Edificio Castelar - Rafael de la Hoz Arderius (built 1977-1983) Madrid Projected in 1975 by architect Rafael de La-Hoz Arderius and inaugurated in 1983. At the present time it's a Catalana Occidente's (insurance company) office building. Due to the glass panels the building seems to float above the ground floor made of white stone (Škriljevac stone I think, couldn't find the information). Rafael de la Hoz Arderius was born in Madrid in 1924. He graduated from the School of Architecture in Madrid in 1951 and finished his studies at M.I.T. in the United States.
