Project made from a limited number of prefabricated pieces, with special interest being in the cover piece, patent number 353168, which attempts to mix in an only piece the proper characteristics of a Trapezoid Piece and the HUECOSA Sigma piece. A piece that would allow us to get summit light and to get to covering 25 meter free lights.
None of the solutions was accomplished, remaining only at the theoretical level. From these years onwards, Fisac’s investigations started to orientate towards flexible casings. OF this kind are patents like the 382096 of 1970. All this will open the door for his last patent, “Poured Architecture”, that although in a stage of continuous development, will be the first of the integral pre-fabrication patents that Fisac actually develops outside of the paper plans.
