With that and the collar ties
that needed to go through the wall itself, Amy and Jeff stopped using the forms and hand-built the wall around the collar ties

, the structural members that support the rafters.
To reinforce the remaining structure, heavier floor joists replaced ceiling joists, rafters were doubled up, and collar ties
were added near the roof peak.
The examples on these pages show a variety of solutions: removing some joists and doubling up others, tying the roof rafters together with collar ties
(cross-pieces that parallel the old ceiling level but connect at points higher up the rafters), or taking some of the roof load off the walls and carrying it with beams added at the ridge or at points along the rafters.
