That led me down a long old rabbit trail of looking through old photographs, and I came across this one from a year or so back:
I started to have a go at re-working the image in a different way, starting with re-cropping it to focus tighter on the door. The door was always the centre-piece of this image, and the thing that does it for me is that the door is slightly ajar. I kept the Monochrome adjustment on the image, but then also added Aperture's Color Monochrome adjustment. By default, this adjustment has a strong sepia tone to it. I dialed back the intensity of the color monochrome from 1.0 to 0.4, which was about the lowest level that left the effect perceptible. I also removed some of the rubbish on the ground with Spot and Patch.
I"m really happy with the result:
