First of all I try to keep a good proportion of all the space for the main open space of the home, so I can not change the private area (bedrooms and bathrooms) that much. The most important thing that changed in the private area of the house is orientation in moving path. this orientation allows us to put the storage and laundry room between our spaces plus that it help us to make the middle bedroom a little bigger so we can great a space foe a home office in there. also we made a built-in-closet in the middle bedroom by taking some space from the grandmother's bedroom. the door of the smaller bathroom opens from the entrance space so it help less intervention of other people (guests, ...) in the private part of the house. the spaces in blue color in floor plan are for storing and book shelf and built in closet or any kind of shelf that the owners prefer. They are designed to enhance the capability of walls and spaces to keep or show more things that they could before.
