B Five Studio

What B Five Studio does

B Five Studio is a privately-held residential architecture and interior design firm founded in 1981 in New York City. It operates as a small, studio-based practice (1-10 employees) organized around four principal designers: founding partner Ronald Bentley (Columbia M.Arch), founding designer Salvatore LaRosa (former Treasurer of The Architectural League, Parsons faculty, author of three books), Franklin Salasky (RISD alumnus, 40+ years in residential and commercial interiors), and Victoria Borus (Juilliard-trained, 200+ realized projects over 30+ years). The firm offers integrated services spanning architectural design, interior decoration, custom furniture design, landscape integration, and historic renovation, distinguishing it from single-discipline design practices by delivering cohesive execution from structure through furnishings.

The studio serves high-net-worth individuals and families commissioning primary residences, vacation homes, pied-à-terres, family compounds, and historic renovations across premium markets including New York City, Long Island, Westchester County, Connecticut, Pennsylvania, Maine, Miami Beach, Colorado, and Jerusalem. Client acquisition is sales-led, driven by referral networks, portfolio visibility through the firm website, design publications (notably an Elle Décor "Miami Marvel" feature in November 2011), and the individual professional credentials and Instagram presence of the principal designers. The firm carries no technology platform, software product, or proprietary AI/ML capability; it is a traditional bespoke design practice.

Revenue is generated through professional-services engagements on a custom quote-based pricing model, with no publicly disclosed fees, project minimums, or contracted recurring revenue. The firm has no external investors, no parent company, no funding history, and no documented acquisitions or partnerships. Ownership rests with the four principal designers.
