This is a project I completed last summer. I made some revisions to the original plan. First off, I wanted a corner sofa, so I had to figure out how the corner would work. This was my first ever wood working project and I'm not an architect or engineer, so it was quite challenging. I made a mini model out of foam core to give me a visual of how it would all work together. That was a tremendous help and I recommend doing this to anyone just starting out.
I did not use the part of the plan that included the foot pedestal. Instead, I built the sofa flat on the ground and in the end added store bought feet mainly because I liked the looks of them.
The sofa was built exclusively with the Kreg Jig, except for attaching the horizontal back pieces. I could have use the jig for that part as well, but liked the rustic look that screwing them in to the back braces provided.
I didn't want a padded back because the sofa sits outside on a covered, screened in patio year round. I wanted the ability to take off and wash all the cushions, or to use the bench without the back cushions sometimes.
The 2 sections of the couch were built as independent units and are movable, so one can sit across from each other. Both sections have ample storage.
