Sandra Costa Design Group operates out of Beverly Hills but pulls work from across the LA basin, including at least one Santa Monica oceanfront condo mentioned in recent reviews. Their 4.5-star Houzz rating across 34 reviews suggests consistent execution, though I'd note the evidence here is thin—one visible testimonial praising thoroughness and talent, plus a single project photo showing kitchen pendant lighting. That's not enough to judge the full range of their bathroom, kitchen, and flooring capabilities, but the social presence (Facebook, LinkedIn, Twitter, Houzz) indicates they're actively maintaining visibility.
The Beverly Hills address and design-build focus tell me this is likely a higher-end firm working with architects and designers on polished residential interiors. If you're in Santa Barbara and considering them, understand you're hiring someone who'll need to coordinate from 90 miles south—doable for the right project, but factor in travel logistics and whether local subcontractor relationships matter to you. I'd want to see more completed work samples and talk through their process for managing jobs outside their immediate service area before committing. Solid rating, but verify the portfolio matches your scope and budget expectations.
