I would just order a laminated kitchen counter to fit the space and then get some of those fence posts and you can drill them in to the top with screws and then you can cut out a hole big enough to put in your machines at counter height with either a air lift or just get a small little table the right height something like a TV tray that is large enough to hold your machine. you and hubby could do this project together. it would be fun.
I am currently sewing on a TV tray in my small meager corner of the living room. will add pic in a few min.
my sad sad corner that expands when kids are sleeping
