One Man Crew
One Man Crew increases how many walls can be built at once, with ranks listing three, five, and the maximum amount in a line.
How it works
The Building perk list says the first rank can build 3 walls at once, the second can build 5, and the third can build the maximum amount of walls in a line. Building perks are described as relating to placing new walls within a house. The source does not state the maximum, unlock requirements, or costs.
