The Microsoft NET Framework base class library BCL already makes extensive use of patterns. Factory Design Pattern in C helps to mitigate this issue by creating wholesale objects using separate methods or polymorphic classes. This doesnt specifically apply to the builder pattern but to design patterns in general.
The Process of constructing a complex object should be generic so that the same construction process can be used to create different representations of the same complex object. For example I might have a Car that uses the Builder design pattern that I instantiate like this. See example code for your builder below.
