The Casa Zen collection of design doors is the successful result of the cooperation between artist Elio Garis and Bertolotto. Every door is unique, like a work of art. All models from this collection are decorated with sand sculptures, which the artist coloured and moulded by hand. Their design is inspired by traditional and natural Japanese stone gardens, a true synthesis between simplicity and harmony. The collection includes seven models with different shapes and colours, but always up with the latest trends, and doors whose glass panes imitate the recurring lines and styles in the collection. Casa Zen glasses can also be fitted on other doors from Bertolotto collections.
