101 Dalmatian Street, the titular location of the series of the same name, is a townhouse in Camden Town at which the Dalmatian family reside. As mentioned in bibles for the series, the house was purchased by Dodie McDot for his Dalmatian Delilah and her puppies before he left them to live on an island.
101 is equipped with several machines (invented by Dylan) to help the Dalmatians with their everyday tasks. Throughout the house are small compartments in the walls in which the puppies (or their toys) sometimes hide. There is also small elevator in the house, allowing easier access/travel across the house's three floors (plus its basement and attic).
The outside of 101 stands out among other buildings on Dalmatian Street, as it is decorated with paint splats (many of which represent Dalmatian spots), umbrellas, and balloons. The front door of the colorful house can be opened (and locked) via a paw-printing scanner that is designed to only let the Dalmatians enter.
First floor[]
Just behind 101's front door is a hallway and stairs to the second floor. Adorning the walls are photos of the Dalmatians (including one of Pongo and Perdita), as well as the Dalmatians' family portrait. Below the stairs is a door that leads to stairs to the basement.
A doorway to the left of the stairs leads to the living room, which features a blue couch, a yellow chair, a treadmill, and several squeaky toys and other objects. Past that doorway is an entrance to the dining room, which holds the Kibble Pump and a long, short table for the Dalmatians to eat their meals at. A kitchen can be accessed through either the end of the main hallway or the dining room. This room is mainly occupied by Dylan, who washes the Dalmatians' bowls in the sink. There is also a washing machine here, which is used as a raffle for the puppies in "All Fired Up."
Second floor[]
On the second floor, there is a closet just in front of the stairs that is filled with chew toys. This floor also includes the Dalmatian puppies' bedroom, Delilah and Doug's bedroom, a guest bathroom (the toilet of which the Dalmatians use as a "drinking bowl," as mentioned in "Dog's Best Friend"), and a quarantine room (predominantly seen in "Fear Window").
Third floor[]
The third floor of 101 features the main bathroom, which holds the Toothbrusher and a bath. The house's attic can also be accessed at the end of the hallway on this floor.
Basement[]
The basement can be accessed either by a door beneath the stairs on the first floor or the house's elevator. The basement is used as a quarantine area for flea-infested puppies in "Flea-Mageddon" and as the venue for Triple D's birthday party in "It's My Party."
Attic[]
Above the third floor is the attic, where various keepsake objects are stored. This includes props from the original One Hundred and Dalmatians film, as well as a painting of the Prince of Dalmatia.
Roof[]
The roof can be accessed through a hatch in the attic.
Backyard[]
The backyard of 101 Dalmatian Street, which is accessed through a door in the kitchen, features a trampoline, a stage-like platform, and Dylan's treehouse. There are windows in the fences of the backyard for the Dalmatians to interact with their neighbors.
