More often than not it's the back of a house that faces onto the railway in many urban and suburban areas. This is the back of a 1930's house. Originally it wouldn't have had the single storey extension but by the 1970's a lot of houses had acquired something due to the small size of the original kitchens. By now many have two storey extensions or loft conversions.
The drawings show the house with the extension but you could leave it off and replace it with a door and adjacent window to get the feel of the earlier period.
The prototype (which is in Minehead) is on the end of a terrace of similar houses (four in the row). There is an alleyway or path to the side which is why there are no windows on that side.

Nice bit of CAD work there. Did you do it in 2D or 3D and flat shot it?

Thanks. I drew it in 2D. The photo, albeit a poor one, is the real thing.
