View from above of the different floors next to the blueprints of the house used in the show.
For the basement I haven't found the original blueprint, but the images from the show were enough to estimate its size and proportions, even if it was slightly modified during the course of the show.
My version here comprises the original basement and an expanded area that sits under the rest of the house. I added numbers to my floor plan to describe every area visible.
This is the main basement area with the staircase and an additional laundry area.
Archway area next to the staircase where Prue used to have her darkroom for photographs development.
Small connecting area to the expanded basement
Main hall of the expanded basement that opens to four different rooms:
The numbering on my floor plan explains where everything is located:
Living room with bathroom under the staircase
Kitchen bathroom (I added it here because in the original floor plan there's a quite large unused area behind the dining room fireplace)
Staircase access to the basement
Unfortunately the makers of the show didn't care at all to build the house in a way that every floor matched with the one below or above, probably for filming reasons. Hence I had to make a few modifications in order to fit everything together and avoid the house to look disproportionate from the outside.
I placed some numbers on the show floor plan, so you can understand the modifications and where they occurred.
The bay window has been slightly resized, because the game doesn't provide half walls lengthwise, hence having two wall-lengths for the oblique sides of the bay window would have been too much and not proportionate enough.
The closet has been removed from its original location because it would otherwise be floating midair. In its place there's a window now. It has been moved next to the fireplace at No.3 where there was a door already that supposedly lead to an en-suite bathroom that has never been shown in the series.
Here is located the new closet where I placed a window that's similar to the one used for the bathroom.
The door of the closet has been moved to this wall so to maintain a door in that area, but this time it opens to the en-suite bathroom.
Prue's en-suite bathroom:
The area marked by No. 4 and No. 5, which on the plan reads "to Piper's room" has become the en-suite bathroom to the master bedroom, because that area (considering the positioning and size of the walls of the first floor underneath) would have created an area too small to be a bedroom.
In Season 2, Ep. 10 we have the only scene where Piper's bedroom is "actually" shown without using Phoebe's room, which is located at the end of the corridor and right above the front parlor (that room has doubled as Piper's, Phoebe's and Paige's room throughout the 8 seasons of the show).
After the intro credits, Phoebe is seen exiting the bathroom and going through the small vestibule outside the master bedroom (prue's bedroom) and opening the other door located in that area, which leads into Piper's bedroom.
As I said, this is the only time this location is used to portray Piper's room and this confirms also the information present on the second floor plans posted here, plans used in the show.
On the show's floor plan, at No. 6, there is a door that has never been open in the show, so we don't really know where it leads.
When I built the house, that area is right above the kitchen, which makes the perfect spot to create a room of decent size. This is the reason why I thought it was the best location where to place Piper's bedroom. This also helps to maintain her room in that area of the house.
This room has been modified in two places:
At No. 7 I replaced the door with a window because that wall is an exterior wall, thus preventing me from having a door and a corridor (that theoretically linked the master suite with the bathroom). Also the game limitations (aka half walls, etc.) would have made everything too much disproportionate.
The window between the shower and the tub has been removed because it would have opened into the room located at No.8.
Located at No. 8, this space was big enough to place a relatively small bedroom or, as mentioned in the series, Grams' sewing room, if one's inclined to change it into that.
Located at No. 9, there's a fairly large area that corresponds to the front of the house and is located exactly above the entrance hall. On the outside there's a single window, which enabled me to create another large bedroom, which can be accessed by a door placed at the end of the staircase.
The numbering on my floor plan explains where everything is located:
This area of the house has been substantially modified in order to make it fit logically within the frame of the house.
The alterations affected the length of the attic and its shape. In the original pans, the upper area of the attic (where the 2 chimney boxes are located) would have protruded well off the wall of the building, so I had to shorten that area quite a bit and make some changes to its proportions because of the game limitations and the actual shape of the house. Despite all of that I tried to line up the bay window you can see on the right of the plan, to the bay window of Prue's room, in order to create a turret, which is one of the many feature a Victorian house has, and I think it adds to the charm and magic of the house itself.
