At a glance

Affected location: Waltham Forest

Illustrative image: The main entrance is very grand indeed. The rear extension was built somewhat later than 1938 - perhaps very early 1960s, a vanishing period of British architecture. By 2013, a retrofit, modernising and adding cladding had occurred www.bbc.co.uk/news/business-25298461 — sludgegulper/Wikimedia Commons, CC BY-SA 2.0
