Yes - planning on building a workbench, thought rather than re-invent the wheel I would look for some dimensions and ideas from others.
While we are waiting to see if @Baggs can answer your question I thought I would mention there is a similar workbench with instructions on our website. There is a D.I.Y. portable workbench which could have the back section attached like Baggs version and there is no need to add the wheels.

iv just done a rough drawing of what i remember.
