Buildings are items that gradually gain you more resources for buying more buildings/upgrades. Each building has an individual resource per second production and increase in price each time you buy one. Wall Destroyer currently contains 14 buildings, 6 of them being unlockable by purchasing specific upgrades. Each buildings damages the wall by giving cash/wall damage, except for the Brick Factory which only produces bricks. Reality Compromisers produces fourth wall bricks (base 0.1 fourth wall bricks a second) as well as attacking the wall. Buildings usually cost cash, but some of them require other resources.

Each building's price is calculated with the following formula, rounded to the nearest integer:

where M = number of that type of building currently owned.

Or, equivalently:

Therefore, the cumulative price for N buildings is calculated as a finite geometric series:
