This young couple's Seattle home was packed with charm but lacked space. Massive redwoods helped shade the house and provided privacy, but the trees made it impossible to expand the home outwards. So the couple decided to go up instead. Three new bedrooms and a stunning spa-like bathroom now sit on top of the original 1930s home. A new dining room, featuring grandma's antique dining table, was added to the first level, and the entire home received a fresh new paint job. The extra space and high-end details, like heated floors and a claw-foot tub in the bathroom, mean this couple will be able to enjoy their home for years to come.
