    Additional Notes
    1. This is just a basic estimate on materials made from guesses with my drawing. Without knowing exact dimensions of planned addition, materials chosen, and how you plan to finish the interior of the addition I can’t determine a cost.  (use $70-$100/sq ft for Total Costs)

    2. Home Depot Kingshighway, St Louis MO for Material Costs 
    3. Labor Computation= Materials x 3 – Materials (for rough estimates only)
