"Office Outpost" is a side quest available in Dying Light. This quest is offered by Savvy at the Embers' Tower. Kyle Crane has to enter the office outpost through the roof and an elevator which is guarded by a number of Rais's Men who wield rifles, kill all of Rais's Men who also wield rifles inside, and leave through an elevator leading down to the ground floor. Upon completion of this quest, the rooftop office where Kyle entered initially will be unlocked as a safehouse for Kyle, the ground floor will no longer have an electrified fence and a trader will also occupy the safehouse for the rest of the game.
Savvy told me about the office building turned by Rais's thugs into their outpost. I'm tempted to make an "inspection" there.
