Shutters, doors, windows, and bricks, Dutch style. Many buildings like this don’t have elevators and the stairways are very narrow. So, moving furniture, appliances and other large items has to happen through these large window/door openings. On a lot of buildings above the uppermost of these windows, there’s a post-and-hook kind of contraption that is used for affixing a pulley system for hoisting big stuff. An interesting solution that creates a rather unique architectural feature on these old-school homes.
