Several staff were on hand to help Shafraaz with pouring of the upper floor concrete topping for his house! The concrete topping is to provide a heavy thermal mass for this passive solar house. Little did Shafraaz know he had such an experienced and brilliant crew!  Thanks to Jud, Rita, Mike J., Robert & Matt for sharing their experience and Saturday!
