Riversound Residence

The ground under it was tendered in 2011. Both ends of that are public; nobody puts them together.

What the land cost and what a unit sells for are not two ends of one sum. Between them sit construction over a multi-year build, financing, the development charge, marketing and agent commissions, GST, and the cost of holding unsold units. None of those is published for a named project, so this site does not estimate a developer’s cost or margin and no figure here should be read as one.

Those two are not the same square foot. Gross floor area includes what nobody buys — the corridors, the car park, the plant rooms — so the land rate is spread across more area than a unit is sold by. The ratio is arithmetic on two published figures and is not a return, a profit, or an appreciation.

Year by year, for a median-sized unit

90–100 sqm band. Counts in brackets; a year with fewer than 3 filed sales is kept and marked rather than dropped, because a reader can discount a thin year and cannot discount one that was silently removed.

The two ends of this page are not two ends of one sum. Between the tender and the first unit sold sit construction over a multi-year build, financing, the development charge, marketing and agent commissions, GST, and the cost of holding unsold stock. None of those is published for a named project, so nothing here estimates a developer’s cost or margin and no figure on this page should be read as one. Why that is refused.
