Hemp Building


Here you will learn how to build a house with hemp. Today hemp is being used to produce walls, ‘cement’, fiberboard, flooring, insulation, paneling, particleboard, plaster, plywood, reinforced concrete or hempcrete and roofing.

In Hemp Building the hardened material is resistant to rotting, rodents, insects and fire. It is many times lighter than cement and provides both thermal and sound insulation. Concrete pipes reinforced with hemp fiber cost less than one third the price of conventional polypropylene (a plastic/oil based material) reinforced concrete pipes and have greater flexibility and resistance to cracking. Fibreboard may also be used in Hemp Building, made from hemp it is not only light, but twice as strong and three times more elastic than fiberboard made from wood. Because of its superior strength and flexibility, it is resistant to cracking and breaking and therefore excellent for areas susceptible to hurricanes, tornadoes and earthquakes.

Hemp building products are not just another great idea for hemp, it is in fact one of the largest industries and uses for hemp fibre today. Environmentally friendly hemp building and sustainable house design that improves on straw bale or rammed earth. If you have an architect or designer looking at a strawbale, rammed earth or other supposedly eco building technique – we recommend hemp building for its cost, fire resistant properties, because it is termite and rodent proof and truly affordable housing.

There are a number of technologies used to create insulation, fibre boards and the fill of hemp monolithic buildings. You may view pictures of all these techniques at The Hemp Building Website.


If you are serious about building an affordable house with hemp, for retrofitting an extra room, improving a western or eastern wall, building a shed, or a 3 bed hemp house then we highly recommend the Build With Hemp Book where you will find a detailed construction manual (not about hemcrete or isochanvre – these are older techniques) with technical drawings, including the pros and cons of varying methods of hemp building. This guide is suitable for the serious amateur enthusiast and is actually used by professional hemp builders.
