We had miscalculated a header over a large window on the east wall. In order to maintain our eight foot datum line, we raised the roof about a foot. I love what it does to the interior space. It also leaves us some extra room above the bookshelf for lighting and electric. It is also possible now to add a lofted bed and some closet space in the sleeping space. All good things.
The wall shown above was the first wall we put up and needed to be modified. We added cripples and metal straps to get the wall where it needed to be.
