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 .

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 .

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.

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. Altera Engineering's 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. Altera Engineering team had to work around existing occupied apartments to minimize disruption to tenants. Altera Engineering provided MEP engineering design and approval services for all mechanical, plumbing and electrical systems.
