Located in Asheville, North Carolina, the 3,400 square foot Push House features a mainstream design with some very different systems behind its walls. The home’s use of hempcrete was only the start — for this application, hemp hurds are mixed with lime and water on-site and poured in-between the exterior supporting studs in lifts. It is the core to a breathable wall system — Hemcrete is actually less like concrete and more like infill straw bale, as it is non-structural. The insulating quality is r-2.5 per inch, and it has the unique ability to capture airborne pollutants over time — it absorbs carbon when it is grown and in place. The material’s high thermal mass helps keep a steady interior temperature as well.
Nation's First Hemp House Makes A Healthy Statement

Behind these groundbreaking walls is an idea -- we should be free to live in an environment that is non-toxic; one that helps clean rather than contaminate the air, the earth, and our bodies. That was the pivotal point of my conversation with design/builder Anthony Brenner on his house made from hemcrete based on industrial hemp-- the first in the US. The home has seen a meteoritic rise in the media, with coverage by CNN and USA Today, and even late night TV, but behind the headlines and punchlines shouting out about the latest and greatest green material is a home that fulfills the core concerns of an environmentally-sensitive habitat. With that lens his company Push Design was able to build a great home that is sizable but incredibly light on the environment, energy usage, and total cost.
