Fallon Company raised the final beam of One Harbor Shore, a 122-unit luxury condo tower that completes the company’s extensive Fan Pier waterfront redevelopment effort.

Located along the Boston Harbor and the Harborwalk, it will offer luxury residences featuring waterfront terraces. The building will operate almost entirely on electricity and exceed Boston’s latest energy codes by 30%.

One Harbor Shore is the last part of Fan Pier, a 16-year transformation that saw parking lots fully re-developed into a mixed-use district in the Seaport neighborhood.

“Having been involved with Fan Pier from day one, it’s incredibly meaningful to see this final piece take shape,” said Richard Martini, executive managing director of The Fallon Company, in a press release. “This project was the result of decades of planning, public engagement and perseverance, and the outcome is a neighborhood that’s now central to Boston’s identity. One Harbor Shore is a fitting capstone that sets a new bar for urban mixed-use development.”

Presale has launched for One Harbor Shore condos and some of the residences will be offered soon through TCC. Construction completion is expected in August 2026.
