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.
In addition, a small basement of 700 sq. ft. or less, will cost more per square foot to finish. The bathroom is the most expensive room to finish per square foot, and that cost must be spread over the entire square footage cost â so the smaller the basement, the higher the per square foot cost.The reverse is also true for larger spaces, such as over 1,500 sq. ft.ou can expect, however, that the more features you are requesting, the more expensive it will be. Solid surface counter tops, wet bars, fireplaces, home theaters, architectural features, steam showers, etc., will raise the per square foot cost. The more basic the basement finish, the less the cost.
