Public works projects
Meeting a project's donation goal
are a feature new to Animal Crossing: New Leaf
. Projects allow the player to customize their town by adding new buildings, upgrading existing buildings, and adding various features to areas throughout their town
. These projects are initiated by the player
, who now takes on the role as the mayor. The concept is similar to the ability for the player to use the town fund
in Animal Crossing: City Folk
to install a new bridge, fountain, and a windmill or lighthouse; in New Leaf
, however, the options are more diverse and customizable.
 Initiating a project
Ceremony celebrating a completed project
Only one project can be worked on at a time. Players unlock projects when villagers want to speak to players. Once projects are unlocked, the player may choose a location to start a selected project: Isabelle, the mayor's assistant, will follow the player until he or she chooses a location for the project. Isabelle will either approve the location or state why the location is not adequate (not enough space, too close to a home, etc.).
Once the location is set, the area is fenced , and Lloid appears. Once spoken to, Lloid will state how many bells are required to build the project. Players are mostly responsible for the funding, though villagers may sometimes contribute. Once funding has been completed, the new structure will appear the next day.
Once a project is fully completed, a ceremony will be held in which Isabelle announces the completion of the project to villagers and the player.
