Why Do Some Windows Have a “Potbelly”?
This style might be referred to as a “potbelly grille” or “window belly bars.” Some Reddit users thought that the bulge was for placing flower boxes. You can’t place a flower box on the rounded bars themselves, but you could extend one out from the windowsill.
Other Redditors argued that the bulges serve a a security purpose, since they’re often found only on the ground floor of buildings. New Yorkers argued that the bulge was for AC units!
Where Can I Find Window Bars Like This?
You can often find them in Mediterranean and Latin countries. In the United States, look for them when you’re walking down the street in New York. Window grilles have a long history of being used in urban areas for security—and they double as ornamental ironwork. Certain cities, like New York, still have city codes requiring bars to be installed if a child under 10 lives in the residence. Whether the bars are straight or curved may depend on the builder.
If you ever move into an apartment with a “potbelly” in the window grille, you’ll know how to use it!
