On the wall opposite the media cabinet, custom cubby benches store bins of toys. A chalkboard table for playing doubles as a storage spot for larger bins of toys. this is a nice play area for kids. it has nice storage too:)
DIY Storage bench - great idea if you have a kitchen under first window. Add cushion, use bench as seating. Put bench against wall, push table against wall, great storage for occasionally used kitchen things.
Possible option for "framing" the window seat in the play area with functional storage, would also add pillows to bench area since window is not as low, and add crown molding to make it appear more built-in
