I.Meet the Founder

Irena Viitiuk

Founder & CEO

As founder and principal of IV Atelier, Irena leads every project from the first conversation to the final installation detail — because that level of personal attention is what separates a beautiful space from an unforgettable one.

Her work spans luxury residences, boutique hotels, and high-end commercial environments, all shaped by a single conviction: interiors should do more than look beautiful. They should change how a space feels and how people experience it.

Irena holds a degree from the New York School of Interior Design and approaches every project as a complete spatial composition — balancing architecture, materials, lighting, and proportion to create interiors that are refined, immersive, and built to last. Her perspective on design has been featured in Architectural Digest.

II.Our Approach
01

Vision & Strategy

Every project begins with listening. We study the architecture, understand the life being lived in it, and define the design direction that will shape everything that follows.

02

Design & Development

Concepts become interiors through material studies, space planning, and photorealistic 3D visualization — every detail resolved before a single contractor is called.

03

Execution & Delivery

We coordinate every contractor, supplier, and fabricator — managing the entire process so the finished space matches the vision with precision, on schedule.
