I am a builder who has done multiple homes in Newport Beach. I have used a different architect but was constantly disappointed. I asked other builders and city officials for references. Bill’s name constantly came up. I interviewed him and he took me to multiple job sites. I was very impressed. When it came to the design - wow! What a difference an architect makes. His design was incredible and I couldn’t have been happier. Correspondingly, I am accustomed to making a number of changes out in the field once I can physically see the plans come to fruition. I have never had a project have so few changes because Bill thought of virtually everything and incorporated them seamlessly into his layout and design. And as a builder time is unbelievably important to me. I want to get plans through the city as fast as possible. Bill’s extensive knowledge along with his relationship with city officials is unmatched and he was able to get the plans through incredibly quickly with minimal corrections. I am so happy with her service that I will never go back and continue to use Bill on all future projects. I have attached a picture of his rendering and will repost in several months photos of the actual project when completed.Read More

Bill Guidero is wonderful to work with. He is experienced, capable, draws very detailed plans and is collaborative with design ideas. He also has a great disposition in working with you and your clients, in a no nonsense, no pressure kind of way. We thoroughly enjoyed him in this project!Read More

We hired Bill Guidero to design our custom home after meeting with a variety of architects. From the first time we met him, we found Bill to be warm, personable, knowledgeable, creative, user friendly, and most importantly, someone who was willing to really listen to what we wanted. After visiting some of his projects and speaking with his former clients, we found his work and reputation to be impeccable. Bill was a delight to work with. He designed exactly what we wanted in our dream home and enhanced our vision with a number of helpful and creative suggestions. He also made the process of city and homeowner association approval a smooth one, which is no easy feat! Bill offered a large number of referrals to contractors with whom he had successfully partnered, and it resulted in our finding a perfect contractor match for our project. Despite his part of the job being completed, Bill remained involved throughout the construction, visiting the site to monitor progress and answering any questions that came up along the way. Our new home is gorgeous, and is everything we wanted and more. We couldn’t be more pleased, and we have Bill to thank for making our dream and vision a happy reality. Don’t hesitate to hire Bill - he is the best!Read More

Bill Guidero is the bomb! He listened when needed and provided ideas when we were lacking. He was always available when questions arose and was super helpful in problem solving during the building process. His design on paper looked great and now that we're living in our home we are thrilled with the spaces and the light. On top of all this Bill is fun and a pleasure to work with. We highly recommend him!Read More

I was brought in on one of Bill's new construction projects to do the interior design by his client. I've worked with a number of architects over the years, and Bill by far is one of the easiest-going and professional ones to date. He is pleasant to work with, clearly knows his stuff and most importantly, the clients' were thrilled with his work. Their project is under construction right now and they have been most pleased with everyone on their project team.Read More
