So cute! And you can use the greenhouse separate from the stand if you'd like (and that shelf in the bottom of the stand can be slid up or down to where you like it).
The greenhouse portion is 3-1/2" tall (and the little "room" portion is 2-3/4" x 2"). I love the wonky little roof with the little round windows on the sides.
The roof just lifts off to access the inside (or you can glue it all together when you've finished decorating).
