Here are my recommendations:

C1toDS is a pretty big metaroom but don't let that fool you. If you're going to fit 20+ norns in there, they will almost all be in the kitchen by the fridge and if they're not there, they probably got too crowded and ran through the garden which also has ample food sources.

If you don't mind working with garden box and other ecosystem add-ons, rooms such as Veridia, Freedom Project, Biodome or other Tabula Rasa (empty) metarooms then those can be made to suit the needs of over thirty norns.

Terra Nornia, KT and the Hydroponics bay are if you are more daring and prefer active play instead of just wolfling runs.

If you don't mind the cold, & setting up food sources & maybe heat sources, Chione has plenty of room for 20+ creatures. Once I got the food sources set up the way I like, I've been running all of my recent wolfling runs in Chione. And my wolfling runs usually number more than 40+ creatures.
