In order to give the most room for their bulk storage needs I am fairly certain I'm going to have to scrap the separate wall ovens in favor of a duel fuel range (induction top). This will allow plenty of tall pantry storage where the wall oven/microwave would have gone.
The children will have their own 'prep' area near the door to the garage. An under counter refrigerator and counter top microwave will be within reach so that they will be able to prepare their school lunches at night and not be in Marilyn's way as she's preparing dinner. I want to make the back splash in this area either a chalkboard or cork board so there is a message center to help this busy family without taking way too much wall cabinet space.
All the work aisles are 48" with the exception of the kids prep area, where I hope to have 60" to play with in case someone is in a wheelchair they can at the very least have enough room to turn the chair around.
