The survival hub is where you spawn in at when you join survival, you cannot build in the hub, the hub has a lot of NPCs [Non Playable Characters] with whom you can trade money for items, you can see your money by doing /bal. In this hub you can also sell some items for money, however items are sold for a lot less then they're bought.

While the hub may be fairly small, the surrounding area that is protected is very large, which means you’ll need to walk till you see a large tower in the distance, after you pass this tower you will be able to build and break blocks and claim the land, alternatively you can do /wild to be teleported randomly to a new area, out of the bounds of spawn and most likely not too near to anyone else on the server.
