Herbal Hill was originally designed for a refurbishment project in Clerkenwell, London, UK. The original industrial interior of the building was complemented by KAZA floor tiles to convert into a luxury office space. The Herbal Hill tile series consists of a square and a rectangular shape, which can be used separately or in combination, opening up the opportunity for endless layout arrangement options in a range of natural pigmented colors. Tiles are manufactured by applying a mixed technique: first, a dimensional surface is cast, then, after curing, the elevated part of the design is ground and polished in order to expose natural stone chips, while the recessed area within the same element remains smooth. The resulting combination, beyond the poetic meaning of honest materiality, is a next level terrazzo and a pledge to timeless design.
