124 Conch Street is the address of the pineapple house where SpongeBob SquarePants and his pets, Gary and his scallop Shelley, live in. 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 sea, as seen in the TV special "Truth or Square."
It also has an outdoor tap where a hose can be attached, as seen in "Unreal Estate."
On the first floor, his house features a living room, a coat closet, a room with a fireplace, and a kitchen. The living room features an inflatable sofa and a diving helmet TV. There is a small table with a phone shaped like a conch shell, called a shellphone. One of the corners in the living room contains his desk, as seen in "Procrastination."
There are two fishing hook ornaments, one regular and one shaped like a fish, on the bamboo wallpaper. In addition, pictures of SpongeBob's friends, family, and his favorite superheroes are on the wall along with a porthole window. He also has a bookshelf.
The kitchen contains a fridge, a stove, sink, a cupboard, and a table, and other typical kitchen tools. Gary's food bowl can also be found here, though sometimes it is seen in SpongeBob's bedroom. A green staircase is located outside of the kitchen.
SpongeBob's bathroom, a long hallway, and the bottom of his library/study are on the second floor. Another long hallway, the top of his library/study. and SpongeBob's bedroom are on the third floor. The staircase leads up to a long hallway.
The hallway has doors leading to his bedroom and bathroom, as well as an additional staircase that leads to his library. In his bedroom, there is an alarm clock that is a loud foghorn. He has a bed with three mattresses, above which contains a diving board.
He has a giant calendar on the wall and a porthole window looking towards Squidward's house. From SpongeBob's bedroom, there is another door leading to his library. In the library/study, the largest room in the house, there is a chair chained to the ceiling by a fishing hook, as well as a huge pipe organ, and SpongeBob's other closet.
There is a small garage in the back of the house and two windows in the front. The garage is first seen in the episode "Reef Blower."
Out back of the house, the backyard is closed in by a square of flowers, much like the ones seen in the sky, but in The SpongeBob SquarePants Movie video game (PS2/PC), SpongeBob's backyard has instead boards, not flowers. On the first floor, his house features a living room, coat closet, trophy closet, kitchen, laundry room and a kitchen pantry. The living room features an inflatable sofa, a regular chair with a life ring as a seat, and a diving helmet-shaped TV, and a small table with a phone shaped like a conch shell called a shellphone.
There are decorations such as a fishing lure above the sofa, a photo of Gary near the kitchen door, and on the left a fishing hook wall ornament, above a small table. On the small table is a potted coral plant. SpongeBob spends a lot of time here. The living room features bamboo wallpaper, two fishing hook ornaments and various pictures framed on the wall. The kitchen contains a window, a fridge, a stove, sink, a cupboard, a table, and other typical kitchen tools. Gary's food bowl can also be found here.
There is a set of stairs on the left that twists around the home and stops at a safe door behind the chute entrance to the second floor. In some episodes, there is a hallway behind the door.
SpongeBob's bathroom is found on the second floor. The hallway contains doors leading to his library, bathroom, and gallery, as well as an additional staircase that leads to his bedroom.
His bathroom contains a square-shaped toilet, a shower/bathtub, a sink, wringer, etc. as well as a porthole window that looks out onto Conch Street. His bathtub is decorated with a bamboo curtain.
The library is the largest room in the house and occupies both the second and third stories. It contains books such as Moby Dick, The Godfather, and Silence of the Clams, as well as various comic books and SpongeBob's Work Diary. The library also contains a reading chair chained to the ceiling by a fishing hook, a huge pipe organ, a fireplace, a porthole window, and a spare closet. There is also an entrance chute coming from SpongeBob's room, first seen in "Boating School."
The staircase to the third floor is also green-colored and is found next to the library. SpongeBob's bedroom is found on the third floor, along with a hallway. SpongeBob's bedroom features a foghorn that serves as an alarm clock, and a diving board above his bed (which has three mattresses). The bedroom also contains a porthole window from which the inside of Squidward's House can be seen. The fifth season episode "Night Light" shows that there is another bathroom attached to the bedroom.
SpongeBob's third floor contains an escape hatch to the roof. Most of the time, SpongeBob climbs onto his roof to avoid various types of danger, although he also runs up his wall to the roof in, "Best Day Ever" where Gary is revealed to be at the top of. The roof contains one unfurnished room with no ceiling, and the wall is made out of the crown of the pineapple. Characters commonly climbed to the roof in the first 4 seasons, but it has barely ever been seen since.
"Home Sweet Rubble" - Due to being rotten, SpongeBob's house disintegrated, but was replaced by each of something of his friends' favorite things, but was soon replaced again by a fully furnished pineapple in a can.
In "Squid Baby," it was mentioned by SpongeBob that his house contains an attic.
In the episode "Truth or Square," it shows that a sailor was painting a bowl of fruit in the sea, then a pineapple falls out of the bowl and lands near Squidward's house; a door and windows suddenly appear.
It is impossible for a pineapple to be underwater because pineapples float. The furniture may be what makes it stay on the ground. In some episodes, it's made of wood.
The staircase inside SpongeBob's house is sometimes on the left side, and sometimes it's on the right side, or it could be on both sides.
In the episode "I'm with Stupid," after SpongeBob crashed his house, Marty said "That's unhealthy," after Janet said, "He lives in a fruit?" This is because of their stupidity.
In "One Krab's Trash," his bedroom is on the first floor, while it is usually on the third floor. This may have had to be done because it would be impossible for Mr. Krabs to scare SpongeBob through the window on the third floor.
There is a game on TLC.com in which players have to match coupons to the correct item and one of the coupons has the pineapple house on it.
In earlier episodes, the blanket on SpongeBob's bed was blue. But in later episodes, it is purple.
Although, he may have just bought the purple one.
In the episode "Help Wanted," when the first time SpongeBob's house was seen, there was only one window on the top left, but in future episodes, he has two windows.
Sometimes, the garage at the back of SpongeBob's house is directly in the center, and sometimes, more off to the side. Sometimes, there's a back door in the center.
His house is sometimes shown as an actual pineapple and other times, it appears to be made of wood.
When you compare the outside and inside of SpongeBob's house, his house looks a lot bigger on the inside.
In the episode "Help Wanted," SpongeBob's bed is on the right side of the room, but in other episodes, his bed is on the left side.
If a straw is stuck in the side in the house, one could use it to drink the pineapple juice from it. This is demonstrated by nematodes in the episode "Home Sweet Pineapple."
The only way SpongeBob's house is able to stay under water may be due to the stems keeping the house stationary as revealed in "Home Sweet Pineapple."
In the episode "Boating School," SpongeBob's library is located right where the staircase should be. Yet, in later episodes, the true passageway to SpongeBob's library is unknown though many instances show that it is located just before the stairs, supposedly if SpongeBob has a hallway connecting the stairs and the library.
In the episode "Suds," SpongeBob's house is frozen because he left the refrigerator open for too long.
