.... is built with the thickness of one house brick, and is supporting a
similar wall and floorboard joists on the level above (3 bedroom 1930's
house, wall between front reception room and hallway), is it likely that
I will demolish said house by hanging 30Kg of wall cabinet on it?

How do I establish what the maximum loading is for wall cabinets and
shelves on a particular wall? I realise this is somewhat of an open
ended question. I just don't want an open ended wall...

30kg will be fine on any[1] wall. The fixings however will need to suit the
wall construction and whether the load is pulling away from the wall, or
only in shear (downwards).

[1] Even most wooden studwork walls, provided you attach to studs, not the
PB. Think kitchen wall cupboard full of plates.

If the wall is brick, no worries.

If it's breeze block or some other ash block you might need a slightly
better fixing to cope with strong pulling loads, like a TV on an arm.

What are you hanging and do you know what the wall's made of?

More than you think in a typical pre 60's house.
