Houses way/plugin

Hey, i am looking for a way or plugin to buy and sell houses without an actual economy plugin. I was wondering if this is possible. I am not a huge fan of economy plugins so i use emeralds and gold etc to buy or trade stuff in my server. It doesn’t have to be a plugin maybe there is a way to do this like you have a house u want to buy and there is a chest infront of the house and the player put like 30 emeralds in the chest to buy the house. Also the player can only switch in the house but not remove or place blocks in the house since i don’t want any griefed looking houses :/. The players don’t have to pay over and over again it will be fine if they pay the house just one time. It would be nice if it lookeda bit like the houses plugin from bukkit but for that one u need economy plugins. Anyone know if there is a way or plugin to do this?
Thanx :slight_smile:
