Communal by Nature

10 Stack Street at Hood Park
Charlestown, MA

As the first office building planned for the Hood Park master plan, 10 Stack Street is an ambitious, Class A structure of approximately 390,000 sf. Its design accommodates tenants seeking a mix of technologically advanced office and lab space while also incorporating below-grade parking, green amenity spaces, and retail programming at the ground level.

The building’s height of 232 ft, combined with its prominent positioning, grants an unencumbered sky view on the axis of Hood Park Drive and accentuates the historical “Hoods Milk” smoke stack – a beloved Charlestown landmark since 1928.

Organic Influences

Indigo Ag, initially an anchor tenant in Hood Park, had a major impact on 10 Stack Street’s design. SMMA architects are fashioning the building to be representative of the company’s international agricultural business, which includes organic seed technology for use around the world. Out of acknowledgement, the façade screen will take its cue from the precise geometry of rural agriculture. Imagine: an aerial view of a carefully planted crop, its corners cut perfectly, its straight rows receding into infinity. The form and materials of this façade embody Indigo’s motto:

“Harnessing nature to help farmers sustainably feed the planet.”

Evoking the Location

The 10 Stack lobby serves not only as a formal point of entry, but also as its own destination. Communal by nature, it provides a variety of perks to its tenants: a gathering of seating opportunities, intimate alcoves that establish a sense of privacy while still remaining connected to the broader space, and direct access to the street and greenery surrounding the building. From the exterior, the lobby appears modern and comprised entirely of glass, but its interiors — while still remaining lustrous — are reminiscent of Hood Park’s historic ties. Refined dark metals are contrasted by warm and inviting greys, wood types, and abstracted natural stone. The vertical planes of the space remain strong and direct, while focused lighting helps establish intersections of place much like the railroad tracks that were once present on the site.

Amenity Spaces

An extension of the lobby on the second floor opens up to a full coffee bar, which alludes to a series of amenity spaces that are available. These spaces, which encourage employee wellness, socialization, and relaxation, provide a high-value experience for both the user and the owner. Individuals can take advantage of a fitness center and yoga studio, play a game of foosball or ping-pong, or even enjoy an outside balcony that extends from the gaming area. The balcony itself overlooks and evokes the Stack Street Park, a new addition to the Hood Park landscape. Three adjacent conference rooms can also be converted into one large reception area, suitable for tenants hosting company events. A variation of bar-top seating and soft-seating throughout helps give employees an additional place to work or to simply disconnect from the stressors of a busy office environment.

10 Stack Street at Hood Park sustainability

Designed for Sustainability

10 Stack was designed to out-perform the stringent Massachusetts Energy Stretch Code, as well as to achieve a LEEDv4 Core and Shell Silver Certification. Primary energy savings are realized by a reduction in burned fossil fuels through daylighting design, the innovative use of lighting, and supported by a highly-insulated building enclosure. A combined on-site co-generation central plant serving the 10 Stack and 30 Stack facilities introduces a resiliency strategy through islanding capacity.


Water savings for the building are projected to be 30% over a conventional building: it is PV-ready and includes vegetated green roofs. Other sustainable features include access to public transportation, bike and shower facilities, and EV charging stations. 10 Stack also optimizes the use of sustainable materials such as FSC wood, recycled content, and regional sourcing.

Connecting the Park

The new building displays a kinship to the rest of the proposed Hood Park through rich symbolism and meaning. The massing of 10 Stack Street is divided into three vertical sections, establishing a rotation of the building in response to the circular smoke stack while also visually diminishing the longer axis of the building. The sections form a gentle concave shape with pleats and folds that embrace the street and its surroundings. The section closest to Hood Park Drive is the lowest in height: the building gradually steps up until it reaches its ultimate height at the northernmost section, thus calling attention to the new Hood Park’s enhanced skyline.
