Glad you like the kitchen wall. However it is not stone. The entire wall along with many other interior and exterior walls are solid and structural "Board Formed Concrete" walls. They are a key design element throughout the property enhancing not only the buildings but the landscape as well.

what material is the flooring?

The floors are poured in place sections of natural (no color added) concrete. We did a series of grinding/polish work that exposed the aggregate. It looks very "terrazzo like" in many locations. It brought out all the natural stone/ pebble colors that compliment the colors used in our kitchen materials.

What material is the kitchen hood?

It's steel. Powder coat matched Henrybuilt's color. It was fabricated on site. Hood insert framed out and wrapped in plywood. Fitted with steel.
