The middle and the middle half of the costs declared to Blacktown City Council for Granny flat projects lodged over the last 12 months, from the public register. A declared cost is not a contract price.

The drawing covers the middle of the spread, not the extremes: one outlier would flatten the box into a line.

1 lodgements were too small to be a whole project of this kind and were left out of the band.

This is not a contract price

A declared cost of works is the applicant’s own estimate, filed so the council can work out a lodgement fee. It is not a contract price. Under the official definition it covers design and construction and excludes GST and the land.
