Rost Architects

What Rost Architects does

Rost Architects is a boutique, founder-led architecture and interior design firm headquartered in Irvine, California, specializing in luxury custom homes and accessory dwelling units (ADUs) for high-net-worth homeowners across coastal Orange County — primarily Dana Point, Laguna Beach, Newport Beach, and Corona del Mar. The firm operates as a licensed California architectural and interior design corporation under principal Mitchell Rocheleau, offering an integrated design package that bundles schematic design, design development, construction documentation, and construction administration with in-house interior design and site/landscape services. Notable technical components include Building Information Modeling (BIM) workflows and an in-house large-format 3D printing capability used for client visualization on custom home projects.

The business model combines professional services fees on bespoke residential projects with a smaller e-commerce stream selling pre-designed 'Luxury Villa' ADU plan sets as one-time digital licenses. Go-to-market is direct-to-client via website-driven consultation booking, a portfolio-rich content marketing program (articles, podcast), and earned media placements (NYT, CBS, Fast Company, LUXE RED Awards, Modernism Week Magazine, Palm Springs Life Magazine). Distribution is fully direct, with services delivered through individual engagements and digital products sold through the firm's own storefront, supported by Stripe payment processing. Customer segments center on affluent coastal homeowners, ADU property owners across multiple California cities, and select luxury residential developers, with project-based episodic revenue concentration typical of a 1–10 person boutique practice.
