Wellington Square is a mixed-use complex containing retail, office and residential space on a site of a little more than an acre in the LowerThames Street National Historic District. The neighborhood developed after the Civil War and has been an area of mixed commercial, industrial and residential use for the last century, with typical concentration of commercial on the ground floor and residential above along the length of Thames Street.

The Architect's involvement with the project started with a failed attempt for a special exception from the Zoning Board of Review to allow apartment use in a Waterfront Business District. The Architect then developed a new strategy based on subdividing the site into five lots and using firewall construction to create separate but attached buildings that appeared as one. The concept developed in section with ground floor retail, second floor office space reached from a private supplemental stair directly off the sidewalk, and residential as a third floor walk up. It was directly influenced by the Architect's previous historical preservation work on several 19th century commercial blocks in Newport. This section allowed the three story configuration within a 35 foot height limit and set the tone for a massing appropriate for the small scale fine-grain neighborhood.
