Before we rent a stranger's apartment or buy an unfamiliar tool, we read the reviews. The listing tells us what a thing is; the people who used it tell us what it is like to live with. For the materials we build our homes from, we trust the first kind of knowledge and go without the second, because the people who live inside these walls rarely write any of it down.
Hempcrete has the sharpest version of this problem: a full spec sheet and almost no reviews. In a review of 309 studies, close to four-fifths measured the material's properties while under three percent touched what it is like to live in one. We know how hempcrete behaves in a wall section, and almost nothing about how it behaves in a life.
Habitat Atlas is the review layer for biomaterial buildings. I interview people who have lived in these homes for years, turn their testimony into evidence you can compare, and hold it on an open platform, so the homes already standing can speak for the ones not yet built.

This survey is the next round of that listening, and I would love your help with it. At the BBCM 2026 Summit I asked professionals to weigh which parts of a building’s story matter most to their own decisions.
This is the online version, open to anyone who shapes whether these buildings get built. Your ranking tells me which questions to put to the next group of occupants, and it feeds how Habitat Atlas decides what evidence to show each kind of decision-maker first.

Your role shapes how we read your answers, so start here.
