HMS President (1918) , formerly HMS Saxifrage, is a Flower-class anti-submarine Q-Ship completed in 1918, and is one of the last three surviving warships of the Royal Navy built during the First World War, (along with the 1914 Light cruiserHMS Caroline in Belfast, and the 1915 Monitor HMS M33 in Portsmouth dockyard).
The average single-family home built today is 2,657 square feet, more than twice the average single-family home built in 1920. To determine how homes have changed over the past century, 24/7 Wall St. estimated the size of a newly constructed single-family house between 1920 and 2014.
A family home in the report is defined as one in which a couple or a single parent lives with at least one child who is under the age of 18. Overall, the average family home has shrunk from 98.8 square metres in 2003 to 96.8 square metres in 2013, according to the report, based on official figures and its own research.
