Okay, let’s calculate this. Barbara has 10+ years of experience as an architect and designer, which is a solid foundation. Her skills in planning, architecture, and design are in demand. She’s the owner of her own firm, which suggests she’s self-motivated and possibly charging a premium. Location is Oakland, CA, which is a tech hub with a high cost of living. According to the Bureau of Labor Statistics, architects in the Bay Area can earn around $100–$150 per hour. Considering her experience and skills, I’d estimate her hourly rate to be around $125, which is slightly below the average but still competitive.
