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.

FASHION TOWER SCOPE . Design, approvals and construction administration of mechanical, plumbing, sprinkler, electrical and fire alarm systems. PROJECT COST . Home / Commercial FASHION TOWER ARCHITECT . GRT Architects PROJECT SIZE . PROJECT COST . SCOPE . Design, approvals and construction administration of mechanical, plumbing, sprinkler, electrical and fire alarm systems. Go Go GRT Architects recently completed the renovation and historic restoration of Fashion Tower, an Art Deco-era skyscraper in New York’s Garment District. The building was designed by Emery Roth, best known for his iconic pre-war residential towers including the San Remo and Beresford. Among the many buildings in what was once the epicenter of American clothing design and manufacturing, Fashion Tower is unique for its ornamental motifs referencing the apparel industry and for being occupied to this day by the garment trade. Motivated by the resurgence of the Fashion District and the building’s unique history, the current owner asked GRT Architects to restore the facade of the tower’s base while sensitively incorporating a contemporary lobby. Guided by Roth’s original drawings archived at Columbia University’s Avery Library, GRT Architects restored the exterior of Fashion Tower to its original splendor. Earlier renovations obscured a figured sandstone facade with layers of grey stucco and destroyed intricate detailing at the entry. Into a restored carved stone archway, GRT Architects added a minimal all-glass entry set back from the line of the masonry. True to Roth’s intentions, this portal is once again flanked by polychrome terracotta panels with peacock motifs— symbols of apparel, elegance and style. These peacocks rejoin surviving ornament that include winged putti holding shears and draping fabric, and women admiring their reflections and clutching spindles. A delicate façade cleaning revealed a richly veined sandstone cladding and forensic paint analysis was used to bring the appearance of cast iron spandrels and window frames back to the original. Inside, GRT Architects extended Roth’s stylized celebration of the fashion industry with a double-height lobby clad in pleated calacatta marble and bronze-tinted aluminum. The geometry of the lobby wall nods to folds in fabric while the scale and material palette play on the delicate balance between imposing and intimate that is a hallmark of New York Art Deco. Off-site CNC fabrication and on-site handcraft was used to realize a contemporary design in a classic material. Drawing upon the building’s history to prepare it for the next hundred years of service, the renovation reasserts the importance of fashion and style in a dynamic neighborhood.

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. Support services for residents, including seniors and formerly homeless individuals, will be provided by Breaking Ground through a partnership with the NYC Department of Health and Mental Hygiene.

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: 312 residential apartments. Notably, the project has pivoted toward 100% affordable housing, which may eventually involve a lottery through NYC Housing Connect. Monthly rents across the two developments are expected to range from $1,339 for a studio apartment to $2,304 for a three-bedroom residence. The projects will include indoor and outdoor recreation areas, fitness facilities and on-site laundry services. Additional information regarding apartment finishes and other resident amenities has not been announced. 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.

The building is in the preconstruction phase, with permits filed in December 2018 for a six-story residential structure. Size and Units: The development will feature 5 residential units across six stories, with a total residential space of approximately 8,173 square feet. Each unit averages about 1,635 square feet, suggesting spacious condominiums. Building Specifications: The structure will stand 68 feet tall and have a total area of 10,790 square feet, including non-residential space. It will be built with a steel-base foundation. Developer and Architect: The project is owned by Dharshyni Peries of LLS Number 1 LLC, with Kimberly Brown of Strata Architects PLLC listed as the architect. Location Benefits: The site is directly across from the Clinton Community Garden and near Hell’s Kitchen Park. It’s also close to the 50th Street subway station, providing access to the C and E trains. Historically, the address was associated with a four-story building constructed in 1910, containing 4 units, as noted in older property valuation data. However, the current project indicates that this older structure has likely been replaced or significantly redeveloped into the new six-story condo building.
