To hold a barn raising, click on one of your barns or sheds and select 'Expand Storage' in the pop up window. That will open another window where all of your storage buildings will be listed. Click the blue 'Expand' button under one of the barns, and you'll be asked to share a message on your Facebook page, asking friends to 'help' you with your barn raising. If you have 10 friends help in three days, your storage will be automatically expanded. Friend who help will earn 100 coins for their efforts.
Once at least 10 friends help raise your barn, you be able to store more items automatically. There are three levels of expansions per building, and each level will allow you to store more items. Below, see exactly how much more space you'll gain per building, per level of expansion, courtesy of Facebook Insider.
Level 1 (Red Barn) – increases storage from 0 spots to 6 spots (your initial purchase)
Level 2 (Big Barn) – increases storage from 6 spots to 11 spots
Level 3 (Huge Barn) – increases storage from 11 spots to 18 spots
Level 1 (Tool Shed) – increases storage from 0 spots to 2 spots (your initial purchase)
Level 2 (Big Shed) – increases storage from 2 spots to 7 spots
Level 3 (Huge Shed) – increases storage from 7 spots to 14 spots
We still wonder -- is this the storage solution virtual farmers have been waiting for? We're still on the fence.
