In More London, few steps away from the City Hall.Where abouts in London was this taken.
dekeyboy & crazyp thanks for your critics.
I think the choice of subjects is relative to culture and environment. These structures are uncommon for me (I live in Corsica where architecture is regulated by law and must be of traditional style). Unaccustomed to this kind of architecture I took it as a real subject, but you are right, with a step back it's more a graphic juxtaposition of volumes and materials rather than a real subject.
