Our house (the brown one)
is about 18" from our neighbor to the north (left). (In the photo it looks like we're right next to the neighbor to the south, too, but there's 3-5 feet of clearance there. We're going to repaint this summer, and ideally we'd like to repaint that north wall as well (not only will poop-colored paint look silly with the rest of the house a different color, we're hoping that by going lighter we'll get a wee bit more reflected light in the windows on that side of the building).
What's the best way to get up and down that narrow space?
