Three phase or single phase

Hi, I am about to retire, (from farming) and will move to a normal house block. I have all 3 phase equipment (contractors saw, planer, thicknesser, 2 lathes).
Is it worth keeping the older 3 phase gear and upgrade the suburban house to 3 phase, or buy new single phase gear. Some of the equipment is old, but in good working order.
Thanks, Clarky.
