About
 is a summer mansion owned by Mr. Burns.

Upgrades
During the event it behaved as an upgradable building with (theoretical) maximum of 10000 upgrade levels. In order to upgrade it, the player had to pay Square Inches depending on the level. Each level had a cost of six times the level wanted, i.e. level 7 required the Mansion to be on level 6 and 42 Square Inches. All levels gave an increase in tap radius. In addition, level 5 unlocked the West Wing façade, and level 15 unlocked the Both Wings façade. Once a façade was unlocked, the player is allowed to switch between all available ones.
