Cost of building construction, excluding design fees, site preparation, and unconditioned space was $188,731. The square footage of the conditioned space, measured from the exterior is 3,072 square feet. This includes the conditioned basement but not the garage. The cost per square foot, including the PV system was $61.44. This project was built on speculation. In the summer of 2011 we began construction on the first two homes. The first home was sold by October. By the following October in 2012 all of the homes were either sold or under agreement. We had planned on a 3.5 year build out. Cost includes PV system.
