I stumbled upon this today whilst making my way from Senate House (keynote delivered! questions answered!) to the BL - somewhere in the wilds of Kings Cross, or south KingsX, in a land of council flats and cheap hotels - and this was down a dog-leg side street, and was covetable beyond words - tall, thin, plant-bedecked, and with St Pancras in the background. Given that I'd just been talking (among other things) about the allure, from the early C19th onwards, of London's hidden places that reveal themselves like little intimate secrets, this seemed amazingly timely.
And yes, it was a very, very wet day.
