Having built with Burbank Homes I have to convey my absolute disappointment with their communication, services, ethical standards, quality of build, follow up after build is completed, asking for services to be provided (water & electric to within 6 mtrs of house site) and the charging you for a parallel service to be connected knowing (and using) the existing service.
My advise is to anyone thinking about building with Burbank Homes is don't. If you do get a good solicitor to check every piece of paperwork, make sure they put everything in writing & not verbally ask you for anything, get an independent building supervisor, get you own certifier to inspect every stage of the build. There are good builders out there I'm sure but Burbank Homes is not one of them.

UPDATE.

After hearing from Grace Nutter, State General Manager, Operations & Construction, the double up of charges on the services have now been credited & resolved. Due credit to Grace for looking into this case and not just brushing it off. Grace has also offered to speed up the 6 month warranty repairs in order to finalise all repairs not completed before handover.
