About TRIOSee the List
Welcome to TRIO

The Creative Business Partner for Builders & Developers

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, multifamily apartments, and we offer a comprehensive studio for everything related to interior architecture and merchandising. Let’s connect and discuss how we can help with your project.

Who We Are

AN UNPRECEDENTED, AWARD-WINNING COLLABORATION – The TRIO Collection™ represents an industry-changing partnership between designer, builder, and architect offering unique style, sophistication, and choice in a custom home. The partnership between TRIO, Joyce Homes, and KGA Studio Architects produced stunning results. SEE THE COLLECTION

Have a cause we might be able to help with? Lets us know.


Watch our documentary on the Exceptional Education Outreach (EEO) program. The EEO is a public, non-profit special education and literacy project operating in the Bahamian Family Islands. TRIO built a new school for this deserving organization and made it a focal point of the TRIO 3% Initiative – the story was so good we had it documented.
