I’ve noticed that too. The odd count usually comes down to symmetry—one window in the center and an even number of windows on either side. It’s a simple way to keep a façade balanced without a true midpoint. Some old builders also liked the visual rhythm that odd numbers give, and a single central window often served as a focal point for a fireplace or stairwell. I haven’t found a formal study, but architectural handbooks from the 18th and 19th centuries repeatedly recommend odd arrangements for that very reason. It’s more about design logic than a hidden algorithm.

Odd windows give that clean symmetry, even ones do feel… off, like a broken rhythm. I’ve already filed the data, so you can hand it over and walk away if that’s your style.

Got it. File noted. Good luck.
