It is best to get a lot of people from within the congregation involved in the planning and building process in order to help build consensus and unity. People who are not involved in the process are much more likely to be unduly critical than those who had a part in the process. Said another way, people tend to throw water on other people’s ideas, but not their own. People in the church need to have ownership of the solution, and the best way to make this happen is to make them part of the process.
