D. A. Dunlevy

What D. A. Dunlevy does

D. A. Dunlevy is a privately held landscape architecture and construction firm founded in 1982 and headquartered in Poolesville, Maryland. The company delivers design-build services for high-end residential properties throughout the Washington DC, Maryland, and Virginia metropolitan area, with secondary work for healthcare and nonprofit clients (notably healing gardens for end-of-life care). Its service stack spans three layers — landscape design, construction of outdoor living environments (pools, water features, outdoor kitchens, patios, pavilions, fire pits), and ongoing horticultural maintenance — operated as a single integrated lifecycle offering.

The company's underlying capability is craft-based rather than technology-based: in-house landscape designers and horticulturalists are the primary differentiator, and curated project galleries (Georgetown, Bethesda, NW DC, Woodbine) are positioned as portfolio evidence of design quality. There is no proprietary software, no API surface, and no documented AI or data capabilities; pricing is quote-based per project and is not publicly disclosed. The go-to-market is direct engagement with homeowners, supported by a content marketing program (project gallery and a category-rich blog) that serves top- and mid-funnel demand generation in the affluent DC metro market.

The revenue model is project-based with custom quote pricing, supplemented by recurring maintenance contracts. The firm is independent and owner-operated, with no disclosed institutional investors, parent company, M&A activity, or funding rounds.
