Here's another view of Homer's side of the house. As you can see, they're getting ready to pour the 40-foot RV slab and the driveway that connects it to the street. You can also see the RV sewer drain sticking up as an extension of the PVC pipe that will be cut off at slab level after the concrete is poured.
People continue to assume this is a two-story house, but it definitely isn't! Lots of tall ceilings inside, though, will make the small house seem spacious.
