Greenbank House was opened in 1997 as an overflow House from the other three Day Houses with just 70 boys and has since grown to 109 in 2010. Over the past 12 years it has developed its own traditions and routines and has consistently been one of the top all-round Houses in the school.
The motto, Semper ad Optima, challenges every Greenbankian to always strive for the best.
