Rammed Earth Homes

I've admired rammed earth homes for a long time, even though they're not really appropriate for the climate I live in. It's just that rammed earth walls are mesmerizing to look at. I get lost staring at the different layers of soil, in varying subtle shades of earth tone, flowing gracefully along along a wall. To my eye, rammed earth walls epitomize the very essence of natural beauty.

I can't think of any rammed earth builder that does it better than Terra Firma Builders Ltd. They have a way of crafting the most gracefully curved walls. Their designs blend with the surrounding landscape. Inside, massive earthen walls and sturdy timbers comfortably intertwine with delicate, artistic finishing. It's a totally unique aesthetic.

Terra Firma's website is fantastic. There's a wealth of images of their work in their portfolio. There's also a great explanation of why rammed earth is an effective, sustainable building solution.

Probably the most interesting thing I found on their site is that they use an unusual insulated rammed earth wall approach called SIREWALL (SIRE = Stabilized Insulated Rammed Earth). SIREWALL was developed by Meyer Krayenhoff, an environmental builder of over thirty years, who also founded Terra Firma. Here's an explanation from the SIREWALL site:

Stabilized, Insulated, Rammed Earth (SIRE) walls are made using rebar and insulation enveloped with the mass of 14 – 20 inches of rammed earth. This combination, along with SIREWALL®’s system for quality control and soil blending, builds walls that exceed current standards for energy efficiency and compressive strength. SIREWALL’s customizable forms refined over the last fifteen years by SIREWALL’s expert builders, work seamlessly with unique designs and modern finishes that have timeless appeal.

I always thought that would work. We've seen that concept applied to concrete walls, so why not rammed earth too? Actually, reading their FAQ, and noting that they're in Canada and do their building in British Columbia, I've learned that rammed earth can be a solution for climates other than hot, arid deserts, especially with the SIREWALL approach in place.

Note that Terra Firma builds complete homes only on their home turf. But they will build walls elsewhere, and let your builder finish the house. They also train and certify builders in the SIREWALL system, and offer design and consulting services. Wherever you are, whatever type of rammed earth project you might be considering, I think these would be the people to talk to.

I have new hope of living in a rammed earth house yet!
