Summary
Brian Whitmer, Co-Founder and Managing Partner of Doors & Spaces Industrial, has been named a 2026 "Ones to Watch: Innovator in Commercial Real Estate" by the New York Real Estate Journal (NYREJ). The recognition, as described in a company-issued release, highlights Whitmer's work in institutionalizing the small-bay industrial sector.
Doors & Spaces was co-founded by Whitmer alongside Managing Partners Jonathan Weinstein and Matthew Dietrick. The firm was established to address a market disconnect: while large-scale industrial centers have dominated past real estate cycles, small-to-mid-sized enterprises have faced a scarcity of efficient, locally focused industrial space. The company states that recently constructed SBI stock remains significantly undersupplied in key geographies, including the New York Tri-State Metro and high-growth Southeast markets.
The firm applies institutional-grade development, capital markets discipline and modernized operations to a sector historically characterized by fragmented ownership. Whitmer describes small-bay industrial as the "apartments of industrial." Doors & Spaces targets infill sites near housing density and major transportation corridors, where barriers to entry, complex zoning and rising construction costs have traditionally limited new supply. The team, which draws on founders' backgrounds in capital markets brokerage, Wall Street finance and construction, acts as a strategic asset partner, optimizing interior configurations, power capacity and site functionality for tenants.
Current activity is concentrated in eastern-seaboard markets. Recent acquisitions include a six-building portfolio in Middlesex and Dunellen, NJ, and multiple assets across Voorhees and West Berlin, NJ. Construction is underway in Egg Harbor Township, NJ, multiple locations in Upstate New York, and Callahan, FL, a submarket within the Greater Jacksonville area. The firm pursues both ground-up development and existing-asset acquisitions, and states that its technology platform allows it to optimize leasing and bay functionality for trade contractors, light manufacturers and local distributors.
The company describes itself as a premier small-bay industrial investment, development and management platform rooted in the New York/New Jersey metro that has expanded into other national markets. The release is sourced from Doors & Spaces and has not been independently verified.
