Uncommonly creative. Unwaveringly trusted. Unabashedly fun. While this is how Helen Koss Interiors describes its approach to interior design, there is no doubt that every client that has worked with this innovative studio would use the same words.

Helen Koss Interiors was founded in 2009 by Helen Koss herself while she was living in Tel Aviv, Israel. A few years later, in 2013 to be exact, Koss made the decision to move the business to Sofia, Bulgaria, where she currently resides and operates the award-winning studio. Today, Helen Koss Interiors is a highly regarded interior design consultancy that is best known for its professionalism, indescribable aesthetic and inspiring approach to capturing the heart and soul of every project.

In the almost ten years of operating in Sofia, Koss has developed her business impressively, having grown a portfolio of interior architecture and design work covering commercial, hospitality, residential and multi-family spaces. Helping her achieve this is a team that includes designers and creative talent who are firmly committed to the success of every project.

Together, the team at Helen Koss Interiors have mastered the precise art of combining design innovation with creative ingenuity. In producing their outstanding work, Koss and her team draw inspiration from sources as diverse as fashion, nature, film, art and global culture.

While customer satisfaction is what Helen Koss Interiors prioritizes in everything they do, internally, the focus is always to have fun, collaborate and ensure growth. “This,” according to Koss, “is what enables us to produce quality work. I strongly believe that when a team is happy and inspired, their outputs will reflect their inner joy”.

Believing that we should never stop learning and exploring, everyone at Helen Koss Interiors is always up to speed with the latest trends and technological developments. This deep sense of purpose in their work is the reason Helen Koss Interiors has come to be known as a studio that pushes the boundaries of interior design in the best possible way.

According to Koss, “At Helen Koss Interiors, we believe that every project has a unique soul, just as distinctive as each client, and it’s our job to evoke that personality through space planning, material selection, furniture and décor”. This unique and intuitive approach to their work is one of the reasons that Luxury Lifestyle Awards awarded Helen Koss Interiors the impressive title of Best Luxury Interior Design Studio in Bulgaria for 2021.

Koss credits her diverse heritage as the reason she’s fearlessly able to take bold risks with her projects. Almost nothing is off limits when it comes to her designs. It is no surprise then that the agency has won several other renowned European awards and has been nominated to many local and international awards and competitions. In 2021, Helen Koss Interiors has won the Big See Interior Design Award as well as the Build Design and Build award. In 2020, the studio won a bronze award at the Novum Design awards and obtained recognition at the German Design awards. For more about Helen Koss Interiors, visit: https://www.helenkoss.com/.
