New workbench for small workshop

I interested in creating a new workbench for my small workshop (from timber and plywood) to incorporate a small tablesaw, and have space under for some other machines, perhaps with flip-tops so the machines can be a fixed below and raised up to bench level by ‘flipping’ the sections of the bench-top over. I would want to put the bench on lockable castors for ease of movement and to be able to create sufficient space when working on other things off the bench…

If anyone has any photos, drawings, plans or ideas, I would welcome your input, and thank your feedback… ?
