can be also you get that one on one effect with the builder, have you built before? If so who with?
