What Rlb Architecture does
RLB Architecture is a privately held boutique architecture and design firm founded in 1997 by principal Richard L. Blumenberg, AIA, and headquartered in Pacific Palisades, California. The firm specializes in high-end custom residential architecture, including new home design, additions, remodels, spec homes, and accessory dwelling units (ADUs and JADUs), serving affluent homeowners in the Los Angeles Westside communities — Pacific Palisades, Brentwood, Beverly Hills, Bel Air, Malibu, Santa Monica, and surrounding areas. The practice works primarily in traditional architectural styles (Mediterranean, Spanish Colonial, transitional) and emphasizes craftsmanship, personalized design, and client listening as core differentiators.
The firm's core offerings span the full architectural lifecycle: design and planning, drafting, permit acquisition, and construction administration with on-site oversight acting as internal quality control on behalf of the homeowner. Underlying technology is described as 'traditional design principles and craftsmanship' with no proprietary platforms, software products, AI tooling, APIs, or integrations disclosed. The firm does hold an online presence via a website portfolio, Houzz and Yelp listings, LinkedIn and Facebook pages, an email newsletter, and a free remodeling guide lead magnet, but there is no digital product offering.
RLB Architecture operates as a sole proprietorship under Blumenberg's direct control with no external investors, funding rounds, parent company, subsidiaries, or M&A activity. Revenue is generated through professional service fees on a quote-based, per-project basis, with no published pricing tiers. Go-to-market is sales-led via direct engagement, referrals from interior designers and prior clients, earned media coverage in design publications, and digital channels. Two physical offices are maintained in Pacific Palisades (headquarters) and Los Angeles (general office at 11500 Olympic Blvd).
