In terms of driveway material costs, concrete averages around $3,540. The cost of concrete driveway pavers will increase for a driveway that is stamped and colored, assuming you want to customize the looks more.
Buying a pole barn from a manufacturer and having it installed costs roughly: $6,000 to $10,000 for a 16 x 24 economy unit. $8,000 to $12,000 for a 24 x 24 garage-style barn. $15,000 to $25,000 for a 40 x 60 storage facility. $25,000 to $30,000 for a 36 x 48 barn.
Re: pole barn concrete slab. Instead of continuing to hijack another thread, I'll start my own. I'm getting prices for a 30x48' pour in my pole barn. Got 2 prices, getting a 3rd. One guy said to box around the poles about 18 away, to not pour the concrete against the poles, and then fill this later with grout. This is to keep movement of the poles away from the slab to prevent cracks.
