420 Yale Avenue North

   Type:  Multi-Family

   Location:  Seattle, WA

   Project Size:  146,000 sq ft

   Year Designed:   2000

   Architect:  Driscoll Architects



This multi-family project in Seattle has five levels of concrete construction a slab on grade and four levels of post-tensioned concrete slabs.  The concrete levels are connected with vehicular ramps.  Transfer girders collect the ramp and slab loads and carry them to concrete columns.

The superstructure steps back as it rises from the street level, reducing building mass so that it would not overwhelm the neighboring St. Spiridon Orthodox Cathedral.  This superstructure steps create framing complexity at plan changes from floor to floor.  Steel girders work within the overall timber framing in order to carry the collected loads to common bearing points
