Dear Rich,
This is the nest of a solitary Bee that has been provisioned with pollen to feed the developing larvae.  We suspect it is a Mason Bee Nest based on this image on Warren PHotographic.  Solitary Bees are not aggressive and this nest poses no threat to your mother in law.

Thanks Daniel!
And thanks for the speedy reply!
I’ll let her know. She’ll be relieved it’s not a wasps nest.
All the best to you and your team.
