To judge by its dimensions — 45 feet by 6 feet 6 inches — the structure at 128 Day Avenue in Toronto has more in common with a bowling alley than with a residence. And in fact, the site it occupies was originally meant to be an alley. But in 1912 an enterprising local builder named Arthur Weeden, noting that the city hadn't cut the curb to allow vehicles to pass, decided to shoehorn a small house onto the narrow lot.
For more than 25 years, Weeden himself lived there, first with his wife and then — after her death — alone. The property changed hands several times over the following half-century; the current owner, David Blois, remodeled it extensively before putting it on the market last fall for $179,900. As of this writing it's still available — the perfect place, as real estate people like to say, for the right person.
