WS Development unveiled plans for 55 Lansdowne Street, a new office building near Fenway Park. The 7-story, 250,000 sq. ft. structure will house the Red Sox and other ventures. The project is part of the Fenway Corners development, aimed at honoring the area's architectural heritage.

The view behind Fenway Park's Green Monster may soon change forever if plans to build an office building along Lansdowne Street become a reality.
The Boston Globe reported that at a Boston Planning and Development meeting on June 2, 2025, WS Development in Chestnut Hill unveiled renderings of its proposed project. Known as 55 Lansdowne Street, it includes a 7-story, 129-ft.-tall building encompassing up to 250,000 sq. ft. and an underground parking garage for 130 cars.
The project is part of the Fenway Corners project, which is slated to include a mix of eight buildings comprising office, research and development, commercial, residential, restaurant and retail spaces alongside Fenway Park, the venerable home of baseball's Boston Red Sox.
WS Development is partners in the venture with Fenway Sports Group, which owns the Red Sox and Twins Enterprises.
"While a formal agreement is still in progress, the current plan is for the building to serve primarily as the future home of the Red Sox and Fenway Sports Group's main offices, who are expected to occupy the majority of the space," a Fenway Corners spokesperson told the Globe via email.
The Green Monster is the popular nickname for the 37-ft.-high left-field wall at Fenway Park and is infamous for preventing home runs on many line drives that would clear the outfield walls of other baseball stadiums.
New Building to Be Paired with a Walkway Over the Turnpike
WS Development plans to construct the new office building on the site of what is now Lansdowne Garage and Fenway Park's storage facility, between the Cask N' Flagon and the House of Blues.
55 Lansdowne Street is designed to have retail space on its first two floors, with room set aside for office space up to the seventh floor. The developers will dedicate the penthouse to event and restaurant space.
Plans also include a pass-through from Lansdowne Street up to the second level on the northern side of the block, which could connect a future air rights project owned by Fenway Sports Group that will go over the Massachusetts Turnpike. A walkway is to be built over that section of the highway that would connect Lansdowne Street with Kenmore Square, according to WBZ-TV in Boston.
In addition, a mechanical box on the top of 55 Lansdowne Street will have a digital screen, where renderings show it rooting for the Red Sox.
Designers intend the brick on the back side of the building, facing the rail corridor and the turnpike, to embrace Boston's grittier character.
Yanni Tsipis of WS Development said the building will fit "really beautifully and contextually in with the streetscape [and] the Fenway Park ecosystem.
"It could have been a lot taller than this," Tsipis said. "[But,] we didn't think that was the right approach."
The Fenway Corners spokesperson admitted to the Globe that in addition to being visible above the Green Monster, the new 7-story building could affect views of the historic Citgo sign from particular areas of the baseball park.
"Views from certain angles will change with the addition of this building," the spokesperson said.
The proposed Lansdowne Street building, which could start construction in 2026 and take several years to complete, is the only project in this section of the Fenway Corners planning process. The Boston Planning Board already approved the other buildings west of Jersey Street in July 2024.
The project's developers said that their priorities for the new development include putting "people and bicycles first," respecting and preserving history and "avoid becoming a sports theme park."
When complete, the Red Sox and Fenway Sports Groups would move their office space to the new building, freeing up space in the ballpark that could be used to improve the fan experience.
Genevieve Day of The Fenway Alliance said at the June 2, 2025, municipal planning meeting that the proposal looks like a "huge improvement" over the parking garage that currently sits there, WBZ-TV noted.
"It really looks like one of those buildings that has always been there," she said. "It almost looks like a warehouse building that you are repurposing."
Fenway Corners to Preserve Fenway's Architectural Heritage
WS Development is stewarding the Fenway Corners plan — of which 55 Lansdowne Street is just one component — as it redevelops multiple sites in the neighborhood around the baseball park. The project will include approximately five acres adjacent to Fenway Park, located on Jersey Street, Brookline Avenue, Van Ness Street and Lansdowne Street.
On its website, WS Development said it "aspires to build community and activity via active streetscapes and new public uses, while respecting the historic fabric and significance of Fenway Park and the Richardson Building at the corner of Brookline Avenue and Jersey Street."
The entire effort will encompass approximately 2 million sq. ft. of commercial, residential, retail, restaurant and other uses across eight new buildings — each reflecting a distinct scale and architectural style. Several historic facades will be restored to preserve the unique character of Fenway's architectural heritage.
In addition, the redevelopment will eventually include more than 200 new homes and more than 40 retail locations, with a focus on supporting local businesses. Its centerpiece is a new, one-acre public open space at the heart of the neighborhood, achieved by making Jersey Street more pedestrian friendly and transforming it into a people-first, community space.
The project also will be designed to enhance transportation and public amenities such as the restoration of Arthur's Alley, improved connectivity to Lansdowne Station, new protected bike lanes and a bike hub, as well as upgraded sidewalks and landscaping.
