London's smallest house - 10 Hyde Park Place.
Dead right - the smallest Restaurant in Amsterdam is built between two buildings as is the Smallest house in Conwy. And 10 hyde Park Place is the smallest in London.
10 Hyde Park Place
The smallest house in London is barely a metre wide. Perhaps built to block a right of way through to St George's graveyard, and hence deter grave-robbers, it dates back to 1805 and is now part of Tyburn Convent. The tiny house was actually hit by a bomb in 1941, during World War II.
