That sounds like the right decision, Jim. You will be able to enjoy it without all the effort to get to it. What you'll do will give you a lot of pleasure! My sister had a large sunroom at her last place, and she had it full of wonderful plants, and even grew some food crops.
My greenhouse is up the hill from our house, and it has gotten hard for me to get to it as much as I'd like. I would have loved having it right by the house, or attached to the house but our house pad is too small and we couldn't afford to have it enlarged. Even our well house and garage/workshop had to be down the hill. My back problems have me using a cane now, and it sure makes me wish it wasn't so far away. I've been thinking I might need an ATV to ride around the property.
