around 7 floors with around average height for the floors be made of rainbow bricks 2 rooms per floor and yes definitley npcs and image 2 is most like it
Here is a blueprint:
First, we need to select a full theme for your mansion. For instance, the mansion design you chose was in the "vortex" style looking like the vortex pillar and stuff like that. All I can think of with the gradiant rainbow is a "gamer mouse" style...
So, we need to use something like that like graphite. But since there is no graphite in Terraria, we have to use the closest thing, graNITE! Since it doesn't look cool, I'd reccomend painting it black. For the rainbow theme, I'd also recommend using some crystal blocks. Well, let's start!
At first, let's try the 7 floors first:
Here, we see a simple 7 floors... But we should make a nice corridor and thicken the walls:
. Let's add a floor and roof to this base:
As you see, I also made some curves at the bottom to make it less robotic. Well, we made the base, but no one can get inside it! We need some doors and platforms! And what is a stylish base without an epic crystal inside?
As you see, I made a special addition in the 6th floor.
Now, we've got purple for crystal blocks, but where are the rainbow blocks? No worries, we got your back! :
"What about granite" I hear you ask. We should add those along with some more crystal!
(purple for crystal blocks, blue for granite, brown for platforms and doors, black for undefined blocks)
Let's add some glass! But for that, we won't add actual glass, but echo blocks! (I'll explain why) Now, you must really be wondering why would we do that, right? Well, we were going to put an echo station!
Now, the full reason for using echo blocks here is for the glass to look more transparent.
So, the place looks very plain and simple. We gotta have some more detail: Now it looks better! Also in the 4th floor, we see tall gates. It looks nice so I decided to add them! Well, no house wouldn't have walls, right? Let me show you a map of walls: As you see, I made a little room inside the floors. The reason I did that was because I was going to use it to put an electrical circuit inside. But before we get into that, we gotta come close and make an interesting choice of light source. First, we need gemspark blocks. 2 of each color will suffice. Also, don't forget to bring your echo coating! We'll need that! (there is an 8th pad at the right tip of the room) You need to place them in this order. Paint them in echo coating and actuate them. Since you wired them, you probably also caused them to be deactivated. Let them stay that way. Now, remove the wires and actuators. The gray thing is a boulder statue with teal pressure pads in front. Wire them in this way:
