Some great aspects are the new amounts of space and the loads of bright cabinets in each classroom.
Tile floors have been added under sinks so there isn't a permanent stain from spills. Teachers have bigger windows for more brightly, more naturally lit rooms. They also gained more control of the temperature because of the extra windows. The rooms have an eye toward the future with places for several computers. There are also large storage areas so, instead of having boxes lying around the room, teachers can tuck everything away.
