How would you achieve this?

I really like the metal fascia that sits below and above the windows, but I am unsure whether that would be done by the window supplier, or whether there is exterior cladding that is fitted using clips?

That's a spandrel panel. Our window company sourced them for us from a aluminium sill manufacturer, so everything would match.

Thanks Conor.  Sometimes, it's just the name that I needed.  I've never heard of spandrel panels.

just be sitting down when you get a price for them.

IF crazy expensive, it may not be too hard to have fabricated yourself. Assume folded aluminium, powder coated, PIR behind?

That's what our were. Steel beam, PIR, glued on. ICR ours were £900 for a 5m x 200mm length, plus two ~150mm L pieces for a couple corner posts. Same company that did the cills so colour match is perfect.

Sound like a spaniel cross with another dog.
