I currently have a 32 inch exterior door to my house and I would like to install a 36 inch. The room in which the door will be installed is currently just studded walls. The problem I notice is there is no bottom plate. Well there is its just in the basement. about a foot below the first floor. Is it viable to frame a larger door or am I SOL? The house was built in 1920.

Has anyone ever done or heard of this being done before? I recently bought a door with 2 sidelights and paid to have it installed. I reviewed with the contractor what I wanted to done. He agreed and then didn't do any of it. So you know the rough opening for the new door was 3/4" bigger then the existing opening, which I showed the contractor. I asked for the following, remove a jack stud on each side and replace with 5/4, he agreed. I asked him to add a header hanger for support, he agreed. I asked him to remove the entire sill, which I told him was partially water damaged, and replace with a single piece of material sufficient to raise the door sill .5"s, he agreed after I showed him the header was already 8" higher then the existing door opening and framed down with 2x to create the nailer for the door. What he did: remove the jack studs and build up to 5/4. No Header Hanger. Replaced part of the sill and did a build up to give me the .5". These is almost no shimming, he said he just used the nailing flange. the only shimming he did was under the sill so about half of it isn't even glued to the sub-floor. So I ask for any thoughts/advice on removing it to correct the structure and prevent the upper corner on the latch side from striking the jamb?
