The Project Itemis building is rather complex. There are five floors. Here is a detailed description of each, including the outside and Doctor Luster's building..
Outside: The building is in front of you, to the left, there is a very tall, almost ten feet, metal fence. Past that, if you were to go inside, and go into the backyard, you would see there is a ten foot pool and a hot tub in the back, along with a sandbox and a swing set. The entire building is just cream colored, all the way up, made of plaster and wood and everything a normal building is. Wood, metal, et cetera. It looks like a mansion of sorts. To the right, there is another littler building. Only one floor, above it, it states, "Medical Care" and that belongs to Doctor Luster. Inside of that is where she takes care of the children and has her own private living quarters.
Floor One: This is the main lobby. The main doors are big, oak, and have exquisite markings all down them with large silver handles. The carpets are burgundy, and the walls are creamy colored and look very expensive. You can hear classical music playing from the speakers on the ceiling. It looks like a hotel lobby almost. In the center, there is a little place with two couches, able to fit about three people per couch, and two little sitting chairs, with a large glass coffee table between them all. The lighting overhead is a very large chandelier with many little bulbs that seem to light up the entire room. There are a few windows to the left, able to look out upon the side yard of the place. There is a door leading to the outside between the two windows. Along the back wall, there is a door that leads into Professor Thorn's laboratory, but that is behind the main desk. To the right, there is one other door that leads to Professor Thorn, and Guro's living quarters. There is a little section in the back, that leads to a staircase, and next to that, is an elevator.
Floor Two: Once you reach the second floor, you see the design of the first floor, it's always the same in this building. The floor is different this time, there is a tiled floor, burgundy of course, but still tile, and creamy walls. There is a large cafeteria within this, created with fresh food, free of charge, and a few porcelain tables with nice metal chairs. There are unlimited plates and drinks and you may get whatever you'd like here, free of charge. No one seems to be here though, just take and eat.
Floor Three: This floor includes each of the bedrooms. There is just a large hallway with many rooms, much like a hotel. The rooms aren't numbered, but you can tell what each room leads to by the markings on the door. These rooms are owned by the guardians of these children. There are many rooms on this floor, each designed special, with everything a person would need, except a kitchen. Each room is installed with two bedrooms, a bathroom, a telephone, and living quarters.
Floor Four: Floor of the animals. Well, semi-animals. Once you walk past those elevator doors, or walk into the room via stairs, you'll see many cages. These cages are quite large, and inside, contain many different what look like to be animals. These animals are Professor Thorn's other, mini project. He uses this floor as a holding place for his other projects. Just many cages with animals inside.
Floor Five: No one really is allowed on the fifth floor, for it is used for storage. Extra beds, unopened toilets, bedding, everything that is needed. It's mostly the attic of the P.I. Building, but can't be called an attic because of it's size. xD
