Epsilon is honored to be part of the groundbreaking transformation in downtown Boston. The conversion of 281 Franklin Street from an underutilized office building into vibrant new housing marks a major milestone – not only for the city, but for adaptive reuse and historic preservation efforts.



This project is the first to be completed under Boston’s new Office-to-Residential Conversion Program, which allows property owners to defer property taxes for up to 29 years when converting empty office buildings into housing. By reimagining existing space, this project not only helps address Boston’s housing needs but also revitalizes a historic structure and strengthens the surrounding neighborhood. Epsilon’s team of Historic Preservation Professionals secured state and federal historic tax credits for this important project.
Epsilon is actively involved in securing historic tax credits for many other office to residential conversion projects in Boston – including projects on:
- Devonshire Street
- Washington Street
- Court Square
- Portland Street
- Summer Street
- Congress Street
- Liberty Square
- and others….
