Be careful of using double sided tape- with some brands or most the glue drys out over time with the lamination coming free. PVA or paper glues would be a far better deal.
The edges can be covered with printed corner trims to walls and openings, with fascia & barge trims to the roofs
I agree with Darius43 about 'flat' corrugated roofs.
Take a look at Kevin Sweeney's thread for his building builds!

Cutting edge stuff
The WW Kit provides outer frames in the etches, but does not include frames for a chassis. Most builders, but not all, use a 'spud' or Blackbeetle motor bogies for power so all that is needed is a cross support to mount the bogie off.......

With recent requests for Class 800 drawings I post below KMCE's scanned drawings in pdf format. It was Ken's intention to complete out a general arrangement set of drawings and make them available to fellow modellers, sadly time ran out for him, but with these drawings he will be remembered.
