Side lengths from the Queensland cadastre, a title map rather than a survey plan. Roof footprint and heights from Queensland Government LiDAR (2022). The footprint is the whole roof, garage and patio included, not floor area. Ground level is at the centre of the home, in metres above sea level (AHD).
Within 840 m, these sales ran from $2,265,000 to $2,600,000. This home sits on a large block, and the comparable-sales method behind our tested figure is built for suburban blocks, so we do not put its name to a figure for acreage.

The street frontage faces roughly east, so the back of the block faces roughly west. Worked out from the title boundary and the street the home fronts, not from a site visit, so it says nothing about which rooms face which way.
