The invention of the structural materials of steel and reinforced concrete in the nineteenth century allowed modernist architecture to develop in the twentieth century. Unlike classical age buildings that required massive load-bearing masonry walls, walls could be hung like curtains on the structural frame fabricated from those materials. This revolutionized architecture as modernist architects realized the freedom they now had to develop previously inconceivable forms. And the structural frame itself could be part of the design. This hotel in the neighborhood of the airport in Ho Chi MInh City is a clear expression of structure. The columns, intersecting beams, and floor slabs are the prime factor in the design, and simple screens and walls are added to the frame to accommodate the room functions. Add a bit of color and you have an interesting modernist composition.
