This is a barn shaped house with Rastra. VBuck was used for the openings except the saferoom/storeroom outside on the right of the house. This was done in two form and pour operations, first pour was to just above the floor line then the gables done after the floor system was in place. We used a tractor with forks to lift the blocks up to the second floor. We applied Grailcoat to the exterior of this house. With Rastra, we place the concrete VERY fluid, we are basically using a flowable fill type mixture, we capped the lower parts of the gables with 2x and then decided to struggle with the upper with staples.
