island far away

Next to the home island we have the island Far away I believe its called. I have defeated all of the enemy's in the first sector and have an island store house on the land already, I also built another but that didn't work. I have sent an explorer out to look at it but I still cant build on it. only the 4 plots to build on are still available.

Any help is much appreciated

you need to buy a sector deed from the merchant for beanstalks, and place it on the empty sector, then you can build a storehouse and then other buildings

Thank you very much Kit_ I will Get the Beanstalks and buy the sector deeds.
