Chantal Lamberto Interior Design

What Chantal Lamberto Interior Design does

Chantal Lamberto Interior Design is a privately held, founder-owned residential interior design studio founded in 2007 and headquartered at 3376 Sacramento Street in San Francisco, California. The firm serves high-net-worth residential clients undertaking meaningful home transformations, including whole-home renovations, custom millwork, kitchen and bath design, and fully furnished turnkey interiors. Its core service offering spans three stages: high-end renovation and interior design, early-phase architectural integration alongside architects and builders, and curated furnishings with layered interiors through procurement and white-glove installation. Geographic reach is coast-to-coast across San Francisco Bay, Carmel, Boston, New York, and Nantucket.

The business operates as a boutique professional services firm with a team of five, led by founder and principal Chantal Lamberto, whose background combines Urban Studies & Planning with a historic preservation focus (UCSD) and Interior Design & Interior Architecture (UC Berkeley). Technology footprint is limited to Studio Designer, a standard project management platform used by design studios. GTM is sales-led and relationship-driven, with client acquisition supported by earned media in House Beautiful, Architectural Digest/AD PRO, Elle Decor (including the Spain edition), Luxe Interiors + Design, Sunset Magazine, Modern Luxury Interiors Boston, 25 Beautiful Homes, MyDomaine, and Rizzoli book publications (2022 and 2025), plus Instagram accounts for interiors and the founder's Ceryak Art practice.

Revenue is generated through design fees and markups on furnishings procurement, with engagements custom-quoted per project. The firm also operates an online storefront at thecollectionatcl.com for curated furnishings. No external investment, parent company, or subsidiary structure is present; ownership and creative direction are concentrated with the founder. Operating structure, headcount, and revenue are intentionally not publicly disclosed.
