I do not think that you should go for ready-made plans. Every person has his own requirements. In fact, all the family members usually have different habits and hobbies. For their convenience, comforts you should hire an architect. Also, collect thoughts from all the members regarding the problems in current home and expectation from new home. It is very important part, which you should execute first before hiring. All the requirements and thoughts should be conveyed to architect.
