Named for its address, 200 Clarendon St., this one-time conventional, third-floor office space is now a 45,000-sq-ft hospitality and wellness-infused club. The transformation added a fully equipped wellness center, multipurpose fitness studios, showers, locker rooms and various flexible meeting rooms as well as dedicated event and lounge spaces. Additional amenities include quiet work pods, collaborative seating areas, a wellness/mother’s room and hotel-style concierge support, all curated to create a high-end, client-first environment.
The design capitalizes on the building’s elevation with full-height windows overlooking a bustling plaza, filling the space with natural light and enhancing visual connectivity to one of Boston’s most iconic pedestrian areas. The lobby was also reimagined to better serve both clients and guests, improving flow and elevating the overall brand experience.

Adapting existing building infrastructure to accommodate new programming required close collaboration with engineers and trade partners to redesign mechanical and plumbing strategies within low floor-to-floor heights. Systems were routed through extremely tight interstitial spaces while maintaining system integrity for adjacent clients. Complex curved walls, ceilings and columns were constructed using custom glass fiber reinforced gypsum components, carefully coordinated with routing of building infrastructure. For the fiber optic “starry light” ceilings, the team devised a novel installation method by individually leveling each acoustic panel and threading fiber optic strands by hand.
To manage noise and minimize disruption to the building’s commercial clients and residential occupants, all high-decibel work—including demolition and core drilling—took place during off-hours and weekends. This approach required detailed phasing plans, coordination with property management and proactive communication to ensure seamless daily operations for those occupying the building.
Despite supply chain challenges, materials were sourced precisely, and any substitutions were carefully approved to preserve the space’s luxury aesthetic.
