leopoldo calvo-sotelo was a short prime minister but he had enough time to enable more rooms on the third floor (he had eight children) and also a music room to install a piano. felipe gonzález arrived in 1982 and cultivated a small orchard of bonsais although the major work he did in the complex was the construction of an underground bunker. in his mind, there was a memory of the coup d'état attempt of february 23, 1981. he also built a new building close to the presidential residence to carry out the council of ministers, releasing in this way the main building of some work, and dedicating it more to the private residence of the prime minister.
