What is the difference in price between a closed staircase and an open staircase given that they shared similar finishes?
Depending on the style of staircase chosen, an open staircase (having similar finishes) will approximately cost $1400 more than a closed staircase due to the construction methods used for supporting the treads as well as the type of materials used to finish off the staircase is usually of a higher quality.
