what looks like it could be the main entrance looks like it is outfitted with a doctors office type waiting room window. certainly could be that someone was thinking of an assisted living or rehab thing.
one thought, seeing the brick wall through the studs looks like it was built on the cheap. most all of the construction i see has plywood, chip board and/or insulating sheets secured over the framing before masonry work begins. that doesn't look right.
the smaller building looks like it is finished out like a residence. nice pool, too.
