The Big House is a large, sky-blue house which serves as the main administrative building at Camp Half-Blood.
The Big House has been a part of Camp Half-Blood for a long time. It has held the Oracle's body ever since she died (before Rachel Elizabeth Dare was made the Oracle at the end of The Last Olympian). It was painted red during the 1980s' through the early 1990s', but has since been painted baby-blue with a white trim. It also has a bronze eagle weather vane with wind chimes that turn into dryads as they spin.
Mr. D, Chiron, and the other Camp Half-Blood staff members meet with the cabin counselors there. Also, it serves its purpose as the camp's infirmary, which is needed quite often. There are four floors including a basement and an attic in the Big House. It is home to Mr. D, Chiron and Argus.
Rooms in The Big House
Wounded Greek demigods would usually go here for treatment or healing. Demigods from the Apollo cabin would most likely help out as their father, Apollo, is the god of healing. But Argus also helps out in the Infirmary. In The Lightning Thief movie, there is an infirmary but no mention of the Big House is made. In the film, the infirmary has cots on both sides with little tables next to them and wooden trunks at the foot of the cot, a cart shelves stocked with medical supplies and herbs. In The Lost Hero, Piper McLean woke up in the infirmary after fainting in Hera's cabin.

The attic is the home of many things. It holds many trophies that demigods have taken from monsters and other situations, such as quests that demigods have taken. The attic used to hold the Oracle's body (or what was left of it), which told prophecies for the quests of the campers, but since the Oracle was replaced by Rachel Elizabeth Dare, prophecies are now told in a nearby cave. Or, like in The Lost Hero, if Rachel would suddenly black-out into a prophecy, the campers would place her on a stool.
This is where Chiron and Dionysus play Pinochle most of the time. It is furnished with lawn chairs and tables, like a vacation home. Lawn chairs are occasionally upgraded with pillows and a blanket to help ease a wounded (or recovering) demigod. The deck wraps around the Big House's entire perimeter, giving an excellent view of the Long Island Sound and Camp Half-Blood's immense forest.
Chiron's Office and Apartment
Chiron has his room and does official business from his desk in his office. It has a record-player and a full-screen video (where the orientation film watched by all new campers is located). He also has a computer and a boom-box (with the most horrible music from Italy with a bunch of violins and some guys singing opera in Italian), which was used by Annabeth Chase and Percy Jackson to scare away the Stymphalian Birds. Chiron's apartment is also located here as he lives and also gives training to Percy and other demigods at Camp. The whole room is bronze shielded, due to the fact that "technology and demigods do not mix."
This is the room that Chiron holds all of the head of cabin meetings, as seen in The Titan's Curse and The Lost Hero. It also has a ping-pong table, as that is the "table" that the council meetings are held around.
The only mention of the basement is when Chris Rodriguez was taken care of in The Battle of the Labyrinth by Clarisse La Rue. Chris Rodriguez was driven insane by King Minos in the Labyrinth, and Clarisse was attempting to calm him. The basement is a storage space for stockpiled ambrosia and strawberry preserves.
- The Big House is described sky-blue, but it is brown in The Lightning Thief graphic novel.
- The Big House originally slept all campers but fights broke out and because of rivalries between parents, they built separate cabins.
- The Big House got its name when a camper said "Now that's a big house" and the name stuck.
