I've always intended there to be an engine shed at this end of the layout to act as view-break, as well as some foreground interest. However the site is quite cramped, so to ensure the structure will fit and look right, I've used some cereal packet card to mock up the size and shape. This saves spending time building a structure only to wish I'd done it differently ...
Actually I've had three goes here! From left to right the shed has got 5mm shorter in length and 5mm wider with each iteration, and the height has varied too. In the foreground are some N-scale factory windows which I think will work well for this building.
This is the third iteration roughly in place on the layout, the railcar shows there is ample clearance to the "main" line, while the shed appears wide enough for maintenance to happen on the loco inside. From this angle the exit hole in the backscene can still be seen, but from a more normal viewing angle the shed hides it nicely. The shed is quite short, but long enough for the typical locos used on the layout, and anyway most of the building is hidden behind the "wing" that hides the end of the backscene so the length is not apparent. For that matter, I might not bother with the window to the right ...
The question now is what materials to build it from. I was thinking brick walls with a corrugated roof, for a reasonably substantial structure to match the station, a slate roof might give an older appearance. But perhaps a wooden structure with a corrugated roof, or a completely corrugated structure, would add a little variety. After all there is plenty of brickwork on the layout. I've also been looking for prototype inspiration, and considering putting a water tank on the roof for interest. Any thoughts?
