A wave of creativity inspired by the book Xenology: An Introduction to the Scientific Study of Extraterrestrial Life, Intelligence, and Civilization by Robert A. Freitas Jr.
In this piece, I did my best to recreate the alien megastructures described in the book and bring to life the idea of a Type 4 civilization on the Kardashev scale with artistic liberties I may add (Spoilers:Structures were not properly scaled up properly ). A civilization on this stage is capable of harness the power of many million galaxies.

From the book, the central "Megasphere" in construction will have a total cost of 1300 galactic masses from the construction alone not counting the upkeep.

Then we have the mega ring. With a diameter of 20 light years, the ring provides home the likes of a trillion Earths. Such big is the structure that it needs to have the stars orbit around the ring via magnetic fields.

Then, (and not scaled up) we will be having the big mega ring. Just a 2000 light year structure who needs to have a quasar (that big blue raging star) in the middle for the purpose of the living. The ring has the surface of 130000 Trillion earths

Finally and yet most impressive is the megadisk which apparently is one of the most efficient megastructures when it comes to bang for buck ratio in the intergalactic market. As with the previous structure, is not scaled. Yet, with only needing, 11 Galactic masses for the assembly, it provides a 1000 times the free real estate provided by the Big Megaring.

Finally, we have the Big Megasphere, The last feat of architecture and the best way to tell the rest of the universe how disgustingly rich you are. A 2000 lightyear sphere worth 4000 plus galactic masses. The rest of the intergalactic community will be very angry that you are accelerating the heath death of the Universe but let's be honest, they are all just jelly of your achievements.
