What OTL does
OTL Enterprises LLC is a New York City-based construction management and real estate development firm founded in 1985, operating as a privately held LLC with no disclosed institutional or venture capital backing. The company delivers four core service lines: general contracting and construction management, owner's representation, real estate development, and joint ventures, supported by modular services including pre-purchase estimating, planning and budgeting, and pre-construction management. Its project portfolio spans luxury residential construction (apartments, townhouses, penthouses, duplexes, lofts), commercial and hospitality buildouts (offices, retail, restaurants), and complex specialty work such as horizontal and vertical enlargements, landmark preservation, and major structural alterations. The firm reports having built and renovated over one million square feet of property in and around New York City across its history.
OTL's revenue model is built on project-based professional services fees tied to scope and complexity, supplemented by real estate development equity participation and development financing activities structured through joint ventures. Pricing is custom-quoted per project through a bid and estimating process that employs a proprietary two-step verification approach — one estimator analyzes architectural drawings and a second reviews scope quantities, with LEED compliance capabilities integrated into the workflow. The company is led by three principal partners: Angelo Cosentini (finance, legal, and development deal structuring, joined 1990), Paul Reehling (project management and estimating, joined 2004), and Jeff Harmatz (managing director, general counsel, and partner in all developments, joined 2005). Founder John Carson continues as project superintendent. OTL operates as a relationship-based, direct-sales enterprise, securing work through its network of NYC property owners, architects, designers, and developer counterparties — notably Avery Hall Investments and DelShah Capital.
The firm concentrates its operations in NYC, with primary activity in Manhattan and expanding presence in Brooklyn neighborhoods including Cobble Hill, Columbia Waterfront, and Downtown Brooklyn. Go-to-market relies on industry reputation, word-of-mouth referrals, professional features in publications such as the New York Times and Architectural Digest, and a Houzz professional profile (Best of Houzz 2015) rather than paid advertising. Customer segments span luxury residential property owners, commercial and hospitality developers, real estate developers, and select educational/community institutions on a horizontal segmentation basis.
