Addition built on Piers vs. foundation
I am considering adding a bump out to the first floor of my house. It would be approx. 8'X14'. It would house a small powder room and breakfast nook. One contractor has reccomended building it on piers to keep costs down. He tells me insulation like Icynene would keep the room well insulated (we live in New jersey). Please give me any opinions/experience with this type of construction. Pro & Cons etc.
