I think that you havn't understood.

Admin create house, when house goes create the interior id is 12.
When player buy a house the house is the interior id 12 but if he press space, he can buy other interior with dialog list interiors. when he choise case 0 (for exemple) i want that the interior change for the interior that i set. Obviusly i set the x y z of the exit of the new interior setted so the player when type /join spawn in coords.
