SpongeBob's house, address 124 Conch Street is the home of SpongeBob SquarePants and Gary the Snail. The house is three stories high and fully furnished. The pineapple itself originates from land, when it fell off of a ship navigating above the ocean, as seen in the special "Truth or Square."
Exterior and Interior
The exterior contains a floral pattern along the entire bottom of the house, and has a front door and two (sometimes three) windows. At the top in the leaves of the pineapple, is a hatch. The house also has a garage in the back.
The interior of the house features a living room and a kitchen. The amount of levels in the house is seemingly unclear, but appears to have 3 levels including a massive library as well. A door leads straight from SpongeBob's bedroom to his library.
