Boylston Properties is a Boston based developer led by William McQuillan. With over 30 years of experience, the company has developed a wide range of successful projects including the development of corporate headquarters, retail, office, residential, research facilities, mixed use projects and hospitality. Over the last 10 years, Boylston Properties has concentrated its efforts in both Fenway and Watertown.

The retail component of the State Transportation Building in Park Plaza, also known as CityPlace, was Boylston's first project, developed in the mid 1980's. The Longwood Galleria in Boston's Longwood Medical Area, a $23 million project comprising hotel, office and retail was completed in 1987 in a joint venture between Boylston Properties and Children's Medical Center.

A joint venture of The Druker Company and Boylston Properties developed the 270,000 square foot, $50 million, corporate headquarters for Harvard Pilgrim Health Care at Rte. 128 / Rte. 9 in Wellesley in 2000. Boylston Properties completed construction of another new corporate headquarters building in 2000, for Cambridgeport Bank, on Soldiers Field Road in Boston.

Boylston Properties completed its first biotech laboratory building in Watertown in 2000, with a $6 million rehab for the headquarters for VITEX Corporation, a NYSE company, in a joint venture with The Cambridge Company. An acquisition of a five building complex of bio-tech uses in the Alewife section of Cambridge, again with The Cambridge Company in the summer of 2002, added to the Boylston portfolio.

In a 2006 joint venture with developer Samuels and Associates, Boylston Properties completed the development known as Trilogy, a retail and residential project spanning Boylston Street and Brookline Avenue in Boston's Fenway neighborhood. With 405 rental apartments, street level shops and restaurants, and below grade parking, this $213 million development has spurred new development in this neighborhood. Trilogy also included a build to suit 171 unit residential component built for Harvard University, and occupied by its Harvard Medical School graduate students, residents and staff.

In June 2013, Boylston Properties completed work on the Marriott Residence Inn Boston Back Bay – Fenway, a $68 Million, eight story hotel located between Fenway Park and the Longwood Medical Area. The 175-room hotel opened up in the summer of 2013.

In addition to its ownership of One Arsenal, Boylston Properties has been recently involved with the acquisition and development of three additional properties in Watertown including The Arsenal Project, 570 Arsenal Street, and 490 Arsenal Street.

The principals, Bill McQuillan and Mark Deschenes, are both experienced with the construction, development and management of a variety of real estate projects in Boston and elsewhere.

SQZ Biotech Signs 63,477 Square Foot Lease at Arsenal Yards

Boston-based real estate developer Boylston Properties has announced that cell therapy company SQZ Biotech has signed a 63,477 square foot lease at Arsenal Yards. With 200,000 square feet of lab and office space, Arsenal Yards is meeting the demand from the life science community for lab space in the East End of Watertown.

Set within an original 1800’s Arsenal historic building, with soaring 25’ ceilings, multiple boutique fitness operators, dedicated parking, and a private shuttle to Harvard Square, the new lab space is across the street from LINX, 185,000 square feet of new fully leased lab space, completed in 2018, also developed by Boylston Properties.

“When you look at the needs of life science companies and the advantages that the East End of Watertown provides, it’s not surprising to see Arsenal Yards becoming the place to turn to,” said Bill McQuillan, President of Boylston Properties. “We look forward to working with SQZ and seeing the company continue to grow.”

SQZ Biotech recently completed a $72 million Series C and expanded a clinical and commercial development collaboration with Roche. The young life science company will dramatically increase its footprint when it relocates from its current Watertown location to Arsenal Yards later this year. Utilizing the proprietary CellSqueeze® platform to develop a new generation of cell therapies, SQZ currently focuses on the development of novel treatments that leverage targeted immune modulation to impact oncology and autoimmune disease.

“For a young life science company, Arsenal Yards is an ideal location,” said Armon Sharei PhD, CEO and Founder of SQZ Biotech. “Being able to expand our operations while staying in Watertown was win-win for SQZ. We look forward to all the amenities that Arsenal Yards will provide our team.”

“This continues a trend of life science companies choosing to grow in Watertown's booming biotech scene,” said Duncan Gratton, Executive Director at Cushman & Wakefield. “This is our 6th new life science space lease in Watertown in the past 18 months.” Gratton and Elizabeth Donatoni of Cushman & Wakefield represented ownership, a joint venture of Boylston Properties, J.P. Morgan and Wilder, while SQZ Biotech was represented by Juliette Reiter and Mark Winters of Newmark Knight Frank.

Located on the Charles River in the dynamic East End neighborhood of Watertown, Arsenal Yards will be a thriving urban village with over 50 retailers & restaurants including Roche Bos. and the seven-screen Majestic Theater, over 300 contemporary residences, a 150-room Hampton Inn & Suites by Hilton, as well as office and life sciences space. The development will also include considerable open spaces throughout, access to a revitalized Arsenal Park, as well as connection to the Watertown-Cambridge multi-use bike path. Arsenal Yards is being developed by Boylston Properties, Wilder, and J.P. Morgan.
