The problem with island sanctuary is that you have to be online and in your island for it to even be accessible to anyone else.

I'd rather see instanced houses that are accessible from a directory in the wards, just like apartments. At least that way you can make your house available for the public to visit. They should also be mutually exclusive with ward houses (but not apartments), so that people can choose between having the neighborhood feel or choosing the house size they want and not having to deal with auto demolish.
