German term (edited): aufgerissenen Glasfassaden

Irregular, interspersed, etc. doesn't make sense to me.

A dictionary definition of "aufreißen": vt BAU break open, rip, scarify.

That's a scary thought for a glass facade!

Karin is right, we are talking about a 'poetic' usage of 'aufgerissen' here. Judging by the phrase 'Das konstruktive Rezept ist so simpel wie schön' - this is not a jagged or split or ripped open or irregular facade.

I think the idea here is that the light superstructure is supported by pillars thus creating an expansive, elegant, airy, spacious open etc. impression - probably due to a lot of glass in between those Stützen. ;-))

The facade is virtually wrapped in glass, so to speak!

This facade is "wide open" = aufgerissen... to let in plenty of light.

My interpretation is inspired by Teresa Reinhardt's translation of "auf Stützen aufgelöst" - which also describes an elegant glass structure supported by pillars. See: http://www.proz.com/kudoz/1726296
