We need a place for more people to live in. I've got a full guest house with each of my girls pregnant and nowhere for the adult kids to live unless i cheat and add extra rooms to the guest house.
How about bunk housing, so 10 people to each house, example, or homes outside the settlement, close to farming area but unless theres guards then they can get attacked. Guards lessen the attack for the farming area and the outside homes.
