Many small and useless triangles: the anti-human dysfunctionality of recent modern architecture

It would be hard for me to have a lower opinion than I do about architects since WWII; and they seem to get worse. The bad architecture of the 1950s-70s was boxy and nasty - but cheap and broadly functional. Since the 1990s, however, buildings are boxy, nasty, expensive and grossly dysfunctional. The above is an ariel picture of the new primary school, built in the latter 2000s, to replace a reasonably attractive but very badly neglected Victorian school. Both my kids attended, across years spanning before, during, and after the rebuild. Instead constructing an ugly, expensive, and badly dysfunctional design.The major dysfunctionality of this school was related to the large population of the school - 700 kids - and a small site; such that there was never much space for the children to do things outside. However, as can be seen from the ariel view; the site had the advantage of being almost square; so that a-designed-from-scratch school could - in principle - make-useful nearly-all of the available space; most obviously by building close-to and parallel-with the edges of the site. Instread, the architects (and education authority) squandered this advantage; by building much of the school at about 45-degrees angle with the boundaries; thereby reducing much of the precious outdoor space to small and useless triangles (plus other small and useless "corridors" where buildings are set needlessly far back from boundaries). So, generations of children have-had, and will-have, their already restricted outdoor space gratuitously reduced even further...And all for no good reason at all - except the whim of architects in thrall to their idiotic "fashions", and presumably the dumb gullibility/ bribability of local government officials.
