We recently had the pleasure of working with Onik to convert our pool house into an ADU, and the experience exceeded our expectations.From the start, Onik was professional, knowledgeable, and easy to communicate with. He helped guide us through the entire process, from planning and permits to construction, making what could have been a complicated project feel smooth and manageable. His attention to detail and commitment to quality were clear in every phase of the work.The finished ADU turned out beautifully. The space is functional, thoughtfully designed, and blends seamlessly with the rest of our property. Onik and his team were reliable, respectful of our home, and consistently kept the project moving forward on schedule.If you’re considering converting a space into an ADU or tackling a similar renovation, we would absolutely recommend Onik. His expertise, transparency, and craftsmanship made the whole process a great experience.
