Studio Gang, the international architecture and urban design firm led by Jeanne Gang, and Henning Larsen, the international studio working across architecture and urbanism, announced today the completion of Breakthrough Properties’ One Milestone, a new hub for advancing science and research. Featuring distinct designs from each firm, One Milestone completes the first phase of Tishman Speyer and the Harvard Allston Land Company’s Enterprise Research Campus (ERC), a new mixed-use development in Allston.
Developed by Breakthrough Properties, a joint venture of Tishman Speyer and Bellco Capital, One Milestone is already attracting world-leading occupiers such as Roche's Genentech. The newly completed complex was recently awarded the 2026 Fitwel Best in Building Health Award after achieving Fitwel 2-star certification and is pursuing LEED Gold certification.
One Milestone creates a welcoming, flexible environment that encourages interaction, experimentation, and contemplation. Located on the southwest end of the ERC, the two-building complex is composed of One Milestone West, designed by Studio Gang, and One Milestone East, designed by Henning Larsen. Designed by Henning Larsen, a transparent, three-story atrium links the two buildings and enables interaction at every scale, providing amenities and collaboration spaces for occupants across both sides of the complex. Arrowstreet served as Architect of Record and Sustainability Consultant for One Milestone, translating the design teams’ vision into a high-performance life science environment.
As curated by the Breakthrough Art Program, the building features original works by artists whose practices explore the broad field of life sciences and foster collaboration across disciplines, integrating insights from science, technology, and the humanities to inspire interdisciplinary thinking and discovery. These include artworks by Ai Weiwei, Mungo Thomson, Eamon Ore-Giron, Lyès-Olivier Sidhoum, Ernesto Neto, Alexandre da Cunha, Goshka Macuga, Noémie Goudal, Jan-Ole Schiemann, and Analia Saban.
One Milestone marks Studio Gang and Henning Larsen’s latest collaboration on the ERC, which began in 2019 with their co-design of a strategic framework plan for creating a vibrant and inclusive public realm that brings the campus and surrounding community together. The building is part of the first phase of the ERC development effort led by the Harvard Allston Land Company and Tishman Speyer. The first phase of the ERC features four new buildings, all designed by internationally renowned architecture practices, connected by Allstonway, a SCAPE-designed network of public green spaces anchoring the district. In addition to One Milestone, ERC buildings include: The Atlas, a boutique hotel designed by Marlon Blackwell Architects that opened earlier this year; the David Rubenstein Treehouse, a new conference facility designed by Studio Gang that opened in October 2025; and Verra, a 343 unit apartment building designed by MVRDV that began welcoming residents last year.
“With One Milestone, we set out to create a hub for innovation that sparks connection and discovery. Studio Gang, Henning Larsen, and Arrowstreet were the ideal firms to accomplish this goal,” said Eric Stadelmann, Vice President, Design and Construction at Breakthrough Properties. “With its sustainable features, flexible labs, and collaborative amenities, One Milestone will advance the Allston life science ecosystem.”
