Masonry Stove
Used blown on cement stucco (exterior)—believes it works better than troweled on, for strawbale, because the stucco binds more securely and deeper into the straw.
House is warm and comfortable.
He felt he should have backed 12x12 beams with tar paper because they move as their moisture varies and slightly twisted out of the interior plaster.
*Does not count owner labor. Cost estimated at $250Ft2, if done by contractors.
A meticulously crafted two story timber frame/strawbale (infill) house. The straw bales were installed on the exterior of the load bearing timber frame. The bales are 23" wide (somewhat wider than usual) for added insulation. The thick walls of straw bale have given the doors and windows a rich and elegant look. The homeowner had no problem getting home insurance with this straw bale house. The owner almost exclusively used salvaged/recycled wood, antique plumbing fixtures, and lights that he collected over many years. He used 80 year old beams from the warehouse of an Omak mill, and found recycled flooring at Havilla Shake in Tonasket. Using salvaged/recycled wood was probably more expensive than buying new material, but the owner wanted a "period look" (posts and beams were not remilled), and it kept new wood from being cut; this is an especially important consideration when dealing with large timbers because they are usually cut from old growth trees.
Cement stucco was used on the exterior. The stucco was blown on, a method that the owner believes gives better adhesion and deeper penetration of the stucco to the straw than troweling. He used stucco wire rather than metal lathe, on the wall. The interior and exterior walls are exceptionally smooth.
A masonry stove (aka: "Russian fireplace") is the primary heating source. It also contains a small oven for cooking, which is used often. The stove has copper pipes running through the masonry to preheat water. The house has electric radiant heat embedded in a 3" thick cement floor as back-up heating, but is rarely used. The house has a crawl space and the cement floor was poured on plywood, but the joists are 12" OC to support the weight.

The exterior landscaping has recycled colored concrete pavers that the owner made. These colors add a soft Mediterranean feel, and allow for water to flow through to the earth below.

Owner's Advice: Remember to detail for airtightness around the straw bales.
