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.
