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 in 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 their dog. A ceiling-mounted automated turret provides additional protection from a group of raiders that spawn nearby. With a bed to sleep in, it can be used as player housing.

- The scavenger at this location may spawn as either male or female with little to no difference in their trading skills, price, and variety of items for sale.
- The turret is not allied to the scavenger, but the scavenger does not appear to enter the turret's line of sight.
The concrete treehouse appears only in Fallout 3.
