Again, a lot of these are leading-edge communities. These are prototypes. I agree, the first time you build something it's fairly common that you get those kinds of cost increases.
Just consider this. What if the new standard for building were this new way of doing things? It became a standard, you had efficiencies of scale, and all builders and contractors built according to those standards. The cost per unit would come down a lot. But I do agree. Those kinds of numbers do make sense in the initial runs.
