I gave up on Euro cylinders and went with conventional sash handles in the end, with a "normal" keyhole but at least I shouldn't have any security concerns with a regular BS sashlock. I did get 2 swingy escutcheons though - one for inside and one for outside, which between them ought to do the job without looking too odd.

The handles are wrought iron and so are the escutcheons so as long as I can fit one to the other then should be a breeze. Or stop the breeze, more to the point.. I was considering a strip of black rubber with a slit cut in it to put under the escutcheon on the side that a key is not normally used on - ought to make a difference too, but I'm not sure how much leakage a keyhole makes in the overall scheme of things.. I'm not sure if I am chasing for holes the size of 5p or a dinner plate...

What's the solution for this sort of lock? All of the escutcheons I have seen need to be affixed with wood screws.

OMG. I’d forgotten the blasted key holes, so no cat flap, no key holes and no letter box. Airtight construction is a cruel mistress. Trust GBF to solve these testing issues. Blue tack for the keyhole, a doorbell for the cat and an upturned bucket for the postie?

A post box on an outside wall next to the front door is as good as a letter box. Gone are the days when people ran downstairs in their pyjamas to see what the postman had delivered. You're lucky if he arrives before lunch these days & checking a postbox when you come home from work is no less convenient.

As well as improving airtightness, it also avoids the risk of someone posting something nasty or flammable through the letterbox!

Drill a hole and use a short self-tapping screw.

Do you have a very small postie? :)

They are all short down here, or is it that they all wear shorts. Seems to be the latter.

Post box on the outside seems sensible, except my parking is arouind the back and I sometimes don't open the front door for months. Made the positioning of the burglar alarm and the light switches a complete nonsense.

I believe euro locks are a bit more airtightn no gaping hole right through the door (and the keys are smaller in your pocket)

A(n expensive) solution for the cat flap:

Look at the video with a candle and a leaf blower:

I have one, but it's waiting for the house to be built to find out how well it works.......

to be sure he won't take grateful pee-relief?

A tunnel thro wall with catflaps both ends, of the old type that hold tight-shut with magnetic strip all round perimeter (fridge door principle) is my best hope so far. That is, in preference to the simpler brush-seal type, which is v soon standing open a crack, what with all the cat-brylcreme they accumulate. Takes a bold cat tho. Also serves as postbox.

What a friend did and appears to work well (well their cats are not bothered, well they do have a cat electric blanket to sleep on (quite an incentive to come in!) - yes they really do, crazy I know

I have just done about 10 of these and the nasty brass-plated metal was remarkably resistant to my drill bit! I used epoxy. Of course you can't do it in situ unless you want to stay and hold it for 15 mins, but I did a 'batch' at a time and by the time I'd finished the last, the first handle was more-or-less ready to re-fit.
