Hartman Design Group

What Hartman Design Group does

Hartman Design Group is a U.S. commercial interior design and interior architecture firm specializing in multifamily residential, senior living and active adult, affordable housing, model home, and hospitality properties. Founded in 1986/1987 and led by Founder & CEO Phyllis Hartman, the firm operates from a Rockville, Maryland headquarters and a Tampa, Florida office, serving real estate developers, owners, and property managers nationwide across new construction, adaptive reuse, and historic renovation engagements. Its service offering spans space planning, FF&E procurement, branding and identity development, and art curation, anchored by domain specializations in biophilic design, adaptive reuse, and wellness-focused environments. The firm is 100% women-owned and WBE-certified.

The business model is project-based professional services delivered through direct enterprise sales: HDG is engaged by institutional real estate clients (including Bozzuto, BXP/Boston Properties, Mill Creek Residential, Berman Enterprises, Monument Realty, Kimco Realty, SCG Development, and others) on individual development projects, with pricing customized to scope and not publicly disclosed. Go-to-market is relationship-driven and reinforced by a portfolio of 820+ completed projects and 128+ industry awards across NAHB, NAIOP, GALA, Delta Associates, ULI, and Washington Business Journal, plus thought leadership in Multifamily Executive and a presence on LinkedIn, Instagram, and the firm website. The underlying "technology" is design craft and project execution capability rather than software or AI; no APIs, proprietary platforms, or AI/ML capabilities are offered. HDG is a bootstrapped private firm with no disclosed funding rounds, acquisitions, or institutional investors.
