Hmmm, really, you can base residential take offs on square foot costs of similar construction, like $100-$300/ sq. ft. Depending on where you are and the quality of materials and construction. If you need to do a sticks and bricks take off, and incorporate permit fees, design fees, overhead, etc. then you need to account for your costs. If you have never done a take off before I hope you are a carpenter or builder, because you won't know the half of the costs to build. Residential take offs are a pain for a single residence because it is a lot of work for small fee. Do I sound like an "Ex-estimator" ?
I recommend getting estimates from other local builders and compare their prices. Get more than 3 and determine how long they have been in business. This will tell you whether their numbers are good or not. If you are still determined after this to come up with your own version of the costs to build, send me an email and I will quote you a cost for an excel spreadsheet to help with estimating costs. It is not a small undertaking though.
