Arc Interiors — Luxury Interior Designer in Nassau County & Long Island, New York

Diana Basily

Diana is a Roslyn-based interior designer known for warm, modern, beautifully balanced spaces. She holds a bachelor's degree in architecture and began her career as a project manager, building a deep foundation in structure, planning, and execution.

Her path widened through floral design, where she later founded her own event studio. Working with nature and organic forms sharpened the eye for texture, composition, and movement that leads her interiors today.
