I have a preliminary house plan that I paid an architect to hand draw to scale (1/4" to 1 foot). There are no construction details yet. I have drawn in changes myself and haven't had any trouble getting bids for materials, drilled well, cabinets, trusses, etc. I might even tackle the basement myself since I have a crawler/loader for farm work. I hate to pay an additional $1500 for a detailed completed house plan. Wonder if I can build from the preliminary plan. I also hate to have copies of my house plan shown to other builders as samples of the architect's work. I hope to frame up, do the wiring, plumbing, duct work, etc. myself after retirement soon. Building codes are non-existent in the county I will be building in. The architect was saying he might want to get an engineer to figure some details. This would bring the cost up another $400 or more. Maybe I could find a computer assisted designer with a more reasonable rate that would show construction details.
