I've decided to redesign the house for my property in Highland Park. This version is smaller (120 sm), and therefor will be less expensive to build. I am also planning on having the house built largely out of steel, and pre-fabricated by a company called Ecosteel based in Utah. The skin of the building is also a pre-fabricated assembly of R40 insulation sandwiched between sheets of metal, and simply screwed to the structural steel framing. The K-braces shown act as functional columns, supporting the cantilevered ends of the building. My estimated cost for the entire project is $250,000.
