After many sleepless nights we have decided to go with Wisdom Homes for our new house. It not only came down to price (they were not the cheapest) but their inclusions were far superior.
One of the biggest deciding factors was the detail they went into for their tender in relation to what on site detention requirements we would need and were not trying to sugar coat the whole subject just to get the job. In the end we will need close to 50,000 litres of storage which will be in the vicinity of $50k. Wisdom were the only company to tell us this while others wrongly estimated $5k to $10k allowances.
We have now paid the next deposit for construction drawings and are glad we can finally move ahead.
