I have always been very interested in architecture, but the type that really interests me, are the buildings that are almost epic in scale. I really love to see the modern marvels of the world and it’s pretty much my life goal to build one.

If you’re anything like me, seeing these buildings in their full glory brings a tear to my eye!
