"what is the most time consuming remodel you have done and are still married?"
That's a good question. Makes me laugh.
In the 90's I was doing work on "our" home. After doing about $90,000 worth of improvements to the home, I was told that from now on I wouldn't get a say on what projects I would be working on and paying for. It was too stressful for her to discuss what I was going to do for her. I decided the "job" was no longer worth the reward.
More than ten years later, I now find myself doing home improvements for my GF, and she thinks I'm wonderful. The biggest problem, is that I now have two homes to improve. Hers and mine.
But I'm having fun doing it.
