Home of the British Prime Minister, Number 10’s very ordinary address and the modest terraced façade are deceptive, giving little clue to the real size and grandeur within. Number Ten in fact consists of two houses. The house, which faces Downing Street, is a typical late 17th Century town house. But it conceals a complicated building, which was re-fronted in the 18th Century and enlarged in the 20th Century. Today, iron gates at the end of Downing Street prevent public access for security reasons.
