Out and about in South Beach.

I don’t understand the giant egg stuck between buildings (extras) but will try to find out for you.

PS
I now found out.
Officially known as "The Betsy Orb," it's an egg-shaped third-floor skybridge that links two hotels across a back alley. It solved a problem only evident to South Beach hoteliers: how to expand a pricey Ocean Drive hotel (The Betsy, built in 1941) by connecting it to a less pricey Collins Avenue hotel (The Carlton, built in 1937) without upsetting the clientele.
The architect, Allan Shulman, told the Miami Herald that, "A plain bridge seemed inadequate." So in 2016 he wrapped the passageway in rounded fiberglass panels made for radomes, the enclosures that protect spinning radar antennae. The result: The Egg. It's not only stylish, it also disguises its purpose to the paying customers; from the inside, it looks like just another hotel hallway.
