Thanks Rick, I'm having fun learning, so while it may never be a masterpiece it should hopefully be a good foundation for future projects.
As for the plumbing, I'm having to rein myself in a bit. I have a list of things in my head that I could add, but with my low attention span, if I start them all I'm pretty sure I'll run out of steam before the whole thing is finished. Would rather do a quick sweep as it were of the main things, then, as you say, add extras at a later date if I'm still interested.
Some of the things I have in mind:
plumbing
better tap/faucet
"paper" holder
loo brush
cleaning products
mop & bucket
waste bin
towel & holder
soap / hand cleaner dispenser
wedge to hold door open
drag marks on floor where sagged door has caught it
cobwebs
stained tiles/grout
magazine / newspaper
light fitting
hidden 10mm socket/spanner (motor trade joke)
And that's without really thinking about it lol. If I multiply that by the whole building and exterior, I'd be at this for years, which I know I don't have the staying power for. I'm already itching to get on with the next project!
Paul - I'm trying to make it a bit neutral if I can, so that I could display either military vehicles & figures in there, or civvy ones at a similar scale. I'm already wishing I'd made it bigger, but have another board the same size that I could use in the future to extend it in a modular fashion, whilst keeping storage size down.
