Here are sketches of our proposed addition. We are planning to bump out the existing kitchen/bathroom to the north about 10 feet and add a bathroom and laundry room on the first floor, then a bathroom and (gasp!) master walk-in closet on the second floor.
Feast your eyes on these babies! :) Aren't they beautiful?
The two potential layouts for the first floor laundry/bath...I'm partial to the one on the left because it has all that glorious counter space!
And the two potential layouts for the second floor bath/closet....these are very similar. I think the only difference is that the room sizes change a wee bit from layout to layout.
