So a mate says "If I brought round my Dovecot, could you mend it?"
So I thought its worth a look.
"What's wrong with it?"
"It got left outside!"
(which one would have thought was not unexpected for a bird house you are supposed to mount on a pole in the garden)
So did a bit of a post mortem on it... yup its pretty shagged beyond sensible repair. Not helped by its original builder starting with a subframe of non water proof ply, before giving it a roof that would be as effective at keeping the rain out as a colander!
So I suggested that I use it as a rough pattern, and build a new one from scratch.
Here is how it came out (and the remains of the old one):

Remind me not to make a hexagonal building again!
Mostly built from scrap - 4m of 4x2 resawn to make shiplap, and some 1" x 1.25" timber for the framing. Some reclaimed exterior 1/2" OSB for the interior partitions, floors, and roof boards, and 5 roof slates chopped up for the roof, with some real lead flashing. The finial was a cut down and reshaped part of a table leg.
