Who has built with an architect? Experiences??

then just name the price per m³ or what was agreed upon ^^

There was not a 4 at the front and all costs were included - although the garden only had the essentials

okay and then plus incidental construction costs or architect's fee?

No, I said "everything" after all

aha, well, with you in the Münsterland that might still be possible

Everything? So with the property? The term "everything" or "everything included" is rather undefined. Calling an uninitialized variable, error & program crashed.
