Cost to design a two-story addition to a home in Danville, CA

Scott, a homeowner in Danville, wanted to add to his existing property to give himself a comfortable living space that he could continue to use for many years. 

New Avenue's partner designer created a two-story addition for Scott to enjoy. Upstairs, the addition has a master bedroom and bathroom. Downstairs is a great room with a bar for entertaining. 

Scott calls this his "pied-a-terre."

To make room, an existing storage room had to be demolished. Parts of the existing home were removed. As you can see, the street view changed dramatically as a result of this addition:
