I have been going back and forth for weeks to wheter installing a walkout door or an egress window in my basement. I have a ranch house about 1300 quare feet and need to create more room for kids. I currently have about 3' of the basement exposed outside and have windows in the place where I would be cuttting out the door or egress window. I really want the install the door because now I only have a 30" door to the basement and can not fit larger items through it. If I install the door I will need to dig out the ground outside and form walls, steps and drainage. My yard i level as can be and drainage would have to be tied into my basement floor drain or a sump door at the exterior door landing. I plan to build the wall and steps with Allan Block reataining wall blocks. I then plan to have a patio door installed. I am worried about the size of header needed above the door. The area where I want to install the door is 88" high. Any suggestions on this project would be GREATLY appreciated. Thank you.
