Case Study: Financing and Insuring a Hempcrete Home

The Natural Building Alliance (NaBA) launched its 2026 Webinar Series June 23, 2026 with a case study on financing and insuring a natural build.

In an interview with carpenter and DIY general contractor Keith Bien, participants learned how the Biens (Keith and Kate) built their 3,000-square-foot, non-traditional home in Georgia using HempBLOCK International’s BioSYS mortarless hemp blocks.

Keith Bien details his strategy for acquiring a construction loan from a regional bank that then converts into a mortgage loan. He also discusses the types of insurance required, including construction site insurance and then standard homeowner insurance. 

Bien gave tips on strategies including clear documentation of the project and using industry-standard terminology. 

The session also covered structural engineering, utility installation, and liability management for onsite workshops. The full recording is available on the Natural Building Alliance YouTube channel.
