A little small for more than one person, but it could still work…
This actually reminds me a lot of the first project I worked on when I moved to Tucson in 1980. It was a long, narrow lot that was zoned multi-family, and the architect I worked for had designed three separate townhouses for the property.
I always liked the layout of the units. Sadly I don't have the original plans any more, but once upon a time I did a "beach house" design based off the original layout, and surprisingly I do still have that:
I love this kind of stuff.
