Sweetness...
I spoke with Ben the Builder and he said it should be possible to get the extension of the back porch like we are requesting. He said they could do it when they pour the driveway. He estimates it will be $5-6 per sq ft, so that should be something we can cover in cash. Since we wanted it to be flush with the existing patio, it may run a bit more since I'm assuming they have to make it thicker, but it should still be feasible. Ben estimated they would have the lumber delivery early this week and our house might starting taking (more) shape by Wednesday. Updates forthcoming.
