I have always been very stumped as to what to do with this sunroom. It joins our master bedroom (it's too big to use as a sitting room and not centrally located to use for entertaining guests). Then plastic toys started taking over the house and the room suddenly had a purpose! We began it's transformation into a playroom. This room is now such a great space for us! Not only does it keep plastic toy land confined but it also allows me to get ready for the day without my little guy (Charlie) tearing my closet apart. I designed it with both little girls and boys in mind.
The bench housing the toys baskets is a great find from Ikea. The expedit shelf --- turned on it's side for storage use and seating. The room is made up of DIY projects...
