Only to confirm that anything between 18 and 24 months for building a house is plausible, anything less is usually "wishful thinking", there may be some particular exceptions, of course, but my (close to 40 years) experience in the field tells me that whenever someone tells you 12 months or so they are forgetting half of the things needed or they are overly optimistic. And, to respect an 18 months timeline, you need a supervisor and accurate site and construction planning and a bit of luck, if any of these lack, it is going to take 24 months +.
