James Doyle Design Associates

What James Doyle Design Associates does

James Doyle Design Associates (JDDA) is a privately held, bespoke residential landscape architecture firm founded in 1993 by James Doyle and headquartered at 125 Greenwich Avenue in Greenwich, Connecticut. The firm designs high-end residential landscapes — ranging from small urban courtyards to large country estates — for affluent private clients, with a documented project footprint spanning the United States and Europe. Services span the full design lifecycle: site analysis, conceptual development, planting composition, landform design, materiality selection, and construction documentation, often delivered in collaboration with external architects (Scott Mitchell Studio, Ingrao Studio), structural and civil engineers, and municipal conservation and planning departments on complex permitting-bound commissions.

The core product is custom landscape architecture, and the underlying 'technology' is human design judgment rather than a software platform: licensed landscape architects (Connecticut, New York) with MLA credentials from Harvard GSD, Cornell, UVA, Penn State, and international programs produce hand-authored site plans, planting compositions, and construction drawings. Notable technical differentiators include regenerative-landscape methodology (soil regeneration, hydrological recalibration, invasive removal, native canopy reestablishment, intensive green roofs) applied to environmentally compromised sites, and integrated multi-disciplinary delivery on ecologically complex projects.

JDDA operates a sales-led, project-based professional services model with bespoke, non-publicly-priced engagements. Revenue derives from design fees on individual residential commissions, with no retained-revenue, subscription, or productized offering, and no disclosed external capital. Distribution is direct, founder- and principal-led, supplemented by an earned-media marketing stack that includes features in Architectural Digest, Veranda, Milieu, Luxe, Connecticut Cottages & Gardens, and The New York Times, plus authored and featured appearances in Phaidon monographs ('The Coastal Garden' 2026, 'The Contemporary Garden' 2025) and the firm's own 'Intersection of Nature and Art' monograph. The firm maintains no technology platform, no mobile app, and no APIs, and operates with a team of approximately 18.
