Great idea for a thread.
I just picked up a 1941 cape cod in Northern VA.
Great house. On my list, I have run new electric through out the house. Trust me, your job is half done, I already ran a new circuit to the finished attic, and 3 new circuits to the kitchen! You'd be a gem if there was one for each room.
New recessed lighting in the living room and hall way would be ****en! There's already an available abandoned switch by the entrance just ready for the purpose!
And when that's done, I'd love a new bathroom in the basement, along with a larger window and window well for an emergency exit down there.
