Love this play area over the bed, like the anti-loft bed. I think I& leave off the first couple of steps of the ladder and make it a safer place for the older kids to play with and store their LEGO creations. (Apartment Therapy with loft bed inspiration)
Not sure what I think about using lighting in side the cabinets in the craft room. Maybe glass front cabinets on top of it? I tend to put small lamps into book shelves. So we are going to need outlets in the bookshelves. Any bookshelves in the house.
Rows of matching Billy bookcases from Ikea work well here. Consider that the books and accessories offer the pop while the bookcases provide the background. (contemporary living room by Smith & Vansant Architects PC)
