Interesting roof lines

I wish I could tell you what these four building in the Ortigas Center are, but I can only identify the two in the middle. The one with the pointy roof is Richmonde Hotel. The ziggurat overhung with plants is one of my two favorite buildings in the area, the headquarters of San Miguel Corporation. Built in 1976, it was designed by the brothers Manuel, Jose and Francisco "Bobby" Mañosa. San Miguel is one of the largest food, beverage and packing companies in the Philippines but is probably best known for its beer.
