  • "K&K was the first studio I approached for design. They shared their ideas and inspired me to come up with new ones. Not only did I learn a lot of useful information, but I also solidified my vision, discarded unnecessary ideas, and cast aside most of my doubts".

    LORA TEREKHOVA

  • "I contacted the studio when I was building my own house. Since I had absolutely no construction experience, the girls suggested how to best transform the space to make it feel like home, and they selected furniture and decor. The house is ready, and I'm very happy with the result!"

    SERGEY BORISOV

  • "I had a very pleasant experience working with K&K. They are responsible and creative designers. The work was completed on time, and their ideas were clearly communicated. Thank you for the pleasant collaboration!"

    DES AIRAN

  • "I've always admired the aesthetics of the interiors created by K&K designers. Besides the aesthetics and professional approach, I'm very pleased with the positive communication. I highly recommend this studio!"

  • Working with them reflects professionalism and commitment to time, as my project (sport club) wasn't simple to do redesign for the space and put all the requirements that I need with perfect design, they have patience to understand the requirements, and above that creativity in the work with simple elegant output. Dealing with them is easy and comfortable. They have sense of humor with professionalism in work, my pleasure working with you K&K
