TESTIMONIALS


Mr. Richards

“Patrick McCarthy was great to work with. He is very knowledgable and creative with his design concepts. I had a general idea in mind of what I wanted, and he made several suggestions that significantly upgraded the look and feel of the final design, without additional cost. Thanks to Patrick, my remodel design is way better that I ever could have anticipated. I would highly recommend McCarthy Design if you are looking to do a remodel or new build.”

Mr. Hannon

“We used Patrick on two projects. We purchased a house and needed floor plans to submit to the county. Patrick worked with our interior designer to get the plans for county review. We were very pleased with our remodel project. We also had an ambitious plan to add a second garage and a funicular (incline elevator) from the new garage to the an upper deck. Patrick performed the conceptual design for the recently completed project. We enjoyed working with Patrick on both projects.”

Ms. Salenger

“Patrick took over my project as designer when I realized that I needed more professional design work than I was getting elsewhere. He designed a lovely small house for me, supported me as I worked to obtain a building permit and has been readily available as I have need his input. I would work with him again in a heart beat!”
