I am building a large home in NJ with (icf's) insulating concrete forms. The plans have 4 window wells specified ranging from 12 feet long to 20 feet long, to provide egress basement windows. I am trying to decide what is the best way to construct these wells? The main objective is to have something that is presentable and will not make the house look ugly, and preferably enhance the appearance and yet do it at a reasonable cost. The architect specified CMU but it has footings at the same level as the basement footings, which are pretty deep as basement finished hight is 10 feet. Would it be better to use retaining block? Subs have mentioned prices like $30-$45 a square foot to install the retaing block. That seems very high to me. Is it less to install the CMU and footings? Any help or ideas are greatly appreciated. I have calculated a total of 550 square feet of block will be needed, if we don't start at the footings. If we have to go down to the footings I think we are looking at about another 300 feet.
