adding an attic bedroom
I have recentaly added on to the back of my house. I added 18x54 2-bedrooms and a bath and large living room. the old section of the house was 30x54 and the roofing section is a truss style. when i added on to the back I extended the gable of the old roof ( 9'9") and framed up regular rafters for the new roof.The back of the old roof is now in the attic of the new. I now whant to add a bedroom in the attic space. But this means to get enough space i need to cut out some of the trusses to have living space.What i want to do is run 2x8's along the cieling joists of the trusses they are 2x4's now.and nail them to each other for support. then brace the area that i will cut with a strong back and some 2x6's. Then just frame up with standerd 2x4 framing for the bedroom. can this be done safely?
