Is an elevator the only way to go?
Wouldn’t some sort of ramp be cheaper?
Ramp won’t work due to slope of the yard and other factors. When we built the house 12 years ago we designed the first floor for handicapped access and use ... but didn’t think far enough ahead to put the elevator in then. But we also delayed the cost til now.
