UPDATED 3Jan2020: A while back we built a set of compact stairs for a small space here at our place on Bailey Line Road, making videos during the process. Click above to watch the main steel body of this stair project coming together with welded treads. As you’ll see, each step has an offset tread shape which reduces the horizontal space required for the staircase by about 50%. It’s a design approach that can work in a lot of small homes places. Welding sand blasted steel, careful measurements and a MIG welder in action are all part of this video.
