Work done from 1997 until 2001 - Almost all of the windows were the same, of the double crystal type, with different demands in terms of security and protection depending on the floor of the building, in order to follow the regulations of the Protection of the Patrimony Office. The windows had to be rebuilt according to the original model. The profiles were kept as narrow as possible.

Total volume of the budget: 2,500 windows for the Ministry of Finances and 800 windows for the annexed Post building, for a total of 6 million Euros. The price included: the dismantling of the previous windows, planning, fabrication and placing of the new windows.
