In Baltimore and Philadelphia it’s about the row house. In NYC the brownstones, Charleston is about the porch.
Since the 1700’s it has been the place to get a breeze, escape the heat. In many buildings the porch is on the side of a house, in an alley.
Some buildings you enter on the side of a house, on a porch. Really based on the off shore breeze and the street you live on.
Traditionally the wealthy left town during the summer and went inland to the pine woods. The air was better and misquetoes far less. Charleston was always surrounded by swamps. It’s where they rice grew…and the money.
Little fact here;
Charleston is the second city here. The first was across the river and called Charles Towne. The first town was founded in 1663.
It seems the settlers sailed into the harbor, got off the boat, and set up a town. Just like that with no real plan on where to build.
Being hearty British stock the town grew to 800 before they realized living in a swamp was a really bad idea. They moved over to the ocean shore with a breeze.
Of course some time later the discovered hurricanes, but that’s a story for another time.
