My customer had a really good idea of what her built-in cabinet would be like, so we avoided all the back-and-forth time wasting that goes into the design stage.  The Bottom is basically closets and cubbies inside, with 110v outlet in each cubby for each of the 4 kid’s ipod, cell phone and PSP chargers, etc.  Next row up is the collectible level, with glass fronts and recessed quartz lights on a dimmer for display.  Top is storage for infrequently accessed stuff…Christmas ornaments, Grandma’s china, etc.  3/4″ MDF supersturcture hung on cleats to wall studs. Red Oak face frame.  Red oak custom factory ordered doors. wWater-borne poly satin finish.
