The floor plan on the third floor changed considerably because of a concentration of closed walls that were used to support the east/west roof ridge. Pre-Existing Floorplan below.

Those walls were replaced with one long engineered ridge beam that rests on the east/west masonry. This allowed a very congested floorplan to be completely opened up. There was also an additional cross beam put over the north/south collar ties that tied into the main beam to stabilize the roof in both directions.
The R45 insulation requirement was similar to the vaulted ceiling room with tall sistered rafters. These however were only spray foamed to maximize headroom.
The biggest challenge was to retain both bedrooms and put in a full bath that had a shower height that met code. Unfortunately the roof line wouldn’t permit it. Plan B became a suite with a flex area with a ¾ bath with storage and a single bedroom. All the cabinetry was built on site and the vanity also used floorboards pulled from the 2nd floor landing.
Because of the amount of closed walls with doors, we ended up with a lot of extra five panel doors. Three of those shorter doors ended up being cut down as utility doors on the attic crawl spaces. Two of those doors provide access to AC handlers. One being a traditional HVAC the other a set of mini-split handlers.
