In Boom Beach the Headquarters is the hub of your base. Its level determines which buildings you can build and which troops you have unlocked.
Your entire base set up should be geared around protecting your Headquarters, as losing it in an attack results in a loss, costing you resources. You should therefore set up most of your defenses within range of your Headquarters.
Destroying any other building in your base also damages your headquarters (10% damage of the building that was destroyed). You should keep this in mind when planning your base, as putting a lot of buildings unprotected will allow an enemy to make a significant dent in your HQ’s hit points.
There is no penalty in upgrading your HQ i.e. it does not open you up to attack from higher players, or result in reduced rewards from lower level players you attack. It is therefore best to upgrade as soon as possible each level.
The first table below breaks down the build cost for each level and the time taken. The second table details the buildings unlocked for each level.
