Literally Can't build anymore Say WHAT!?

I just stored my Symbol of Hope design I made And it added up to 210 or so items. That is a LOT just for a design that I don't exactly need. So I decided to store the items I used for the design. So that gave me some room to work with. The thing is I got a ton of land but I am afraid to place anything. Guess I'll have to stop designing from here on out. Unless they raise the item cap again....And thanks again for explaining the Bridges...I do got one I guess I can get rid of. I think there is a few others I can get rid of as well. I forgot I also got stuff in the ocean. Like the Water World items. I can get rid of those. In fact everything in the ocean I plan on getting rid of. I don't see the point in the ocean area anymore.

I would think boardwalk pieces would also take up item cap space right? Because they have a item count when you store them. Same with Heights boardwalk pieces.
