I am building a 24x 26 foot addition. The first floor is completely open. It is a cape style house with 4 foot kneewalls on the 2nd floor. Their will be two bedrooms upstairs. I have thought about two or three 18 inch by 26 foot LVL's glued and possibly through bolted. Will this be enough to support the 2nd floor without a post?
Any help would be greatly appreciated. Silas
