Does anyone have any experience with removing a second floor bedroom to create a first floor vaulted ceiling? The home is a cape cod style where the rafters land on the first floor walls and the 2nd floor bedroom that we are removing has the knee walls on each side. The rafters are currently 2x6 at 16"oc. with a 2x8 ridge beam. The 2x6 rafters are long. I'm guessing approx. 20 feet in length and I'm thinking that the kneewalls are really helping to keep the 2x6's from bowing. Also I'm thinking that the floor system for this 2nd floor bedroom is keeping the walls from bowing outward from the pressure from the rafters. Has anyone out there done this? I'm sure it can be done, but would love some input from an experienced remodeler. My thinking is to almost create a different interior ceiling pitch so I can get more insulation up there, as well as using 2x10's etc. May be I need to add a new ridge beam under the current one as well? Just thought I would throw it out there to see if anyone has any input. Thanks for anything you have!!
