William and I have been hashing out the details of construction for the coming year. Our plan is at this wiki page and further details on techniques to be used are here. We are currently planning on a CEB-straw bale hybrid – a double CEB brick wall with straw bale inside. We expect the R-value to be at least 40 – making it a super-insulated house. Add the solar space in front, and we would not need a pile of firewood for winter, as shown in the following video. The video shows the location for this construction – close to the water well so we can have year-round water without doing too much trenching for water pipe.
Noteworthy features are CEB floor, masonry stove, living roof, rainwater catchment, greenhouse in front, open source air-powered water pump, our own lumber, CEB water cistern, and keyhole growing space right in front. This means that in May, we will build LifeTrac II, PowerCube II, and the dimensional sawmill. In June and July, we’ll test the toolchain – cut lumber, test stabilized and lime bricks, do the well pump and prepare water lines, do site preparation, build trusses from our lumber, prepare brick rollers, test slurry mixes, and other details. If we’re on top of it, we’ll begin the wall-raising on August 1st, and hold a CEB hybrid construction workshop.
In the meantime, we invite open architecture collaboration – coming up with technical drawings and models, as well as working out the details on all the other house subsystems.
