44 types of marble, 6 patterns, 25 colour ranges, material wastage reduced close to zero: design inlay work comes into the world. The designs, the nuances and the productive approach of the "Opus" collection by Lithos Design Primes literally break down the classical idea of marble inlay work and its use in the field of decoration for floors and claddings by driving innovation into hitherto unexplored realms. The collection presents a variety of hues, in a series of ready-for-use ensembles that do not forgo the preciousness of antique inlay work yet at the same time speak to the onlooker in a new language, linked to an exceptional mark of design. This is a sequence of 60 cm x 60 cm x 1,8 cm modules, with patterns that can be extended depending on the tastes and requirements of the designer, in wall claddings and floorings. Each module is easy to lay and it comes delivered in a completely finished form. The rendering and added value are the same as for a traditional work of inlay, but with some further unprecedented benefits: the possibility to choose between different patterns whose aesthetical and chromatic format is pre-defined as it has been subject to careful prior assessment, the freedom to be able to apply the design inlay to horizontal or vertical surfaces of any dimension and exceptionally short fit-out times.
