Hi, new to the site, but have been reading tips for years. I am looking to add a laundry room to my house. The space where I am looking to add it is currently a "nook" in the back of the house. It is a space that is currently covered by the roof and bordered on three sides by exterior walls. I would like to build a wall to close in the three sides. However, I am in need of advice as to how best to install the footers. Also, to run water/electric to the space, is it advisable to go through the current footers and open the crawl space to that area? Would appreciate any/all advice. Thanks
