What d33 design & planning does

D33 Design & Planning Inc. is a private architectural design and planning firm headquartered in San Juan Capistrano, California, that delivers residential community design, master planning, and construction support services across the Southwest United States. The firm serves three primary client groups: national and regional homebuilders (K. Hovnanian, Ashton Woods, Trend Homes, Blandford Homes), for-profit residential developers (Community Southwest, Coyote Springs Consortium, Culdesac), and nonprofit / mission-driven housing organizations (Linc Housing). D33's portfolio spans single-family detached homes, multi-family housing with demonstrated densities up to 180+ dwelling units per acre, mixed-use developments, community amenities, and master-planned communities ranging from infill sites (~6 acres) to large-scale projects exceeding 8,400 units (Mirielle Master Plan, Buckeye, AZ) and 7,355 units (Coyote Springs, Casa Grande, AZ).

The firm's service model is organized into four integrated stages: Planning Services (land analysis, zoning assessment, density studies, master planning), Architectural Design (residential typologies including affordable housing and senior housing), Construction Documentation, and Construction Administration. Notable technical capabilities include high-density affordable housing design (Blossom performs >10% above California's T-24 energy thresholds; Murrieta Infill achieves 30 DU/acre on 6.22 acres) and innovation in urban formats (Culdesac — the first car-free neighborhood built from scratch in the United States, a $200M 16-acre mixed-use development adjacent to light rail in Tempe, AZ). The firm claims more than 40 years of combined design experience in product design and master planning across a team of approximately 9 professionals led by partners Brian Weller and David R. Maldonado.

D33 operates a project-based professional services revenue model with quote-driven engagements and no publicly disclosed pricing. Go-to-market is sales-led and relationship-driven, supported by a portfolio-centric website; distribution is regional across Southern California and Arizona. The firm holds no institutional investment, patents, trademarks, or external ownership — it is partner-owned with no disclosed parent or subsidiary structure.
