How to Expand Island on FarmVille Tropic Escape

Island Fever! FarmVille Tropic Escape is absolutely addicting. As you purchase more items and land plots, you will find that you need more land space to place your field, Sushi Stand, Mill, Artisan Workshop, and many more. That is, you need to expand your island area.

Areas where you cannot place items will be highlighted in light green boxes as shown.

Unfortunately you need to reach to Level 10 to expand your island. When you do reach Level 10, items will pop up on the screen as shown below.

To find the items required to expand the island, they can be found at the Coral Reef, using your gems (I don't recommend using your gems since the only way to get more slots in your shops is through gems), or through treasures found at Temple Dive.
