The Modern Mansion is one of the houses in Adopt Me! that can be bought using Robux. A player can buy a Modern Mansion for 350.
The interior of the house is nearly identical to the Gingerbread House. It has two floors, with the doorway being on the side of the house, unlike the majority of the other houses in Adopt Me!. There is also an indoor pool room located right in front of the main doorway.
In total, the Modern Mansion has 7 rooms including bathrooms. The first two rooms come with a bathroom pre-attached to them. The third and the fourth rooms are attached to each other, which means that a player would have to go through the third room to reach the fourth one. There is a bathroom attached to the fourth room. Unlike all other rooms, the third room does not directly have a bathroom attached to it. It also comes with 4 trees outside the mailbox, and three planters with trees on top of the roof.
