Eugene H. Krabs and Pearl Krabs' house
3541 Anchor Way is Mr. Krabs' and Pearl Krabs' anchor house (as seen by the address on Mr. Krabs' license). This house is three stories high, with a basement.
Features/Rooms
The basement is a large room. It has a washing machine and dryer, along with a work bench (Wet Painters). In The Slumber Party, the basement is shown with many barrels of root beer. It might be possible that this was a different room since it was not considered a basement. 
On the first floor is the living room; there are many valuable items, pictures, and a vending machine. The first floor is painted white on the walls, since Wet Painters. By the front door is a barrel TV. The kitchen and dining room are all in one room. In the dining room, there is a table, chair, and a window with a curtain.
The second floor to the right side of the house contains Mr. Krabs's bedroom. He sleeps in a hammock and has a bedside shelf. A master bathroom is connected from the bedroom which includes a toilet and a sink with a mirror.
Pearl's bedroom is located on the left side of the house and contains a bed and walls filled with Boyz Who Cry posters.
There is a third floor to the house, though it is unknown what room/rooms are up here. In The Slumber Party, it is revealed that there is a piano somewhere in the house. It may be on this top floor. Also on the third floor is a balcony overlooking the front yard.
