Depends on who you get them from.....most architects that I know of charge a percentage of the project.....anywhere from 6% - 15% of the price of the project..... Not having any prior knowledge of how a timber frame home gets built doesn't seem to dissuade them for charging for their services either.... Not to mention the fact that their drawings may not be "stamped" engineered drawings which most metro or cities would require.... nor will their drawings provide the information that the SIPS guys are going to want....I wish I could get paid that much to not know what I am doing....LOL

We usually charge by the square foot and degree of difficulty....And we have actually built a house or two or three
