Production rooms – Necessary resources for the vault’s survival.

Storage room – Just increases your inventory.

Living room – The amount of living room space you have determines your maximum dweller capacity, even though dwellers will rarely spend time here.

Overseer’s office – An unoccupied room which serves as your mission control room for quests.

You will want two elevator shafts eventually as your vault builds up, to provide maximum mobility.

Elevator – Chained together to make elevator shafts.

Staff your two most butch fighters with their best weapons here to guard against invading raiders.

Vault door – You get exactly one, always on the top floor at ground level.

Utility rooms – Required for vault function.

Rooms can be categorized by function, thusly: Most rooms can be expanded to 3 sections wide and later upgraded. Be careful not to overbuild, because rooms left empty tend to attract disasters.

Over time you will need a good balance of rooms to provide stable function levels. The rooms are what your vault is made of, so plan them carefully.
