What if there was an architecture firm that asked a lot of “what if” questions to help you create great spaces? Good news, there is. It’s us. Curiosity guides us through every project. It’s how we get to know you and your needs. It’s how we think and rethink through solutions. And it’s how we work with you until we’ve designed a space that works for you. We’re ThenDesign Architecture (TDA). We specialize in architecture, planning, and interior design, and are recipients of the NorthCoast 99, Plain Dealer’s Top Workplaces, Weatherhead 100, the Northeast Ohio Success, and the Fast Track 50 Awards.
