Fallout 3 locations project
The Concrete treehouse  is a small makeshift house in the Capital Wasteland. It is an unmarked location southeast of Fort Independence, halfway in between the Fairfax Ruins to the north and Andale to the south.
The Concrete Treehouse is a makeshift hut built into the remains of a destroyed building. Slightly elevated above the ground and only reachable via a small ramp, it contains a bed and is home to a scavenger and his dog. A ceiling-mounted automated turret provides additional protection from a group of raiders that spawn nearby. With a bed to sleep on, it can be used as player housing.
- Tales of a Junktown Jerky Vendor, in a pile of ruined books, next to the mattress.
The concrete treehouse appears only in Fallout 3.
- The Scavenger at this location may spawn as either male or female with little to no difference in their trading skills, price and or variety of items for sale.
- The turret is not allied to the scavenger. The scavenger is not in the turret's line of sight and simply appears allied to him.
