Ashford's finished.

I decided to add a small boilerhouse to fix the smokestack to and used some spare wall from the kit.  I wanted to add a small window to add interest so I cut down one of the left over windows and ended up with the curved top and one row of panes.  I then sliced off a curved brick lintel from a spare window using a fine razor saw held flat against the plastic. I marked out the hole and drilled, cut and filed till I got a good fit.  I painted the boilerhouse to represent blue engineering bricks.  After fixing the boilerhouse and chimney there was an unattractive gap behind so using bits of walls from my scrapbox I made a curtain wall to fit. That's it.
