Waltham office park acquired for over $80 million

Jumbo Capital Management and Sound Mark Partners have acquired the four-building, 270,196-square-foot Stony Book Office Park in Waltham for $80.058 million. The sale amounts to about $296 per square foot; the property’s seller, Clarion Partners, acquired Stony Brook Office Park for $55 million, about $204 per square foot, in April 2006. NKF Capital Markets represented Clarion in the most recent sale and procured Jumbo and Sound Mark as the property’s buyers.

Stony Book Office Park is 100%-leased and includes tenants such as Brainshark, DDJ Capital Management, Kluwer, Stanley Black & Decker, TIAA, Ultratech, Wells Fargo and Wolters. “Throughout our ownership of Stony Brook Office Park, the asset has consistently posted strong performance,” said Clarion Partners Senior Vice President Brian Collins in a prepared statement.

The property is positioned in a desirable office location, visible from Interstate 95/128 and convenient to Interstate 90 and the MBTA commuter rail. “Stony Brook Office Park enjoys a superior location in Waltham, suburban Boston’s strongest and most established office cluster,” said NKF Executive Managing Director Matthew Pullen in a prepared statement. “Additionally, the asset is well positioned among a high-performing competitive set that has consistently outpaced the overall market in terms of rental rate growth in recent years.”

New developer building 36 Allston condominiums approved in 2011

Penniman on the Park, a 36-unit Allston condominium building approved in 2011, is moving forward with a new development team comprised of Jumbo Capital Management of Quincy and investor Brad Spencer. The new development team secured a $12 million mortgage for 20 Penniman Road on August 19th, 2016 through East Boston Savings Bank; the project cost was pegged at $7.2 million upon approval in 2011. A building permit valued at $8.604 million was issued by the City of Boston on August 22nd, 2016 to general contractor Groom Construction to construct the 42,190 square foot Penniman on the Park.

The new development team also entered a lease on August 19th, 2016 for 14 parking spaces in an adjacent parking lot that will take effect upon the City of Boston's issuance of a Certificate of Occupancy for Penniman on the Park. An easement was also granted to the team by the owners of the adjacent lot; Penniman on the Park's underground parking garage will be accessed through the easement. At this time, a deed has not been recorded transferring ownership of Penniman on the Park to the new development team; this page will be updated with additional information as it becomes available.

In an interview with Banker and Tradesman, Spencer claims that the nearby Boston Landing development and associated MBTA commuter rail station due to open next year were key factors in the new development team's decision to invest in the Allston neighborhood. “The new commuter rail station is definitely the main impetus for us to pursue something there," said Spencer. "We see that area looking totally different in three to five years than it does today." A 93,000 square foot mixed-use building containing 80 rental residential apartments, a 562 square foot ground-floor retail space and a 1,715 square foot startup incubator space is currently under construction across from the Penniman on the Park project site at 61-83 Braintree Street.

Spencer also explained that the approved Penniman on the Park project will be revised to include all-steel construction as well as higher quality finishes than originally planned. Condominiums will be approximately 1,000 square feet in size with starting prices of approximately $650,000. Construction of Penniman on the Park will last approximately 14 months.
