If you’re an architect Ghillino Adams Mohler and if it is 810 SF, one-story house in Seattle’s Queen Anne neighborhood. What do you do if one day you see that the house you live, no longer fit the needs of the family. Most people probably would sell and buy something bigger. Many painted fiber cement siding, a tight knot cedar feature wall board, plywood soffits, aluminum windows and a roof Zincalume sheet metal, has caused a real work of art. As for the relationship between interior and exterior, it faded with a double sliding door. Previously, one-story neighborhood, Ghillino has decided to extend the space by adding another level to the house and create two distinct areas defined by the cedar clad walls.
