What's was that Map!? Plz Help!

So basically I quit gmod for a year. Now I want my mods back and sucessfully got most but the one thing I don’t have is the one thing I liked the most. If you could help thx.

What is this map?
-Enterable Houses
-Destroyed Playground with one of those wheel things you stand on and swings
-No zombies at default
-Like rattling background sounds

I know that’s kinda useless info but if someone had an idea plz post thanks.
