I headed over to Lotte Tower on Saturday January 9th 2016 to see the progress up close and in person. It has really grown. Almost done. Here are some progress pictures I personally snapped.
A pic looking out the window of them lifting supplies up to the top.
This is on the south side of the building.
Facing south east.
This might as well be called Lotte Square as the two gold build on the left are called Lotte Mart and behind me is Lotte World, which is a Disneyland styled theme park.
