The part you rapped is a temporary cladding facing the loading dock of an adjacent building on the east side. I assume the concern was garbage trucks would chip actual stone.
I've always hated inside balconies because I find them a touch claustrophobic but these are kinda fun. I could see myself on one of those, enjoying my morning cup of tea.
Speaking of said avatar, I recently noticed that 1 St Thomas is a little like the Avenue Rd Four Seasons in Deco-Classical drag--similar height, similar whiteness, similar polygonal bays and balconies...
Ok, so if 1 St. Thomas is modern brutalism in drag. hmmm. Then, maaaybe modernism is just deco in a big box. With no bow.
To everyone who knocked on it, I salute you. I guess the cladding is a titch thicker than I originally thought. But still not solid, like brick or stone. Which was a surprise to me. Guess I need to out more. And knock on things.
