Pokémon Mansion is a relatively large building which is most notable for having rare Pokémon in the backyard. You'll find this building in the Nintendo DS video game Pokémon Diamond and Pearl, where it can be found on Route 212. While before you beat the Elite Four there may not be so many rare Pokémon, after you find the National Dex you'll be able to find many exclusive Pokémon including fan favorite Eevee. It should also be noted that (even before you beat the Elite Four) you can catch both Pichu and Pikachu.
Inside of the mansion you'll find many items such as a Great Ball, a Soothe Bell, and a TM87. The mansion is owned by Mr. Backlot.
In all there are four different bedrooms, not including the main living room that you enter right when you arrive.
Differences between Diamond/Pearl and Platinum
There are not aesthetics changes between the two versions, though in Pokémon Platinum all of the maids will battle with the player, while in the original none of them did.
