All on one floor! Personal changes: make the office into a fourth bedroom, turn the jack & jill bathroom into two bathrooms, make the guest room a combination library/guest room with entry from the foyer and hallway, add a basement and move the fema-approved safe room there for increased weather protection. I do not care for the outside design of this house at all, so I would warm it up by repositioning the garage and adding on a wide, covered front porch to resemble a sprawling farmhouse.
Some colors I used last season were Silver Strand (light blue gray), Mindful gray, Oyster Pearl, Passive Gray, and Intellectual Gray. I also like soft greens and richer blue tones. A good clean white is nice for trim because it makes the wall color pop. I use oil based paint on all my cabinets and trim so it is easy to clean. I always like to get samples and put them up on the wall before I determine what color to go with.
