Floor 1 - I would take out one of the bathrooms between the bedrooms and the wall for a Jack and Jill bathroom. Also needs a big shower in master bath, and not crazy about the master suite sharing a wall with the living room.
Large 5 bedroom family home to show you. It's a good size and would suit the growing family. The guest bedroom could be used as a teenagers retreat. The master is spacious with its own living area and huge WIR behind the bed.
