How We Checked This Property
Rather than reproducing the listing as-is, we opened all ten listing images to confirm zero site photos, and disclose that — being new-build — the building dominates the assessed value.
What We Could Not Confirm
- The frontage field is blank. The drawing shows direct frontage on a ~6.0 m road, but the road's category should be confirmed with the listing agent.
- We recommend checking the 0.6–0.8 m earth retainer on the neighbouring boundary on site.
※ Rather than reproducing the listing as-is, we verified the figures against public sources such as the official road price maps and the listing photos. This is not based on a site visit, so please confirm on site and with the seller before deciding.

The listing's images are limited to a CG rendering, floor plans, a site plan and photographs of nearby facilities, with no photographs of the site itself, so retaining walls and the road frontage could not be checked. The road-access field is also blank. Please see the research notes below.
