Lawless + Mangione

What Lawless + Mangione does

Lawless + Mangione Architects and Engineers is a privately-held, full-service architecture and engineering firm founded in 1982 by Robert E. Lawless and headquartered in New York, with additional offices in Yonkers, NY and West Palm Beach, FL. The firm operates across six integrated practice areas marketed as sub-brands: L+M Architecture, L+M Structural, L+M Mechanical and Plumbing, L+M Electrical, L+M Energy, and L+M Resiliency. It serves five primary industry verticals — office and mixed-use buildings, co-ops/condos/multi-family residences, historic preservation and restoration, K-12 schools, and colleges and universities — providing services that span feasibility studies, building condition reports, design, construction documents, and construction administration.

The firm's technical core is integrated in-house A/E coordination rather than a proprietary technology platform. Differentiated capabilities include authentic restoration expertise on landmarked buildings spanning two centuries of structural systems, post-Hurricane Sandy resiliency planning, and NYC regulatory compliance (FISP/LL11, LL84, LL87, LL88, LL97). Notable project work includes the San Remo, Penn South, Loew's Paradise Theatre ($9.5M restoration), 55 Liberty ($2M terra cotta facade), Knickerbocker Village ($20M resiliency), Masaryk Towers ($28M underground boiler vault), and a 14-building, 1,632-unit electrical systems program ($17.3M) for Prestige Management.

The business model is project-based professional services with fees determined by scope and complexity; pricing is not publicly disclosed. Go-to-market is consultative enterprise field sales targeting building owners, managers, co-op boards, developers, government agencies, and institutions, supported by a corporate website, LinkedIn, and Facebook presence. The firm employs 60+ professionals with no external investment, no parent company, and no disclosed funding rounds.
