The Port Tower is a (fictional) 143m tall skyscraper and lighthouse designed to protect any coastal urban environment from any ships crashing into it. It was inspired by the NECOM House, the tallest building in Nigeria (and West Africa as a whole) completed in 1979 which also functions as a lighthouse.
There are 20 stories with offices in each (100m) along with the roof and lighthouse deck. I wanted to make an urban lighthouse since that's not really something a lot of people think about, except for maybe in a place with an urban lighthouse.

sorry if the staircase is kinda wonky, it's hard to build stairs in a 2x2 area
