The model is a slot-together laser-cut MDF kit. Nothing exciting here, but the roof is very well supported and that is the sort of job that pre-cut parts make easy. I wouldn't have put this many ribs in if I'd been scratchbuilding, but if the pieces are there, I'm going to use them.
Laser-etched detail doesn't cut it for me however, so strips of Plastikard were superglued in place and slices of microrod stuck on these. It might be a bit overscale, but my garden railway style is cartoony, so they look the part. I like to think I have over-emphasised the detail for dramatic effect.
The roof is plastic glued and pinned down because I didn't trust it to stay put. Over this, some tissue paper is fixed with lashings of plastic cement.
