City House is a historic preservation and adaptive reuse project in the heart of Baltimore’s Mount Vernon. The original building was designed by Joseph Evans Sperry — a well-known Baltimore architect — as the city residence of William Marburg, heir to a tobacco fortune. SM+P’s scope encompassed retaining and preserving the ornate character of this 16,000 square foot mansion while converting it into a functional, modern, desirable multi-tenant office building. Construction phasing, budget constraints, and historic tax credit stipulations added significant complexity — all of which SM+P navigated successfully. A defining example of what the firm does best: finding the future in historic buildings.
