No crawl space. No. I do need to remove the cabinets as the wood floor goes under the cabinets. This is not your typical Home Depot bought wood flooring. This wood flooring is about 200 years old, very wide, very thick, and very hard. The cabinetry would need to be removed. Again, there is no crawl space. There is no concrete foundation. There is no sill as you are imagining it. There is no sill plate. There are massive, hand carved beams that act as structural support with some sort of stone foundation at the corners.
