single responsibility principle

The Builder Pattern helps separating the construction of complex objects from the context where they are needed. Additionally, the pattern also contains different variations of objects which have a common construction procedure.

This makes the builder pattern convenient to use when complex objects needs to be created and well aligned with the Single Responsibility Principle. (SRP)

Given that the builder pattern sets up a method for constructing new objects, it is understandably categorized as a creational design pattern.
