The Garfield house was only the second house that I ever did. Before you get disillusioned with the time, let me explain that I worked an average of 3 hours a day on the house, during its construction.
Instructions are very concise.
Parts were easily identified and reasonably easy to press out. I did not have to re-order any botched pieces for the Garfield and for that matter any other of the fine line of Greenleaf houses. I have built everything in their line and cannot remember ever finding a damaged or missing piece. The only time I ever attempted to contact Customer Service was to try and find out how to become a dealer. These will last through many, many homes.
