Okay, this is pieced together from episodes, screen caps, descriptions, and blue prints others have done. Some of which made no sense when pitted together. So I kind of cobbled it together as best I could. Now the only differences between the cannon and fannon house plans are the following:
Wyatt took Piper's old room
Chris has Phoebe's old room
Lucas has Prue's/Paige's old room
Spouses/Boyfriends live with their respective partner while at the manor.
The unknown room on the second floor is now a guest bedroom as is Grams' old room, until such time as they get live in houseguests or children.
Now there is also an addition that I'm going to spoil for the lot of you who are reading my Charmed Squared Series over on Y.
So if you don't want to know, don't read this next bit.
The Grand Grimoire, or as the series calls it just The Grimoire, resides side by side with the book of shadows in the attic, and later on the Phoenix Grimoire will also sit there with them. As well as several books form magic school, and copies of Piper, Phoebe, and Paige's personal grimoire that contains the spells they themselves specifically wrote. The charmed boys keep their personal spell books up here as well, except when their working spells on their own, then their personal grimoire is with them. They've added to the protective spells on the attic so they can keep more magical tombs there.
Now you're probably asking yourself how in the hell could a book so evil the pages themselves turned black from its corruption and a book full of morally ambiguous magics sit in the same room as the Halliwell book of shadows? Simply, a power of four spell to bind the book or books to the manor and to the Halliwell line. And over time the power of the Book of Shadows "corrupts" the darkness of the other two and turns them all three into more powerful good magic. Image the book that binds all the underworld's darkest magics together turned to purest good by the Halliwell Book of Shadows? -grins- Yeah I'm also going to throw in some curve balls to the series over time.. Since on the ride to my aunts house I kind of made a full episode guide -smiles-
