It's all downhill from here

[Bill Dufour]

Pour a flat slab outside of the entrance doors that extends well past then house. Install a wide cast concrete staircase up to the driveway with a landing on top. Pour a concrete rail on each side that is a few inches taller then the steps. Make a cart, with flanged wheels, to ride on these rails and use a rope to hoist it up and down.
Actually all you need now is the sat sides of the steps. the steps could be added latter. The handrail will have to be well outside the rails but it can lean inward.

sorry for the poor photograph but you get the idea. I believe the handrail was added latter. nothing wrong with 1939 technology.
