One of the homes in Windsor Terrace went on the market for £2,000,000 a few years back. This is the closest I've been to it, right at the end of the private road. Presumably they're okay with people wandering down the road if there's a blue plaque to be seen at the far end?
Both the plaque to Edward St John Daniel and the other photo I took (in these early walks I was mostly walking, rather than mostly taking photographs) have interesting stories of a rise and fall associated with them in the first Google hits I found. Daniel was indeed the youngest recipient of the VC, but was stripped of the medal by Queen Victoria herself in 1861, following conviction for desertion and evading court martial. Lubetkin is probably most famous for designing the penguin pool at London Zoo, which was closed 17 years ago, after the micro-abrasions in the penguins' feet caused by the concrete led to them developing an infection with the charming name "bumblefoot".
