TESTIMONIALS

“I hired Hailey and Bea to design my San Mateo residence. Studio 415 created a beautiful and functional interior solution, and I was so inspired that I decided to rehire them to design my Manhattan apartment. Once again, I found them to be resourceful, detail-oriented, and passionate—the process was educational, but also fun. I love the finished product so much that I am not sure which room I like best!”
