Strata was designed by CTRLZAK for the Urbi et Orbi Medius Terra collection in 2024.

It is inspired by natural geological formations (stratification). It captures sedimentation, erosion, and volcanic activity through stacked layers, symbolizing the passage of time. The design is inspired by the Mediterranean region’s diverse landscapes and geological phenomena. The overlapping layers of mineral compositions represent the geological history of the Mediterranean and our planet. Strata encourages reflection on our perception of time through geology and the natural world.

The Strata suspension lamp is designed for indoor use and features a unique finish that can only be achieved with concrete as a base material. Each piece is unique and different, holding onto the design concept. It was a construction challenge for us, and we loved it from the first moment when it was still an idea. We developed special production techniques to approach such a natural appearance.

One or more pieces suspended above a dining table or a living room table illuminate the space discreetly or dynamically like spotlights.
Ideal for commercial or residential spaces, it is available in a cold and warm color palette.

This concrete suspension lamp is produced through our company’s Zero Waste Project developed over the past 3 years, with a recycling rate of 20%. The concrete used in production is formulated with only 10% cement.

Every piece may exhibit color variations on its surface, as well as among other pieces of the same product or sample products. The concrete surface exhibits surface voids that are caused by the air. This is a natural property of concrete.
