Front, back, no sides

First of all, if these are becoming boring please tell me.  It's a record of what I've done today but I can easily whiz outside and photograph a cat - or a flower - if you're becoming bored.

Started the front panel but it's taking a bit of working out so here is my second attempt.  Single storey Scottish buildings in the Argyll region (and elsewhere) all seem to share a common footprint but this one doesn't.  It's very close but on detailed inspection, counting tiles and planks and converting known measurements for doors and window glass this one is marginally oversize.  

I wasn't going to replicate the Dalmally Hospital but I'm getting my teeth into it now so I think I'll have a go.
