In this view, looking west, the additions and terraces are shown above the existing Korn and Walker buildings. Unico Properties, Lake Union Partners and architect BuildingWork are planning to renovate and add to what's now known as the Korn Walker Block. That's a half block in Pioneer Square, anchored by the Korn Building at 119 Yesler Way, on the corner of Occidental Avenue South. The Pioneer Square Preservation Board will review those plans again on Wednesday, in a virtual meeting the public can also view by web link. Most of the buildings were originally developed circa 1890, soon after the Great Seattle Fire.
