Celtics' Arena to Undergo €85 Million Renovation

Delaware North, owner of TD Garden—home to the Boston Celtics and the NHL's Boston Bruins—has announced extensive renovations to the arena. Opened in 1995 as a replacement for the iconic Boston Garden, the venue previously saw its spectator capacity increase from 18,624 to 19,156 in 2019.

This $100 million (85.33 million euros) investment will span the next three years. The project primarily focuses on a complete overhaul of the arena's 83 luxury suites, as well as the premium clubs catering mainly to season ticket holders located at court level.

This marks the most significant renovation since the arena's inauguration. While there have been periodic updates over the years, none have matched the scale of the current undertaking. The goal is to create a consistent, high-quality experience for both sporting events and concerts, with TD Garden projected to host 60 concerts in 2026.

To conceptualize the new premium experience, executives from Delaware North, TD Garden, the Celtics, and the Bruins leveraged internal data and external feedback. They implemented the SuiteX process, a methodology developed in Boston by Delaware North, drawing on its in-house sales and hospitality expertise. The offering will be further enhanced by a new culinary program in the suites, developed by Patina Group, also part of Delaware North.

The renovation project involves several companies. Rockwell Group is responsible for the court-level design, with full details yet to be released. SCI Architects and Gilbane are handling the suite renovations, with work set to begin this summer during the NBA and NHL off-season, starting with one-third of the Boston Garden Society suites.

With this new project, Delaware North's total investment in the arena will exceed $500 million (426.67 million euros). This figure includes the 2019 project that created the Boston Garden Society but does not encompass The Hub on Causeway, a $1.2 billion mixed-use development located adjacent to the venue.

It's worth noting that a strip of commercial, office, and residential buildings on the main facade of TD Garden completely obscures the exterior view of that side of the arena.

The specific rent the Celtics pay Delaware North for using TD Garden is not public, as the two entities have ownership ties and a private lease agreement. However, in 2021, the Boston franchise extended this long-term agreement until 2036. The Celtics are currently one of only 11 of the 30 NBA clubs that do not own the arena where they play.

Recall that in August 2025, the Celtics, whose largest shareholder was the Grousbeck family, sold 51 percent of their shares to STG Partners, owned by billionaire Bill Chisholm, for $6.1 billion (5.2 billion euros). When nearly all ownership transfers to Chisholm—who has Rob Hale and Brice Deal as co-owners—in 2028, the total transaction will amount to $7.3 billion (6.23 billion euros). This was a record at the time, though it has since been surpassed by the Buss family's sale of the Lakers to Mark Walter for $10 billion (8.5 billion euros).
