Couple of renderings from Revit. Neighbours house on the southwest side is included. This first one is the rear, and the second one is the front again - South side.

Sun is modelled as at noon on the winter solstice, but it's probably off by about 15deg since I haven't adjusted the house orientation. The aerial view in the previous blog is aligned to true north, so you can see the streets are tilted pretty close to 15deg to the west.
