The "Flynn-Fletcher house" is the house of the 2nd Dimension Flynn-Fletcher family, akin to the Flynn-Fletcher house from the 1st Dimension. It was first seen in "Phineas and Ferb The Movie: Across the 2nd Dimension".
In terms of structure, the house is identical to It's 1st Dimension counterpart. However, since Doofenshmirtz's reign emphasized the lavender, green and purple color scheme on all of Danville, the house's color had to be updated with the aforementioned color scheme.
Later, after Doofenshmirtz's arrest, the house looks more or less the same as It's 1st Dimension counterpart. The house is divided in two stories:
- Entrance: The same as the 1st Dimension house, but with the color scheme.
- Living Room: Phineas-2 and Ferb-2 are fist seen here, playing a game of Doofopoly.
- Candace-2's Room: The only room seen in the 2nd story so far, first appearing in "Tales from the Resistance: Back to the 2nd Dimension". Unlike the room from the 1st Dimension, Candace-2 uses this room sometimes to train herself in case a threat to the 2nd Dimension arrives.
- Panic Room: Not actually seen, but Linda-2 frequently goes there for unknown reasons, probably due to fear of Doofenshmirtz's rule. After his arrest, It's possible that the panic room is used less frequently.
