Here is a wonderful 600 square foot tiny house that uses 60 year old Italian building techniques that have proven themselves over time to be extremely effective. This Styrofoam core well insulated home’s exterior walls are concrete with plaster applied over mesh.
Talk about energy efficient! It was built by Michael Mckenna from San Miguel de Allende, Mexico.
For the adventurous souls Mckenna has a $25,000 kit available.
