I also think that architects definitely have their justification. They do not study for a long time for nothing, so that they can be knowledgeable and apply their knowledge.
I thought until recently that an architect is simply expensive but unnecessary. -Until a friend of mine built her house without one. So much went wrong with it!
The costs will probably no longer be roughly estimated by an architect. And before I stand out in the rain without one, perhaps even in the truest sense of the word, I would rather accept these additional expenses.
