I own a live/work loft with 25 foot ceilings in Oakland, CA. I would like to add storage space by building a 300-400 foot catwalk. Any idea what this would cost?

Please provide more details as you have many options that will reflect cost! Floor type, paint finish, existing structure modifications, etc.
