The panel will go where the box is. It will be a MB nippled into a new meter can. There is 42" from grade to the bottom of the window sill. I have put in my bid that the gas pipe must be shortened just because I don't want to deal with it.
That is the back porch of a 1900s Victorian. At some point someone closed it in for a laundry room and stuccoed it. The rest of the house is original red brick and looks great, just seeing the back porch does not do justice to the rest of the home. I wish they would tear it off and rebuild it to what it was originally.
