This house must have been one of the first on its block. It was built in 1920 (but there was at least one house built nearby in 1918), and it ended up being situated on an ample 66 foot lot. The lot is now divided, with two houses under construction. The photos show 3524 West 21st Avenue in mid May 2013; it was torn down in early July.
Just to the east is one of the few "narrow" houses in the Dunbar area, this one built in 1988 on a 16.5 foot lot. They were not quite as controversial in their day as laneway houses are today, but people wondered at the time, why would anyone want to live in a small house?
