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.
For instance, an average size house is 1,500 square feet, but the roof could be up to 2,100 square feet. Itâs typical to add on an additional 10 percent for waste on a simple roof project and up to 15 percent for a more complex and complicated installation job.
