Stairway to second floor
Originally built as a telephone exchange in the late 1800s, the building had fallen into disrepair before the buyer purchased the shell, turning it into a home and office. The stairs wrap around a cylindrical form that provides a focal point for the house. Covered in roofing shingle, the shape and the material continue through to the doghouse on the roofdeck, visible in the exterior photos.
Interesting geometric shape tile. Could possibly be outside on wall
