I'm considering a simple home addition and would like to be able to
come up with a simple rough estimate. The house is single storey with
a peaky A-frame attic and is 30 ft wide at the base of the end that I
would be extending. I would like to take that end out another 24 feet.
That means-

80 lineal feet of concrete footing.
80 lineal feet of exterior framing and sheathing.
1350 square feet of rough flooring.
875 square feet of roof and roofing.

If I carry on like this and calculate the materials cost at Home Depot
prices will that result in a somewhat meaningful number?

Thanks!

I think that the $65.00 a foot is a little low. Since the war concrete,
lumber and plywood have jumped 20-40% depending on where you get the stuff.
A friend wanted to pour an simple pad in his back yard. Cheapest concrete he
could find was HD @ $136.00 a yard used to be $85.00

You forgot the stem wall, insulation, windows, wall board, electrical,
plumbing?, paint, exterior siding and the list goes on.
Results will vary depending on where you live
