One thing I really like about mixed-use, walkable neighborhoods is the collection of odd, little commercial buildings they support. While walking last weekend in Sunnyside, a north Denver neighborhood, I came across this small, freestanding 1,200 sf commercial building (c. 1954) that appears to have once served the neighborhood as a grocery. Today it houses an architect’s office. I like how readily these sort of commercial buildings are adaptable to modern uses even as neighborhoods change over time.
The ability to accommodate change allows these buildings to endure which from a sustainability perspective is great, but they also make neighborhoods more interesting too.
