A 13-story building at 67 Meserole Street is a significant project for East Williamsburg, especially given its shift toward 100% affordable housing. Here is the current state of play as of February 2026: Project Status & Timeline Permit Phase: The new building permits filed in July 2025 by SD Builders and Construction (designed by Aufgang Architects) have moved through the initial Department of Buildings (DOB) review. Brownfield Cleanup: Because the site was historically used for fuel storage and construction equipment, it entered the New York State Brownfield Cleanup Program. Remediation work (cleaning up the soil and groundwater) is a prerequisite for residential occupancy and has been the primary focus throughout late 2025. Construction Progress: Heavy machinery for foundation work and "shoring" (securing the ground for the deep cellar) is expected to be active on-site throughout early 2026. The Building Specs Height: 13 stories (approx. 124 feet). Units: 80 residential apartments. Notably, the project has pivoted toward 100% affordable housing, which may eventually involve a lottery through NYC Housing Connect. Ground Floor: Roughly 6,500 square feet of commercial space, likely intended for a neighborhood-facing retail tenant or community facility. Design: Expect the signature Aufgang Architects style—likely a mix of modern brickwork and large windows to blend the industrial history of the block with modern residential needs.

SCOPE . full MEP/FP design and construction administration services Go 42 SHARON STREET, BROOKLYN A ground up construction of a single family home in Brooklyn. Altera Engineering was retained as a project’s MEP engineer in part because the building’s complex interior geometry required a thoughtful approach that most small MEP firms lack. Altera Engineering consulted the owner on high performance building strategies, such as passive heating and cooling, insulation and envelope air-tightness, intelligent lighting controls, highly efficient domestic water heating and continuous ventilation with energy recovery. With the exception of domestic water heating, the building does not use natural gas or any other fuel for heating, and is cooled and heated with a variable-refrigerant flow system. Highly insulated envelope, and fuel free heating are expected to save 15 metric tons of Carbon Dioxide emissions on an annual basis. Altera Engineering efficiently and successfully secured utility connection approvals and assisted the client in resolving filing and approval issues.

Design, approvals and construction administration of mechanical, plumbing, sprinkler, electrical and fire alarm systems. Go Go 915 West End Avenue is a 120,000 SF 15-story multifamily building commissioned by a prolific upper west side builder Joseph Paterno (whose initials were inscribed above the entrance), designed by Rosario Candela and completed in 1922 at a cost of approximately $625,000. The building was designed in Renaissance Revival style, and is laid out as two wings around a central core with outer court. Boiler room, laundry facility, oil tank, and incoming services are located in the basement. Lobby and 94 apartments are located on floors 1 through 15. In 2015 the building was included into Riverside-West End Historic District Extension II, and is subject to certain Landmarks restrictions. Following the $ 85.5 million acquisition by a group of investors, Altera Engineering was retained to evaluate the existing heating, plumbing, gas and power distribution systems. Our engineers worked closely with the owner’s architects and marketing team to identify and carry out short payback upgrades to support the investors’ conversion and repositioning program to the ‘best-in-class’ multifamily rental. 915 West End Avenue is one of several Altera Engineering projects along the historic West End Avenue, 347 West End and 309 West 86th Street.

The development was acquired for $255 million, with total project costs projected at $500 million. Work will be funded through a mix of public and private financing, including New York State’s Housing Our Neighbors With Dignity Act (HONDA), New York City’s 15/15 Supportive Housing Initiative, HDC tax-exempt bonds, and HPD’s Supportive Housing Loan Program. Additional support includes financing from Wells Fargo, JPMorgan Chase, the Low Income Investment Fund, LISC Fund Management, and the Corporation for Supportive Housing. Historic and Low-Income Housing Tax Credits and transferable development rights have also been utilized. The Stewart Hotel, a 31-story building shuttered since 2022, is anticipated to take around 24 months to complete renovation. Construction will include merging adjacent rooms to create apartments, replacing mechanical systems, installing LED lighting, and building on-site social services offices.

Home / Landmarks 712 BROADWAY ARCHITECT . PROJECT SIZE . PROJECT COST . SCOPE . MEP engineering design and approval services Go Go 712 Broadway is an 8-story landmarked building located in NoHo (North of Houston) historic district. The iron frame, granite and terra-cotta building was constructed as a warehouse in 1893 for the Scholle Brothers. The commercial building designed by Alfred Zucker replaced an 1803 3-story Federal-style mansion, which the Scholle Brothers bought for $88,000 in 1890. NoHo saw its first development by the first decade of the 19th century when John Jacob Astor acquired a large tract of land between Great Jones Street and Art Street (now Astor Place). From 1820 to 1840 the area developed as a fashionable residential district lined with lavish Federal and Greek Revival style residences. New York University was founded in 1831 in nearby Washington Square. Altera Engineering provided MEP engineering design and approval services for a loft apartment, working closely with architects and owners to integrate state-of-the-art mechanical systems into the existing historic features of the apartments.

HVAC, sprinkler, plumbing and electrical power design and construction administration Go Go BROOKLYN NAVY YARD When an established Brooklyn based coffee company decided to consolidate its roasting and shipping under one roof, they retained Altera Engineering to help them bring their vision to reality. Founded in 2009 in a Brooklyn loft, artisanal coffee purveyor- Brooklyn Roasting Company- has consistently been ranked as top 5 coffee places in Brooklyn (Yelp), one of 10 best coffee shops on New York City (Gothamist) and best local brew of 2015 (Gothamist). BRC prides itself on sourcing locally grown, organic fair trade coffee beans. It is no surprise they decided to locally source engineering services as well. BRC came to Altera Engineering because their previous consultant was not responsive to their needs and was too expensive. Brooklyn Navy Yard is a former US Navy shipbuilding yard spanning 300 acres on the East River in Wallabout Basin. Following its closure in the mid 60’s, the yard was re-opened in 1969 as an industrial park. Since 1989, the site has seen economic development spurred by the city’s investment. Today, more than 200 businesses operate at the yard and employ about 5,000 people. Brooklyn Roasting Company decided to take up a 16,000 SF space in the Navy Yard to consolidate its roasting operations. On most projects, clients come to their engineers with defined design criteria. In the case of BRC, the client did not know how to best program the their new facility. There were plans for an office, packing, roasting, and shipping and even performance space functions. Our engineers worked closely with the client and architect to learn BRC’s business model, ins and outs of a coffee roasting process and the client’s future plans in order to help the client define present and future performance requirements of the space. Altera Engineering was retained to provide consulting, engineering design and construction administration services for BRC’s new facility. The project involved specialty HVAC systems for coffee roasting production plant. Altera Engineering prepared documents for State Historic Preservation Office filing.
