About Me

Belina Costa began her career in Interior Design over 15 years ago. After spending years in both the residential and commercial arenas, managing high end showrooms, working as principal designer in her own design firm and working with the Real Estate community, she honed in on her passion for design to intentionally create well thought out designs for each unique individual and space.

Belina holds a masters in architecture and a bachelor of science in interior design. Belina is the founder of HARMONYbydesign. She is an expert in her field, and truly loves what she does. She is the author of numerous design articles and has spoken at many events on motivation as well as celebrating ones uniqueness and having that reflect in their own environments. She believes in designing with a “human touch” which encourages a sense of joy and balance in every project. Her personal journey has led her to examine more in depth the vital connection of architecture and well-being. "The physical spaces you inhabit daily have a direct impact on your body, mind and soul. When things in your environment are in harmony, so are you, helping you attract all of your intentions for well-being, abundance and so much more!"
