A Seattle proposal to add more housing above the historic Doyle Building near Pike Place Market is bringing out significant opposition, with nearby condominium owners seeking to utilize the only point of leverage they have: the city’s landmarks board. Clark/Barnes architects are working with the owners of the four-story building…. Their proposal would take advantage of a suite of newly approved state and city policies approved with the express purpose of making it easier to build housing. Architects propose retaining the facade and adding 12 additional floors of new construction. That new addition would consist of mass timber, allowing a smaller foundation and less weight on the historic building below.
