Bad experiences with wells in my youth (pollution from phosphate detergents hit 300 feet down!) makes me very hesitant about well water in today's environment. What tests OK today may be very bad tomorrow. So I prefer municipal water supply.

Also, a co-worker and her husband moved into their brand new home last year. It had well water. The well went dry 5 months later. They were not happy to say the least, and major problems between them and the builder ensued. Not what you want.

This year we put in an automatic stand-by natural gas powered generator, which has already been in operation 3 times. In any future home, it is something I would want to have the option to retrofit. They can also run off tanked propane.

Otherwise, it sounds like you pretty much have your dream house already designed...

Good luck!
