Tiny House made of hemp | the house from the field, 2023
Dr. Norbert Höpfer, mineralogist, continues the working experience from Ruanda and Israel
For the 20th venue of ETF! a dismountable tiny house is created for reuse, approx. 2,20 x 4 m with an internal wooden frame, a dry stone wall facade made of hemp limestone, floor insulation with hemp lime and a pent roof with hemp wool insulation.
Rethinking the production of building materials – hemp shives bound with lime show the new way! Hemp lime is a mixture of the binder lime 1 part & 3-4 parts aggregate from hemp shives, the broken stalk of the plant.
Hemp lime has the following properties:
- regional & mobile manufacturing
- can be implemented directly with little effort
- carbon negativ (pro cbm minus 110-130 kg CO2)
- Hemp from natural fields (free of glyphosate)
- built-in moisture protection via the buffering effect of the binding agent
- suitable for grandchildren
- sand free
- cementless
- vegan
- transparent supply chain of raw materials
We use hemp hurds because:
- hemp is grown in Brandenburg & Mecklenburg
- in our case, the hemp comes from regional organic farming in Zempow
- hemp hurds occur en masse in the hemp plant
- hemp has an open-pored cell structure
- hemp has a positive effect on agriculture field economy
We use lime because:
- a lot of moisture is buffered (rapid absorption and release of moisture)
- of the disinfecting effect
- it is easy to repair (our bones are made of lime and therefore grow back together)
- lime is thinking ahead evolutionary
