O&S designed a new 4-story garment manufacturing building in Astoria, Queens, with textile production areas, office spaces, rooftop solar canopies, and compliance with NYC’s Energy Code and sustainable roofing requirements.

O&S Associates delivered full design services for H Mart's 35,000 SF space at American Dream Mall, completing a grocery area and food court with commercial kitchens, emergency systems, and public amenities.

It all begins with an idea.

Since 2016, O&S has provided architectural and engineering services for 1199 Housing Corp., a Mitchell-Lama cooperative, delivering façade and structural repairs, site work, and comprehensive compliance support under NYC HDC and HPD jurisdiction.
