I started the day with a cup of coffee in this year’s Serpentine Pavilion – a lightweight and satisfyingly patterned structure designed to catch and channel water and the work of Francis Kéré, an architect from Gando in Burkina Faso, but who studied in the Technical University in Berlin and is now based there:-

Is he the first African architect to design a Serpentine? Excellent !
I think he might be. Charles
He evidently admires the underground line [U7] in Berlin designed by Rainer G Rummler of 1980-84 – memorably the setting of Claire Hooper’s 2005 film ‘Nach Spandau’
Thank you – a nicely esoteric reference: playful, decorative postmodernism used for public pleasure and benefit. Charles
