Goal: Use as office/den and then guest bedroom for overflow of guests. Also the possibility to store larger exercise equipment.
I like the idea of built in shelves with counter top underneath. This might work nicely in the back bedroom. A nice compliment would be a Murphy bed for additional guests that is built into the bookcase/cabinets.
Here is the idea of the Murphy bed built into the cabinets/shelves
I like the multiple build-ins to hold books (of which, we have a lot).
I like the color contrast - white cabinets and molding with hardwood floors and peanut colored paint on the walls.
I like the idea of using the same basic color frames and mats for all the family pictures that could hang on the walls either in the den/office or down hallways
