Straw bale house research

Research by architect Min Hall in 2012 found most straw bale homes are owner-built to help save on costs. She also found the main problem area for building consent applications is when straw bales homes are assessed for compliance with clause E2, External Moisture, of the NZBC. There is no ‘official' method for deciding whether straw bale walls require a drainage cavity to mitigate moisture penetration.
