Just for fun, here are some facts about the Joestar house itself!
Aside from some small hand mirrors (which are put away when not in use) and a tall standing mirror in Jonathanās room, there are no mirrors in the house. Yes, this does mean awkward blank spots above the bathroom sinks.
Kakyoinās room used to be Jonathanās, and what is now Jonathanās room was originally his parentsā. All of the original furniture is still there, so although itās a nice room, it looks like... Well, like a room designed for a well-off domestic couple with classical tastes in the 90s, not an unmarried 20-something guy living with 6 housemates who works in retail and barely has enough money to afford groceries. (Admittedly he likes the look of the furniture, though.)
Joseph/Caesar and Jotaroās rooms both have glass sliding doors that open onto a balcony overlooking the pool. Jotaroās room has several posters (including a massive print of the periodic table of elements), a small TV and a large fish tank on the desk, a dog bed for Star Platinum, and a photo of famous marine biologist Rachel Carson in a dolphin-themed frame that was a mirror until he punched the glass out.Ā
Joseph and Caesarās room has walls totally covered in all sorts of posters, wall scrolls, photos, and magazine clippings, and also has a large CD tower and a shelf running all along the walls that displays various figures, Lego sets, and other collectibles. There are also several cardboard boxes full of comic books under Josephās bed.
Josuke and Okuyasuās room is on the first floor, and used to be a library with a frankly really impressive amount of books in it. A few bookcases are still in there, but the rest have been moved to either the office, Jonathanās room, or the attic. Aside from the bookcases, their room contains a small bed, a futon, a dresser, and a laundry hamper. They take turns sleeping in the bed vs. the futon.
The attic is mostly used for storing seasonal items (clothes, Christmas decorations, etc.) and bins full of stuff belonging to George and Holly that the boys never bothered getting rid of, but donāt have any use for. Some of the things in there date back to the late 80s.
There isnāt a basement, but there is a garage, where they keep the washing machine and dryer. They also use it to store tools, gardening supplies, outdoor toys/sports equipment/pool stuff, and groceries that donāt fit in the kitchen (thereās a big shelf unit and a small refrigerator). There isnāt enough room in the garage for cars, so they all stay in the driveway.
The kitchen has several different sets of fridge poetry magnets, which result in some... interesting literature. And no I canāt really deny that they have the Sweet Bro and Hella Jeff fridge magnets tbh. Of course it also has normal stuff like photos, takeout menus, shopping lists, etc.
Thereās an old upright piano in the corner of the dining room that was a gift from George to Holly for their 10th anniversary. Itās a nice piano, but piano maintenance is expensive and not really a priority, so it hasnāt been tuned in several years and would probably sound terrible if played.
There is a fully functional fireplace in the living room, which they do use sometimes in the winter (more for atmosphere than anything, since the house does have central heating). Whether or not this is actually a good idea is... questionable, since the chimney probably hasnāt been cleaned in quite a while. Thereās also a sword above the mantel, which Jonathan is very fond of.
As far as electronics go, there are two TVs in the house: a large HD flatscreen TV in the living room, and a small CRT TV in Jotaroās room. The three computers include Kakyoinās gaming computer in his room, Jonathanās slightly old laptop, and the family desktop in the office. The desktop is old and still uses Windows 7, and runs fairly smoothly thanks to Josuke, but just isnāt up to date enough to run some stuff. An Xbox 360, Wii, and Playstation 3 are hooked up to the TV in the living room, while Jotaroās TV just has a GameCube, and thereās been some talk of possibly pooling money and saving up for a Switch for the household.
