This research investigates the environmental and health implications of material selection within the "van

life" community, focusing on the hidden hazards of common construction materials. The study addresses a

central question: How can conversion builders effectively navigate sustainable choices regarding the

materials, products, and functions of their custom vans?

The study employed qualitative and quantitative approaches, including three interviews and seven surveys

with active community members. Findings indicate a significant interest in sustainability; however, adoption

is hindered by budgetary constraints and a lack of accessible information regarding material toxicity and

environmental impact. The research highlights a critical over-reliance on manufacturer labels, which

frequently lack transparency concerning sourcing and health exposure risks. Additionally, a gap in

consumer literacy regarding "greenwashing" practices and third-party certifications often leads builders to

inadvertently support non-sustainable manufacturing.

To address these barriers, this project proposes a design-led educational framework. By providing the van

life community with evidence-based, relatable material education, this initiative aims to foster sustainable

behavior change, clarify complex sourcing data, and empower builders to make confident, eco-conscious

decisions.
