"Granny flats" or backyard suites can provide all the charm of an East Coast house, with much less cost and maintenance - should be legalized in zoning code. These could also function as high-end vacation rentals.
I like that some of these uppers have divided glass. I also like the small appliance garage. Handy for toaster, juicer and mixer. I either want that on countertop somewhere on easy to reach storage in the island.
