We're looking north with the entrance to the Red Gates station on the right. The building up ahead has been replaced now and is #28. The concrete building on the left is still there, #3.
In the Flickr/Yahoo aerial imagery shown in 2011, the small building on the left was still there (now a patch of grass), and the new building that replaced the house was still under construction. Thanks to Flickr user mixtara for figuring out the location.
