We're considering altering an existing load bearing wall 10-12ft length ( possibly an existing header already above, and definite header below floor in basement with support columns ) in a 1967 rancher , truss roof system, with basement as stated . We want to turn the end support beams of the existing load bearing wall into support columns. We will obviously get a permit and involve a structural engineer to a degree , but want to know ; if there is already an existing header, can you alter the existing load bearing wall support ends into columns, and can the existing header above just be re-enforced by said beams/columns in the correct load bearing areas without having to add another support header ? Weve looked all over the internet for days for this question and it is not answered anywhere we look .
Update
Again, that's if there is a support header above . We haven't found that out as of yet . We don't want to build another wall : we want to build support columns using the existing load bearing wall guts of that already bares the weight at the ends .
We're looking for cheaper alternatives rather than replacing a 10-12 foot beam and thought support columns at the precise load bearing areas could achieve an open concept load bearing wall image in house
Thanks everyone . And thank you Michael . Theyre plaster walls , truss system roof ; which we've read some truss system roofs built in the late 1960's may not need a middle load bearing walls, that's why we will most definitely need an engineer : but are just wondering if there is an existing header can you support it with columns in the correct load bearing areas if possible, and properly designated by an engineer ?
