I love the idea of having the 2 extra kids bedrooms where one could be converted into a walk-in after they are grown. But that's just me looking at the future.

Really, it all depends on the size of your house & lot. I am on almost 2 acres, so adding onto our house if we wanted a 2nd level, workshop, etc is only limited by time.

The closet I have now was actually part of a past MB expansion. When they enlarged the bed area, they put in a false-wall behind the master bed area allowing for a walk-through closet. If you have enough space, this could be done in any large room or garage area. Just keep in mind that any built-ins to a garage will have to be insulated to protect against excessive moisture issues.
