This church uses a combination of moulded decorative bricks, and lots of plaster. The creation of the vaulting would be as per any other roof with less geometrically dramatic ceilings.

I guess to be fair, they’re rather well paid, in order to fund the mortgage on their expensive property that their line manager refuses to give them permission to visit.

And if the platform collapsed, the four corners of the roof would at least be saved! πŸ₯΄

A scene from a film showing the back side of a plaster and lath wall.  It's a set prop and has been installed the wrong way up, so the plaster 'rivets' appear to defy gravity and point upwards

I think someone’s being a little bit disingenuous here. That that’s not a normal day in London. It looks like the end of a festival or something.

There is a phenomena where thin slabs of natural (and reconstituted) stone cladding expand as they become heated from sun and solar gain

They contract, expand, contract... repeatedly

Eventually they stop contracting. Restricted spaces (eg bedded in hard mortar) cause them to 'belly' in the centre

No, I did not think they were PV. When I was growing up, they called these solar panels as a very generic term because they’re panels, and they use solar energy. Yes, it’s the heat water.

It's obviously (a lot) less efficient, so you want to argue for efficiency first. There are a god number of options out there now for most roofs.

String cornices on buildings are not architectural fluff.

Note on this (somewhat neglected) building how some of the old limewash still remains.

Yep. The only thing that could make it worse is if it contains asbestos which wouldn’t surprise me, in hindsight.

Another example is this bookshop which used to be a butchers. The sign says β€œancient butcher”. Which I think means traditional more than literally β€œancient”.

I think these were popular all over the world, but they were especially popular in Italy, and still are.
