Bobby started as a young designer in Auckland, brimming with creative ambition. But after witnessing too many beautiful designs die on paper - crushed by costs, confusion, or poor execution - he realized something profound: "Design without delivery is just a shelved dream."
Over 25 years, he has led hundreds of residential projects across New Zealand, bridging the gap between architecture and development strategy. His work now centers on empowering clients with knowledge - showing them how to build smarter, safer, and stronger. Bobby’s approach blends architectural insight with business clarity. Through Mercury Alliance, he and his team champion a culture of collaboration where architects, engineers, planners and surveyors act as one unit - protecting the client’s vision from the very first sketch to the final brick.
