Welcome to TRIO

The Creative Business Partner for Builders & Developers

Whether introducing ourselves for the first time or you know us well, we want to take the opportunity to share some information that includes TRIO’s past, present, and future.

In 1999 TRIO Environments began when Angela Harris saw the need for a design firm that not only conceptualized beautiful interiors, but also understood how sales and marketing could work in tandem with great design. At that time there were only a few firms concentrating on market-driven design, and TRIO thought it could be done better— hitting targeted markets at a lower cost, in a shorter time period, and with better quality merchandise. WE WERE RIGHT!

Today we move forward as TRIO, in a bolder, bigger way. We collaborate on all aspects of master planned communities; model homes, clubhouses, sales centers, commercial and hospitality projects, active adult living, and multifamily communities. We also offer a comprehensive studio for everything related to interior architecture, design, and merchandising. Let’s connect and discuss how we can help with your project.
