Our floor plan idea

We love our little house- but it is so darn little. We have a breakfast nook that we don't use at all and a laundry room off the kitchen that doesn't make any sense. The new floor plan will turn the breakfast nook into a small bedroom. Our old bedroom will become open to the common areas as a tv room. The akward hallway with 5 doors will be opened up. We plan on installing 6 craftsman columns where the old walls were. The laundry room will be gone and the kitchen extending to the Bush Street side of the house. We are planning to completely demo the termite infested garage and rebuilding it attached to the house. Hopefully with a small apartment on top. Pretty ambitious huh?
