Installing an elevator

First question- why didn't we do that when we built this house eight years ago? It would have been sooooo much easier. However, here we are. Jon really needs a knee replacement, and he is convinced that he'll be a crippled old man- any day now. Where to put the elevator to run from the basement and garage, to the main floor and then up to the top story. Well, it turns out that it will be in my closet with the main floor door opening into the bedroom. Fortunately, the closet is 10.5 feet by 22 feet. And the elevator cab will be on Jon's side taking up 4 by 5 feet. That's really ok, because we can put new rods, shelves or whatever on the walls where the elevator is. That is really the least of the problems though. Number one that is being worked on now is that the upstairs heating and air has to be moved, and the ducts in the basement also must be moved. A large mess and expense. The concrete floor in the basement has to be cut out, and framing is necessary. Electrical work is part of the project along with painting, etc etc. My nerves are ok for now, but I'll let you know more later. I'm really afraid to get on the elevator , but Bella will enjoy it as her arthritis makes going up and down difficult.
