All buildings and decorations not displayed at the location are stored in the Storage.

The warehouse is located in a separate tab in the Building Gallery. To open the Gallery, click on the crossed tools icon in the lower-left corner of the screen in the City. In the window that opens, select the Storage tab.

For each item, the card shows its quantity (for example, 2 bushes). The number of places in the Storage is unlimited.

When you click on the item card, the Storage will close and a control menu will open in the City, where you can place the item at the location. For more information, check this article.
