Environmental and graphic design for commercial interiors and exteriors in downtown San Diego's Harborview district runs through Persimmon Design's studio on West Ivy Street. The studio embellishes built environments using signage, architectural tile, and decorative elements while producing print-ready identity systems, packaging, and brochures — a dual environmental-and-print design methodology grounded in the same spatial-graphic integration principles that NewSchool of Architecture & Design teaches in its downtown program. Client scope ranges from individual boutiques needing logo-to-storefront identity systems to large corporations requiring coordinated wayfinding signage, branded wall treatments, and architectural finishes across multi-story commercial spaces. The open-plan Kettner Boulevard studio operates on a collaborative team model where concept sketches, material sourcing, and fabrication coordination move through shared workspace review rather than siloed departmental handoffs. Print-format deliverables including business cards, brochures, packaging, and large-format signage panels move from Persimmon's design files to PrintSteals Printing & Graphics for production, maintaining color-match accuracy from digital proof to final substrate. Highest-value projects involve complete environmental branding packages that integrate custom tile mosaics, dimensional lettering, illuminated channel signage, and coordinated interior wall finishes across multiple floors of a single commercial building.
