The downside of this building is that all monsters inside it will vanish when the building is destroyed. Therefore, you'll have to repair and resupply the housing if the enemy have destroyed your Housing. This building is one of the two biggest buildings in Backyard Monsters, the other being the Champion Cage. To remove monsters in the Housing you either use them in battle, put them in a bunker or juice them using the Monster Juicer. The maximum housing space without the use of Shiny or Outposts is 2,160 (4 level 6 Housings).
