In mathematics, a group is an algebraic structure consisting of a set of elements equipped with an operation that combines any two elements to form a third element and that satisfies four conditions called the group axioms, namely closure, associativity, identity and invertibility.
1 A lot depends on how much is included and the quality of the final project. 2  Finishing a basement in a relatively new home can start around $20 -$35 a square foot, or $30,000 -$70,000 for 1,500-2,000 square feet -- but it can cost $100,000 or more to create a fully-finished space.
What's the bottom line? The advantage to finishing the basement in this example is that the price to finish the basement is $35 per square foot, which is quite a bit less than the cost of finished living space in the home at $182 per square foot.he cost of your basement finishing project can vary depending on the finishes that are chosen and the amount of space to be finished. Industry standards state that the average cost to finish a basement is $30 per square foot, but the following project comparison shows how this benchmark may or may not hold true:
