  • One 24 foot wall is constructed using 11” thick hempcrete Z Panels. This acts as a thermal storage or Trombe  Thermal storage walls align with passive house design principles. Thermal mass within a building is beneficial as it acts as a heat sink.  With an R-value of more than 20, and a mass of 3K pounds, The Z Panel wall will heat up and cool down slowly,  (called thermal inertia) helping regulate indoor air temperature.  Constructing the thermal mass wall out of hempcrete Z Panels is uniquely beneficial since Z Panels are mold, fire, rot, and pest resistant.  Hempcrete also helps regulate the humidity levels, and as a bonus, is a carbon- negative material! You can see the wall installation here.

Design Principles:

  • No-VOC: We specifically chose materials that had either no or minimal VOC’s or any substance that might be detrimental to those with chemical sensitivities.  This meant that almost everything had to be purchased unfinished, and then finished by us before installation.  This is labor-intensive, but we were committed to ensuring each, and every finish was non-toxic.
  • Strong and Safe: Hempcrete is a unique and strong material, in addition being non-toxic and fire-resistant.  Its properties are unparalleled when it comes to building materials. A steel exterior ensures that this home will be not only very durable in every kind of weather, but also fire-resistant.
  • Functional: Your home should be low maintenance and work well for you. It should be practical and have a low ongoing operational cost.  It is for this reason you won’t see any gas appliances.  If you have access to water and electricity, you have everything you need for this tiny home. No need to refill propane tanks.  This is optimal for those who may have solar capabilities.
  • Beautiful: When we say “no compromises” that means that we believe a home can be incredibly functional, safe, structurally sound, and of course beautiful. We want the first thing people to say when they see your home to be “that is beautiful.”  Sustainable, safe, and non-toxic homes don’t have to look unusual.  They can and should be beautiful.
  • Sustainable: We take seriously being good stewards of the earth, and empowering people to maximize self-sufficiency through sustainable systems and materials.
