i have made a "holdincell" but it wont allow me to make it a room??? why? i have all the toilets and benches placed am i sopsosed to use a fondation only? or just brick walls?
Ok, first, use a foundation to build a building that the holding cell will be in.
Next, zone the area you want the holding cell to be as a holding cell. The holding cell zone has to be 5 by 5.
Then put a bench and toilet in the holding cell, then wait for your workers to put it in.
