I generally include the longitude correction in the sundials I design and build. The specific design for the location (latitude, longitude and orientation) is what makes makes the dial special. If you want something ordinary just go to your local garden shop and buy one of the mass produced commercial dials. If you want to create something unique make it specific for the location.
I also like to include other specific design features to reflect the location. For a remote alpine hut in the Rocky Mountains I carved the gnomen in the shape of a mountainer's ice axe. Although the design was unique for this location, it still travelled the world. A couple from St. Moritz in Switzerland used a picture of this dial in their wedding invitation. I would not worry about moving the sundial. Leave it for the new residents I have left half a dozen dials at places where I have lived across Canada. Leaving the sundial is an excellent way of leaving a reminder of my history. Moving to a new home gives me the opportunity to design and build a new dial.
