on•entropy is a marble design and makers studio founded in 2013 by sisters Niki and Zoe Moskofoglou. With deep roots in the Greek marble tradition and an eye towards global contemporary design, we create furnishings, lighting, and sculptural objects that inhabit the space between design, art, and architecture.

Marble has been part of our lives since childhood—woven into our family’s history for over five decades. This lifelong relationship with the material gives us not only access to rare and exceptional Greek marbles, but also an intuitive understanding of its nature—strong but fragile, rigid but plastic, heavy but ethereal with a timeless beauty.

At on•entropy, our guiding philosophy is simple: design for the mind and the senses.

We believe that marble should not only be seen, but felt. With craftsmanship at heart, every object we finely carve in our studio in Athens, GR is designed to evoke atmosphere, texture, temperature—even scent. It is our way of honoring a material that has evolved over millennia, and inviting others into a deeply sensory experience.
