326 Rockaway Avenue was one of several sites developed as part of the Brownsville Plan, an initiative aimed at creating over 2,500 new affordable homes representing more than $1 billion in housing investment for the neighborhood. New developments on city owned land support broader goals of improving health, safety, economic development, and the arts. This includes a new cultural center, a center for innovation and entrepreneurship, and new neighborhood retail and community spaces, all integrated with affordable housing. Beyond housing, the Brownsville Plan coordinates over $150 million in City investments, including renovations of local parks, enhancements to open spaces in NYCHA developments, a new community center for teens at Brownsville Houses, and a Neighborhood Health Action Center. The initiative seeks to revitalize city owned vacant sites, increase neighborhood services and amenities, and stimulate economic growth in an underdeveloped part of Brooklyn. As part of this effort, the 326 Rockaway Avenue development created 215 permanently affordable apartments for low income New Yorkers. Of these, 130 units are designated for formerly unhoused young adults and their families, who will have access to onsite supportive housing services provided by RiseBoro’s expert staff. These services include personalized case management, life skills development, counseling, crisis intervention, employment and education referrals, and opportunities for community engagement and leadership. Additionally, RiseBoro staff will offer mentoring and empowerment programs in collaboration with the nonprofit’s education initiative. Considered one of the most sustainable affordable housing projects in New York City, the mixed use development was designed to meet Passive House standards and achieve PHIUS certification. The all electric Passive House project will incorporate rooftop solar PV equipment and will use zero fossil fuels for heating and other operations. The 181,324 square foot building will feature 3,800 square feet of community space, 1,600 square feet of ground floor retail, and a mix of studio, one, two, and three bedroom apartments. Common area amenities include a fitness center, a community room, a yoga studio, a children’s playroom, laundry facilities, outdoor recreational areas, a roof deck, and bike storage. Financing for the $146 million project includes Low Income Housing Tax Credits, tax exempt bonds, an acquisition loan from the Corporation for Supportive Housing, and support from the New York City Department of Housing Preservation and Development, the New York City Housing Development Corporation, and the Goldman Sachs Urban Investment Group.

Full MEP/FP design Go Go Full gut renovation and rear addition to a landmarked townhouse located in Brooklyn’s Park Slope Historic District. The history and development of the Park Slope Historic District is closely related to that of Prospect Park. The area encompassed by the park and the Historic District was the scene of a major battle in the revolutionary war between the Continental Army under George Washington and the British Army in August of 1776. At that time and until the 1850’s this area remained essentially rural, consisting largely of farmland with rolling hills to the east. In sum, the completion of Prospect Park and construction of the Brooklyn Bridge in 1883 were the two major factors in the development of the area. Carroll Street- named after Charles Carroll, a signer of the Declaration of Independence- is one of the most serene and charming streets in the District. 848 Carroll is a neoclassical four-story red brick with limestone trim, was designed by William B. Greenman and completed in 1905 and described in the AIA Guide to New York City as “a narrow bay-windowed neo-classical exile from the Upper East Side” Altera Engineering worked closely with the architect and owners to seamlessly integrate all new building infrastructure into the existing shell.

Designed by the prolific Upper West Side architect George F. Pelham for the developer Joseph H. Davis, this building was constructed in 1906 as a small multiple dwelling (flats) and once known as the Albea. Located on the north side of West 93rd Street ninety-eight feet east of Riverside Drive, this six-story building faced in red brick with ironspot headers and stone trim is seventy-five feet wide and dumbbell-shaped in plan. The facade is capped by a modillioned metal cornice. An original wrought-iron fire escape is located at the center of the facade. The owners retained Altera Engineering in their bid to renovate and reposition the building as an upmarket rental property steps away from the Riverside park. Engineering scope included gut renovation of all vacant apartment units and building systems upgrade. A new high efficiency condensing boiler plant was designed to replace an outdated (once coal-fired) steam system. To fully take advantage of the condensing boiler efficiencies, all new hydronic radiators were selected around low water temperatures. Variable speed pumps were selected for low flow, wide delta-t of the water to minimize motor horse power. Domestic water was upgraded with indirect water storage tanks fed by boilers via plate and frame heat exchangers. The Altera Engineering team had to work around existing occupied apartments to minimize disruption to tenants.
