This is my best guess for a forum to post this on. I have a fairly large area ( 14' x 24' ) in the basement of a new home and will be starting new layout from scratch. Have some rolling stock. Disadvantage is that I cannot get a 4 x 8 sheet around the corner to the stairwell. A sheet ripped in half either way will work. Question: Has anyone used or considered using the IKEA Ivar or Grom product as the base benchwork. My preference would be Ivar. The 124 cm height is approx 48" to which an L girder layout can be added giving stability to the top. Leveling screws would probably be needed. An advantage is that shelving, etc. is available. Your comments are appreciated.
