About Us

Respected accredited designer Diane Ernjakovic is the Principal Designer behind One Three Design Inc.

Diane has always had a realistic and honest approach to the design and construction process. After graduating from Sheridan College with High Honors in Interior Design, Diane worked in the field of retail and commercial design for nearly a decade completing projects ranging in 5,000-50,000 sqft. Diane formed One Three Design Inc. with her former partner and has since then taken over the reins on her own. Diane has also taught part time in the Sheridan College Interior Decorating Diploma program.

In a shift to more residential projects, she has enjoyed the personal connection to homeowners and the joy it brings to both her and the clients. Diane has an affinity towards bright, clean design with attention to details and a subtle feminine touch.

As a mother of two young girls, entrepreneur, charity supporter, mentor and organization junkie, Diane is a believer that there is always a way to make things happen.

“Good design will have you never wanting to leave”
