Poseidon's Cabin is a long, low building with windows facing the ocean, and looking like it's made of rough sea stone, with pieces of coral at the end of the cabin and a seashell and a trident over the door. There is always a sea breeze blowing through it. Inside: walls made of abalone with rows of neat bunks, and a salt water fountain. There is also a sort of mobile of hippocampi.

Hades' Cabin made of solid obsidian walls, a skull hanging over the door and with torches that burned green fire 24/7. The walls are that same solid obsidian, shimmering with an almost Underworld-ly texture. Occassionally the souls of the dead could be seen shimmering in these walls. There is even a passage, a part of the cabin which would allow the residents to travel to the Underworld without exhausting themselves using shadow travel.

Hera's Cabin is a marble, formal-looking building, graceful with slim columns anddesigns of peacock feathers and pomegranates. It is done in a similar way to Zeus' cabin. Inside: like a temple with a large statue of Hera in the center. There are no furniture inside due to no one will ever stay in that cabin and is honorary (Hera is the goddess of marriage and "doesn't run around having affairs with mortals. That is her husband's job.").

Athena's Cabin is a gray building with silver curtains and a design of an owl over the door. Inside: most of the space is devoted to maps, desks and various projects, with all the bunks shoved together against one wall, "as if sleep was not important".

Hermes' Cabin has peeling brown paint and a caduceus over the door. It is probably in such bad shape because it was so over-populated. Once more demigods started getting claimed and the minor gods' cabins were built, space conditions improved. However, the cabin still is a fun place to hang out.

Dionysus' Cabin has lattice wood walls with grapevines hanging in the doorway and twisting around the wooden walls. It is not unusual for grapes to be picked from the walls and eaten by campers. Inside: The inside walls look like the outside ones, with the exception that they hold bottles of wine. However, touch these at your own risk - they are Dionysus' private stock. The Interior walls are mostly painted purple as well.

Ares' Cabin is inexpertly painted red and has a large boar's head over the door with barbed wire on the roof. a small wall of sandbags line the outside of the cabin creating a makeshift wall much like you might find on a battlefield.
Inside: Inside the Ares cabin it looks like it could be straight out of a war zone. The sheets in the beds are camouflage. Mounted on the walls are all different sorts of weapons like spears and swords maces and what not very medieval, and there are even some random bloodstains from little fights on the floor. But watch your step if you don't know where your walking you might step on a landmine.

Aphrodite's Cabin is a wooden cabin with a painted blue roof, checkerboard floors, and smells heavily of designer perfume. Piper describes it as "a giant Barbie house where supermodels go to die." Inside, it is described as a life-size dollhouse with pink walls and white window trim. The lace curtains are pastel blue and green which matched the sheets and feather comforters on all the beds. The guys had one row of bunks separated by a curtain, but their section of the cabin was just as neat and orderly as the girls'. The cabin is always clean except for under the beds, which had chocolate wrappers, love notes, and other things under them. Every camper had a wooden camp chest at the foot of their bunk with their name painted on it. The only other bit of individualism was how the campers had decorated their private bunk spaces. Each had slightly different pictures tacked up of whatever celebrities they thought were hot. A few had personal photos, too, but most were actors or singers.

Hephaestus' Cabin looks like a small factory, with brick walls and smokestacks like the forges and lots of gears around the entrance. Inside: Leo describes the folded steel bunks against the walls to be like "high-tech Murphy beds". Each bed has a digital control panel, blinking LED lights, glowing gems, and interlocking gears. A fire pole comes down from the second floor. A circular staircase lead down into some kind of basement. The walls are lined with every kind of power tool imaginable, and a huge assortment of weaponry. A workbench overflows with scrap metal, screws, bolts, washers, nails, rivets, and a million other machine parts.

Apollo's Cabin seems to be made of solid gold and made to glow during the daytime - it's hard to tell if the gold is reflecting light or generating it. It is unknown what the cabin looks like from the inside.

Artemis' Cabin is an all silver building with silver curtains, similar to the outfit of the Hunters. It also glows silver during night time as if reflecting the moon, but looks like a normal cabin in the day. Because Artemis is a virgin goddess, she doesn't have children of her own and the cabin is honorary; however it is used by the Hunters when they visit camp.

Demeter's Cabin is covered in flowers and tomato plants grow on the walls and doorway. It has a real grass roof. There are window boxes under the windows with small gardens growing in them. There is a small tool shed in the back of the cabin where gardening tools are kept as well as a small greenhouse attached to the side.
Inside: Inside everything looks very organic. On each bed etched into the wood are flowers and plants beautifully illustrated. The inside of the cabin always smells like nature at it's best.

Hecate's Cabin looks normal but is built from blocks of stone with magic inscriptions written on them. If the blocks are dropped or fall off, they could explode or turn anyone within half a mile radius into trees.
