Electrically operated main water shut-off valve, and water sensors at appropriate points; laundry room, under sinks... Smoke detector network, rather than just individual detectors/alarms. And, I have never understood floorplans that put the bedrooms on one side of the house, and laundry rooms on the other side, or another floor, usually through the kitchen. Laundry room - bedroom proximity would seem logical. New laundry appliances are remarkably quiet, but such a room could still probably use some extra sound/vibration isolation from the bedrooms. A rooftop observatory would be neat - how's the light pollution in your area? If the 1200' is marginal for a runway, how about a firing range? Neighbors still might be a problem.
