I agree with Ar that you simply need a join table to hold the relationship from the Company to its Headquarters instead of using an object hierarchy and inheritance. Using Modules to insert and
class Company company_id end class Building building_id end class CompanyHeadquarters company_id building_id end Having the CompanyHeadquarters object may come in handy if you need extra information about the Headquarters building that is different from a normal building.
