I have decided to try to get the engine shed to a reasonably completed state.
I can't actually remember what the plan was when I stated making it, but as the roof doesn't cover the whole length of the building the best conclusion I can come up with is that I intended to add a roof mounted water tank... so that is what I have decided to do...
A close up of the office end.
I need to add a lintle over the window and door, any sugestions about the best way to do this are more than welcome.
the brickwork is south eastern fine cast plasticard with a mixture of grey paint and ash rubbed over the brick card to fill in the mortar courses. The bricks were then dry brushed with a terracotta red before odd ones were picked out in lighter or darker colours and the whole thing was weathered.

Whilst I put off digging out the plastic stuff a few sections of wall are covered in other types of brick paper, this is a quick comparison of the South Eastern and scale scenes brick paper

the roof is covered in scale scenes slate paper, it is great stuff, especially if you have access to a laser printer.

The tank was constructed using card (from a cereal box)

super glue was used throughout as it enables sanding and filing to be used at a later date to smooth joins out and improve any shaping issues.
it is utterly freelance and only lightly influenced by the results of a quick google image search.

The plan for the next bit is to paint it in Humbrol #63 and cover the top with scale scenes 'roof cladding' I might at some point hide batteries and lights for the building in the water tank.
then the next jobs will be to decorate and furnish the office and build the large doors. any suggestions for reference material for those jobs would be great.
