Scott Payette Architects completes design for MBTA substation rehab into community access cable news station

Scott Payette Architects has completed the Egleston Square substation rehabilitation, the new headquarters for Boston Neighborhood Network, Boston's community access, education and cable news station. Located at an inner-city corridor in the geographic center of Boston, the television and media center appears poised to become a promising cultural and architectural "anchor" for Roxbury's Egleston Square neighborhood.
The 12,000 s/f building preserves a strong sense of the original, and the interior has been handsomely reconfigured and refit into new working spaces with many new elements that present a luminous counterpoint to the existing historic structure.
The $4 million project began two years ago, when BNN-TV and Urban Edge, a local non-profit developer, purchased an abandoned MBTA substation. The rundown building had been idle since 1986, a relic from the old elevated Orange line that served the Washington St. corridor for much of the 20th century. The structure presented an opportunity to recreate a community access and educational television studio for BNN and a revitalizing cultural center for this struggling community.
The clients asked Scott Payette Architects to produce a high-tech television environment, while preserving the historic exterior and crafting a LEED certified building.
The design approach retained much of the historic building fabric. The exterior brick and stucco, wrought iron fences and copper windows were restored according to National Park Service guidelines. The original exposed steel interior structure, wooden roof deck and monumental copper windows were kept. New elements and materials were added to complement the existing industrial architecture. Glass walls, light wells and double and triple height spaces were incorporated to preserve the volumetric character of the old turbine room. These oversize vertical spaces, with their many translucent to transparent elements and features also help bring natural light to the interior rooms, and generate an open and interactive studio environment. Energy and resource efficient systems, fixtures and building materials were used in combination with geothermal wells to reduce the building's carbon footprint and lower long-term operating costs.
The original building, a substation power plant, was an un-insulated triple height brick and steel structure with large windows at either end, but few on the sides. An additional floor was added, creating a double height space for the second floor TV studios. Light wells were created at the ends of the building to admit more natural light, and to accommodate an existing crane that had once been used to replace spent turbines. (The National Park Service required the antique equipment be preserved for the interest of posterity.)
On the second floor, the original metal roof trusses and wood deck were left exposed. The new mechanical systems, piping and lighting were also exposed, again reinforcing the industrial esthetic. As a counterpoint, new drywall, partitions, glass partitions, wooden door, carpeting and other finishes were added to produce a more comfortable and functional workplace.
On the first floor, the media lab and conference room, both major public areas, were designed with floor-to-ceiling glass partitions to allow natural light to radiate throughout the building, and to facilitate visual interaction between staff and visitors. Security and facility operations were given special attention.
Two geothermal wells were drilled to reduce reliance on fossil fuels and to eliminate the necessity for rooftop or site-mounted mechanical equipment. Energy and resource efficient systems, fixtures and building materials were used to reduce the building's carbon footprint and lower long term operating costs.
The project has received historic tax credits from the National Park Service and is applying for LEED-certified status.
