He might be the Father of Pioneer Square but Northwest architect Ralph Anderson is also responsible for some of the best mansions and luxury homes on Mercer Island. One such home, the 4-BR at 3005 69th Ave SE, has hit the market asking $1.375M. Perched on First Hill, the 1963 home provides all the requisite Seattle views you'd hope for. If you know Anderson's style, you know what you're getting. Big vertical windows, rustic Northwest-style wood interiors and wide-open spaces. Couple unique features include a beautiful, custom design on the front doors as well as (at least) two stained glass sections.
