Tim Lamb brought next idea :
Friedland's 100m range one. A bit expensive, but very reliable once paired they stay paired. I used them on numerous banks, in electrically very noisy environments.
But I'm sure an experienced engineer such as yourself makes sure the batteries are replaced as needed. Which doesn't seem the case with many wireless ones. Given how many times I find them not working.
However, if you really do need one to take into the garden, easy enough to add to a basic wired system. And have the good points of both.

Nearest front door is about 20m and they have a wired one. Benefit of rural dwelling. Downside is no one is likely to hear a burglar alarm at the permitted volume.
Trouble is our Greenhouse is 50 m from the house - rather a lot of cable.
Assuming you can't already buy one for the job, wire a cordless push to the wired doorbell circuit via a relay? Or even just arrange for it to be powered up from the volts?
I graphed a ATTiny85 microcontroller into my Freidland Westminster Chimes, and now it plays all four quarters instead of just the regulation third & fourth
I'm going to use another of the spare pairs to the front door to run an audio feed. Glass speaker above the door.
I have Westminster chimes but I'm going to 'ring the changes' and provide a way of changing that from any phone. I'm open to ideas for other audio.
(this is only for the benefit of the caller. They might hear the phones ringing but believe the doorbell has not operated).
That is a bit of a problem, the chime isn't that loud, and even in this quiet suburban street, the caller is hard pressed (a pun!) to hear it.
Nah employ a butler, plenty of cheap foreigner workers about, they can clean cars too.
Resident dogs are usually very good at announcing callers. (Four legged ones).
Fit on the external wall (assuming cavity) and feed cable up into loft or void or whatever is above through cavity.
Or in the case of my neighbours, every time someone uses their keyfob to lock/unlock their car :-)
Door knocking sound? ;-)
Dog barking.
"Ring a Ring o' Roses"
Lion roar.

Perhaps. Timber frame so cavity ok.
One of my insulation jobs was to put 100mm PIR foam bats between the truss uprights creating storage areas. Removing some of those should allow me to reach the outside walls.
I am rather tempted by the *plug in* versions as the only battery would be in the push button.
Westminster chimes would be no good for us - we are too used to hearing them and ignoring them, as our living room clock (wind-up type) chimes the hours and the quarters!

I bought a wireless bell that has 2 sounders that run on mains. The push is a kinetic one, rated at IP55 and is stuck on the door. No screws but, judging by the way that it seems to be stuck down, would be a pig to get off.
I think you mean 'phrases' not 'quarters', of which there are five, each played twice an hour - the mechanism makes two revolutions. The linked video plays the four phrases that make up the hour chime.
I could always trigger a Bell 80D, I suppose. Right next to their ear.
but at 13 quid a time you can just dump it and buy a new one when the basic model you buy stops working

Oh boy does that annoy me
