Exiting Peckham Rye station, you’re not aware of it, but standing on the platform you can see a mansard roof with ornamental railings silhouetted against the sky like a French chateau. Designed in the 1860s by Charles Henry Driver, architect of Sao Paolo’s Estacao da Luz, it once covered a vaulted waiting room which, after an intermediate existence as a billiard hall, was closed to the public in 1962.
