I'd like to install a new window to increase ventilation & install a new window a/c in this room as the long window in the picture doesnt open. The only way I'd get an ideal window placement is if I cut through the shed style roof. I have 2 options for locations but both require cutting either end of the shed roof. The 1st pic would allow me to install a window of about 34"w. The 2nd allows for a bigger window but am concerned removing the roof support.
How feasible is this project? Has this been done before? What do I need to be mindful of? What tools are best to use?
