No change: main and service -- green. A continuous cornice unifies the street facades of these three, 3-story brick buildings (523-27-29-31 Gov. Nicholls) which were constructed as store/residences in 1846. The two buildings at 523-27 Gov. Nicholls are separated by a wide porte-cochere that leads into the larger rear courtyard with its two service ells. These attached two-story service ells, which during the 19th century were connected by catwalks, form a U-shaped configuration. For the past 20 years until recently, this row of Transitional style buildings was the subject of extreme neglect and the subject of several lawsuits.
