My second suggestion is when a player buys a door with /buydoor, they are given the permission to build inside of the building they own. To set the area, an op would set the radius and link it to that door.

For example I would look at a door and type /setroom, or something like that. Then, I would do /setroom [x] [y] [z], and it would be linked to that door. Then, when a player buys that door, they can build in the room, like they're putting down props.

Method 2: I would look at a door and type /setroom. Then, I would select a cuboid with worldedit, and do /setroomw. Then it would link the cuboid I selected and link it with that door.

Thanks!
