This is really too obvious but don't use a metre high table!
Even for normal racing, that is higher than normal - my experience is that a comfortable height is somewhere between 750 and 900 mm in height.
In this case, I would suggest starting with the lowest level no more than 300-400mm above floor level.
You might consider reducing the total elevation change in the layout, just a little.
Alternatively, start the layout right on the floor and work it up the front face of a table of some sort.
Other thoughts - at 4 metres square, there will likely be room for some access to the track inside the circuit.
