It would have had an exterior staircase on the north side that led to the residence's entrance on the second level and a central staircase connecting the upper three levels. It had a dormered garret, which was later closed in and created a dark fourth floor attic that was not a habitable space.
In the 19th century, the exterior stair to the north was replaced with an interior three-story connector which combined 188 and 192 East Bay into one multi-suite building, accessed from this common corridor at each level. The ground levels of the two original buildings were converted to restaurants.
While the building maintained most of its original façade, much of the interior had lost its character, including its dormers and central interior staircase and was divided into a series of broken office spaces.
