our testimonials

"Studio21 was easy to communicate with and we always got quick responses to calls, texts and emails. I’ll never forget the day we walked into their conference room and up on the screen was an image of a BEAUTIFUL home, and I said “that’s the kind of home I want” and their response was “this is your home”. It truly took my breath away, as they really understood us and made our dream a reality."

"We had the pleasure of working with Bill when we built our first home. What we thought would be a stressful and daunting process was an absolutely pleasurable experience. They listened to us with great attention and did not miss any details that we wanted included. It was amazing to see how they pulled our idea of an ideal home from our minds and conceptually put them on drawings."

"Our project was a 1000 ft. addition, adding a primary suite, large family room, and a basement with 9ft ceilings. Our addition is seamless and we still receive compliments two years later on how beautiful our addition looks. Our family enjoys being together in our new large rooms. Entertaining is functional and fun and possible! I highly recommend Studio21 Architects for design and/or build services."
