Backroom lot ideas

I searched the forum but found no thread focusing on this. So, I think the idea of a split lot sounds good, attracting different sims and activities depending on the hour. I'm away from my game atm, but while I can't play there is nothing stopping me from planning.

Hoping you will share ideas and what you placed on the backroom lot!

Btw: is the daytime category restricted to library/museum? And is the night time category restricted to bar/lounge? Can we ie have a Vet in the day and a Discoteque during the night, or would it need to be basegame categories? Could it be a Lounge during day and a library in night?

Love to learn more!
