 The upper levels consist of three wood-frame houses, each 2-1/2 stories in height, thus giving the building as a whole a height of 3-1/2 stories.In the gaps between these houses are stylistically linked single-story flat-roof wood frame commercial elements.The oldest portion of the block is the easternmost house, built about 1797 for John Upton, while the other two houses date to about 1835.
