I see that the reconstruction of the Pavilion will have a somewhat different 'end wall' for the roof, where the modification protects the wall from the weather better than the original version. [
thumbs up]
Here is the original structure:

In that photo, note how the roof and the end-wall meet without any overhang.
Compare that to this photo Mike posted above:

In the second photo, you can see that the framing for the vertical end-wall is inset from the edge of the roof. That provides better weather protection for the wall, and the extended roof provides a slightly larger 'rain shadow' for those near the edge of the structure when its raining.
