Making a range spawn for every player that joins?

I'm making a farm game, and I'd like to make it so that when a player joins, their "range" spawns somewhere in the game. Since all the players spawn in the lobby, there is going to be a teleport button that can teleport the player to their range when they press the button. I'm not asking/requesting anything as I know this is not a request site. I'm simply asking for some guidance. Thanks!
