light earth (’leichtlehm’)
the light earth technique was gradually developed over the last two decades in europe (primarily germany) to meet a growing demand for better insulation. in light earth building, loam is mixed with woodchips, pumice or other air pocket forming aggregates to create light, insulating walls within a structural wooden frame.
at a density between 350 and 1200 kg/cubicmetre, these walls are considerably lighter than the old mudbrick or rammed earth walls (2000-2200 kg/cubicmetre). as a result the
insulation (r-value) is up to ten times higher for the same wall thickness and new zealand building code requirements can easily be met.
external light earth walls are best complemented with the higher density of
rammed earth, used as thermal mass to store heat in interior walls and floors, but also built into a load-supporting wooden frame.
this saves reliance on non-compatible reinforcing materials like steel and cement, that consume a lot of energy in production and transport, and ensures
superior earthquake performance and full breathability.
the wooden frame also provides support for a
protective roof, a key factor in making the cement-free earth building process viable in new zealand weather conditions.
our homes combine refined contemporary architecture with traditional materials and craftsmanship of the highest quality. we set new standards in environmentally friendly building, and we are sure you will feel and appreciate the positive energy that is reflected by our work.
