SCOPE . assisted with securing Landmarks Preservation Commission approval for installation of rooftop equipment Go Go Development in the Riverside-West End Historic District Extension I went through several phases in the years between the 1880s and 1930s. The earliest phase between roughly 1885 and 1900 saw the construction of speculatively built row houses and flats for the middle and upper classes. By the turn of the century, developers began to focus on constructing larger apartment buildings as increasing construction costs ended row house construction, and the newly opened IRT on Broadway made the Upper West Side more accessible to the city’s expanding population. Legislation such as the 1901 Tenement House Act, the 1916 zoning ordinance, and the 1929 Multiple Dwelling Law contributed to the transformation in the scale of the streetscapes of West End Avenue, Riverside Drive, and West 79th and West 86th Streets where row houses and smaller buildings were replaced by newer, larger buildings.[1] 309-311 West 86th Street was commissioned as a hotel in 1912 by Weymer Hinckley Waitt- a railroad engineer turned hotelier, whose company later built the Weylin Hotel on Madison Avenue. The 12-story 40,000 square foot building was designed by Schwartz & Gross and completed in October of 1914 at a cost of $250,000. Originally known as Hotel Wayne until 1953 when it was converted into the Waldorf Nursing Home. In 1962 it became a residence club for senior citizens. Following interior alterations in 1979 the building was reconverted into apartments and became a co-op known as Stetson House. In 1984 John F Kennedy Jr. and Robert Littell moved in together into a 2-bedroom sublet at 309 West 86th Street. 309 West 86th Street is one of several Altera Engineering projects along the historic West End Avenue 347 West End and 915 West End. Altera Engineering was retained to provide engineering design and consulting services for the owners of the penthouse apartment. The project involved a full floor gut renovation.

In 2017 the Department of Housing Preservation (HPD’s) identified 87 vacant lots to be included into its New Infill Homeownership Opportunity Program (NIHOP). NIHOP seeks to promote mixed-income communities with affordable homeownership opportunities for moderate- and middle-income households earning up to 80-90 and up to 130 percent of Area Median Income (AMI). The program provides land and construction financing to qualified developers with the goal to build affordable condominiums for working families in low income neighborhoods. The agency’s goal is to spur neighborhood revitalization directly through infill of vacant lots and indirectly through creation of opportunities to own property in the areas where homeownership is beyond the reach of many residents. Altera Engineering is proud to be involved with a number of NIHOP projects. One of them- Rochester Suydam- consists of 3 clusters of 7 new buildings along Herkimer Street, Rochester, and Ralph Avenues in the Bedford Stuyvesant neighborhood of Brooklyn. The 7 buildings contain a combined total of 66 one- and two-bedroom apartments with a combined project size of 66,336 square feet. All the buildings within the NIHOP program are designed to a higher energy performance criterion than required by 2016 New York city Energy Conservation Code. Although the 66 units vary in layouts and sizes, all are provided with state-of-the-art central air HVAC and smart thermostats, thermally broken windows, Energy Star appliances, WaterSense plumbing fixtures, and LED lights with occupancy and daytime dimming controls. One of the biggest challenges for the design team was the budget. Because of HPD funding limits, each apartment had to be built for less than $ 70,000. Altera Engineering worked hand-in-hand with architect, sustainability consultant, developer, and vendors to carefully size and select MEP equipment while meeting energy efficiency and comfort goals of the project. Cooling and heating systems include residential single-zone ducted mini split systems, gas-fired condensing domestic water heaters. Fresh air is introduced into each apartment via energy recovery ventilators. Home / Multifamily ROCHESTER SUYDAM NIHOP ARCHITECT . PROJECT SIZE . PROJECT COST . SCOPE .

31 Lispenard Street is a modern condominium development in Tribeca, a trendy and historic area of Lower Manhattan known for its cast-iron buildings and upscale vibe. Development Overview: This is a new condo project by Urban Standard Development, a company specializing in ground-up construction and renovations. The building replaces an older one-story mixed-use structure from 1947 that had five units, two of which were residential. Building Specifications: Height and Units: A seven-story building standing 89 feet tall, with 5 residential units. Size: Total area of 12,603 square feet, including 10,362 square feet of residential space and 1,031 square feet of ground-floor retail. Design: Features a sleek, contemporary look with a conventional storefront and arched windows on the residential floors, blending modern gloss with Tribeca’s brick aesthetic. The architect is GF55 Partners, known for similar urban projects. Status: Full demolition permits were filed by 2018 for the prior structure, and by 2019, plans were presented to the NYC Landmarks Preservation Commission (LPC) for approval, given Tribeca’s historic district status. Renderings of both interior and exterior were unveiled around then. As of March 2025, it’s likely completed or nearing completion, though I don’t have real-time confirmation. No offering plan was filed by 2019, but Tribeca’s median condo price ($4.5 million) suggests these units would be high-end. Location Details: Address: Corner of Lispenard Street and Church Street, in the heart of Tribeca. Neighborhood: Tribeca (Triangle Below Canal Street) is famous for its loft-style homes, cobblestone streets, and proximity to SoHo. It’s a hub for art, dining, and luxury living. Nearby: Steps from Canal Street, the Canal Street Market, and transit options like the Canal Street subway station (A, C, E, 1 trains). Cultural spots like the Tribeca Film Institute are also close. Historical Note: Lispenard Street is named after Anthony Lispenard, who owned the land in the 18th century. The area evolved from meadows to a 19th-century trade hub, and now a chic residential zone. Additional Context The original building at this address was a modest 17-foot-tall structure owned by Peter Matera of Urban Standard Capital before its demolition. The new development reflects Tribeca’s ongoing transformation, balancing preservation (via LPC oversight) with modern luxury. Home / Multifamily 31 LISPENARD ARCHITECT . PROJECT SIZE . PROJECT COST .

30 West is a proposed new 100% affordable multifamily development. The site of the proposed Project is currently a municipal parking lot for community use, and the Village of Haverstraw has committed to enter into a 99-year ground lease with Westhab to facilitate the development. The Project will have a total of 79 units of affordable housing which will be priced at levels that are affordable to very low- and low-income tenants. It includes two levels of parking that will serve both building residents and the surrounding community. The Project is being developed through a public-private partnership with the Village of Haverstraw to address the growing challenge of high housing cost in Haverstraw and throughout Rockland County. 30 West will be a 100% affordable housing development with a focus on serving the hardest to reach members of the community. 23 of the units will be reserved for households at or below 30% of Rockland County’s Area Median Income (AMI), and between 15 and 20 of the 30% AMI units will be reserved as supportive housing units to serve formerly homeless individuals and families, individuals with mental health, and/or individuals with substance use disorders, among others. Services for the supportive units will be provided by Westhab, Inc, and referrals will be provided by Rockland County Continuum of Care, through the Department of Social Services and local community organizations. The remaining units in the Project will be designated for tenants earning up to 60% AMI. Residential amenities will include an on-site office for supportive services, a laundry room, a community room for tenant use, and an indoor/outdoor rooftop lounge overlooking the Hudson River and surrounding mountains. Through Westhab’s unique partnership with Cisco, the project will receive free hi-tech security and Wi-Fi equipment, lowering the cost of construction and providing free high-speed Wi-Fi to all residents. At the time of application, the Village did not have zoning regulations that would support the project. Working with the Village, we helped to draft a new zoning district that can be used for 30 West and for other affordable housing projects in the Village.

The project involves the infill development of three city owned blocks into affordable rental housing as part of the East Tremont Cluster project. This initiative aims to create three new affordable multi-family rental buildings on currently vacant sites in the Bronx. East Tremont is a neighborhood in the western Bronx, New York City, known for its rich history, cultural diversity, and working-class roots. It is part of Community District 6 and is bordered by the Cross Bronx Expressway to the south, Bronx Park to the east, and Third Avenue to the west. Between the 1940s and 1970s, East Tremont underwent major demographic shifts. A turning point came with the construction of the Cross Bronx Expressway, initiated by urban planner Robert Moses in the late 1940s. The highway displaced thousands of residents and split neighborhoods apart, leading to economic decline and urban decay. Many middle-class families moved to the suburbs, and by the 1970s and 1980s, the area faced rising crime and poverty. Starting in the 1990s, New York City launched major affordable housing programs to revitalize East Tremont and surrounding Bronx neighborhoods. Key initiatives included: -NYC Housing Preservation and Development (HPD) projects, which renovated or built thousands of affordable units. -Nehemiah Housing Program, which helped construct new affordable homes. -Public-private partnerships with nonprofit developers to convert abandoned buildings into viable housing. -New affordable housing developments, including those funded by HPD’s Neighborhood Construction Program (NCP). -Infrastructure improvements, such as better transit options and street enhancements. -Small business growth, with more restaurants, shops, and markets opening to serve the growing population. -Green space restoration, with nearby Bronx Park and Crotona Park receiving upgrades. The three development sites are located at 907 East 175th Street, 1900 Marmion Avenue, and 706 Fairmount Place. The proposed developments will collectively produce approximately 64 affordable rental units and one superintendent’s unit, totaling around 53,515 square feet of residential floor area. Of the 63 affordable units, approximately 16 will be designated as Affordable Independent Residences for Seniors (AIRS). Additionally, 10% of the total residences will be reserved for formerly homeless families and individuals. The project is funded through HPD’s Neighborhood Construction Program (NCP), which provides financing for the construction of infill rental housing with up to 30 units affordable to low-moderate, and middle income households.

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.
