Many examples of the common storefront addition involve the construction of connected one- or two-story buildings in the lawn space of houses and flats. However, in neighborhoods east of Grand, many early converted buildings stood at the sidewalk line. Here, the best way to create commercial space was through the insertion of storefront openings in existing front elevations. Typically, cast iron columns and combined beams would "jack" the new opening in the brick wall. Often, floor levels inside of the building would be altered to draw the shop floor down to sidewalk level from is common position at the head of foundation walls.
Two examples of similar buildings from different neighborhoods illustrate how this practice happened across the city.
