The barn we will be using as a house addition appears to have been widened many years ago.
The rafters all have about a 4 ft extension on the tops. These extensions look to be different material and different hewing then the other 20 foot section of all the rafters. The short rafter extensions do look similar to the queen posts and cross ties.
All the roof sheathing runs from ridge to eave. Most are one piece from the top purlin to the eave. With short 4 ft sections going from the top purlin to the ridge.
The cross ties are in three pieces - one for each isle. All of the isles are about 12 feet wide...but if the top was widened then the center isle would have been about 6 ft wide. The sheathing on the back gable is also has a vertical section of six foot long boards running up the middle. They are not all the same width as the sheathing on the sides of the gable end.
I know almost anything is possible, but would someone widen the middle of a barn? It looks like it would have happened early in the barns life.
We are planning on pulling the width back by removing the rafter extensions for our addition.
