In Seattle, they just modified buildings to have entrances on the 2nd floor, and raised the sidewalks, leaving the 1st floor as a basement.

Chicago has some of that too, northwest of downtown.

Yeah, you can find a lot of houses like that near Division and Milwaukee, more towards the Kennedy.

Would love to learn more about how they actually got the jackscrews under the building. Did they carefully knock out part of the foundation and placed the jackscrews there? What about the parts of the building that were not at the edges; did they place the jackscrews at the edges and then dug under the building and placed the other jackscrews there? The Briggs House illustration from the bottom of the Wikipedia article, seems to shows beams of wood or concrete/stone at the bottom of the building. Wonder if they were there from the start, or put there when the jackscrews were inserted?
