New plan

We looked at two ideas to add on a master bedroom+bathroom.  One, to build a second story above the current bedroom, two to expand on the ground behind the garage.  The going up looked pretty cool, but it would probably cost more, and if we want to age in place, then we would eventually come to the point where we couldn't get up the stairs.  We also just liked the flow with option two.  Here's what it looks like.
