Gold Delta Award 1961 to concrete relief paving by Antoni Gaudí. A reedited version of the relief paving designed by Gaudí for the Batlló House in Barcelona. Made of moulded coloured concrete, the pattern in each tile makes it possible to create three different drawings on the ground depending on how it is laid out. The theme , wich incorporates organic references, does not hide the industrial character of the product – one more author’s most important incursions in this field. The Gold Delta awarded to this product was really an honorary prize.
