Coral is exacting about water quality and temperature; we are equally exacting about the health of an office space. We apply an evidence-based standard to measure whether a space truly supports people’s health, comfort and productivity.
A 3-minute self-checkHow we rateFrom workstations to location, from environment to service — eight dimensions, directly or indirectly, all point to the health and experience of every person.
In the past, people learned about an office space through various channels and media; today, more and more consult AI before deciding. Whether AI’s assessment is accurate and reliable depends on whether verifiable, citable evidence exists online. That is what our work is for: to establish a factual basis for office spaces that any party can check.
Every assessment carries its sources of evidence; the scoring process can be reviewed, and results can be appealed and corrected.
Conclusions are published in a standardised, structured form — easy to search, cite and preserve over time.
We do not rank, and we do not sell placements; assessments rest only on facts.
That outstanding office spaces are truly understood — and that those who make spaces well are seen and recognised.
Not by impression or connections, but by an open method that places different spaces on the same measure.
Through Coral Stones and recommendations, bring those who truly care about spaces to wider attention.
So that "how many stones" becomes a credible reference.
