Studied this branch for many years and have a large library on the subject. In addition to the picture of the good shed above I have posted most of my research at https://www.flickr.com/search/?text=Dunmow%20station&sort=relevance&user_id=26359504%40N08 Took quite a time to find a picture of the other east side of the goods shed over the years. Today there are two of the west side and one of the east, including the crane, are in the new edition (only) of Peter Paye's book on page 175. There is even colour 8mm film of the branch including goods shed detail somewhere out there as I saw it once in Witham at Stour Valley RPS. BTW Lavenham goods shed was similar to Dunmow I believe.
As for the brick colour differences, that is an interesting subject for me as I do believe that the bricks for Dunmow viaduct were made in Dunmow! I saw the imprint on the brick's frogs. It looks as though local brickworks at Braintree (very close to the station), Dunmow and others along the line supplied local produce?
CDC Street Level models do offer some basic card kits for 1865 standard GER buildings similar to those at Dunmow. http://cdcdesign.webplus.net/mainline.html
There were a few plans and one to connect from Ongar through Dunmow and Great Bardfield to join CVHR at Yeldham... Plenty of scope for imagination there!
Let me know if I can look up anything for you all or if anyone has pictures of the Banana Factiry at Easton ;-)
I am building a course scale layout planning to capture the atmosphere and several features of the line including Cressing.
