Looking for a Zombie Sandbox build type server...

I played on a server a while ago that was just basic sandbox gamemode but it was in a dark city map and it had lots of NPC zombies just roaming around and there wasnt any goals or rules or anything… noclip was obviously disabled and it had some aspects of RP servers like purchasing doors on the buildings and stuff and when you found an empty building you could claim the place and decorate it/ barricade it

just wondering if anyone knows of any servers like this? i would love to see a gamemode like this but add more aspects of survival like food scavenging and stuff…

Thanks
