You can see the front (east facing) side of the building in Google Maps (sorry, I've yet to fathom how to post a link to a specific point in Google maps - any help would be appreciated!).
When I looked at it there, it was then that I thought the possibility was quite strong, because of the appearance of the stonework, the windows, the roof line and the chimneys. Couple that to the shape of the building shown on the 1904 map (the photograph seems to suggest that there are two rooflines on that building, one behind the other) and it becomes more of a "runner."
You have of course to remember that the photograph is getting on for 100 years old, so there may have been many alterations/ extensions to the building in the intervening years, but the "basics" will still be much as they were back then.
In response to Andy Kirkham, although I said in an earlier post that I thought the phorographer was facing north in the morning, he could just as easily have been facing south in the afternoon/ evening. However, given the state of development of photography at the time, he (I am assuming it was a "he" - did they let women loose with cameras in those days

) would have had to be very careful in his positioning when facing in the general direction of the sun.
We also probably need to bear in mind that the purpose of taking the photograph was not to show the surroundings, but to feature on the subjects. It could be that railway infrastructure such as signalboxes may have been deliberately avoided by the photographer so that they did not detract from the main point of the photo.
All that said, I will not be putting any money on this suggestion down the bookies
