Flower’s House began in the early Headmaster’s House with the appointment in 1910 of Arthur Edward Flower as Housemaster.  Flower came from Kaikoura to Christ’s College as an Upper Form II boarder in the second term of 1886 and left in 1892 having been Head of School and the holder of various Scholarships.  He went to Canterbury College and completed a BA in 1895, MA in 1896, BSc in 1897, before returning to College as an Assistant Master in 1897.  He completed his MSc in 1906 while teaching.

In 1919 he and his family moved across the road into the wooden part of the previous Flower’s House (Ross House) while the adjacent building (always previously thought to have been designed by Cecil Wood, but research shows to have been designed by Samuel Hurst Seager)  was completed.  It was originally named Bowen House, after Sir Charles Bowen, a fellow of Christ’s College, but colloquially it was always “Flower’s House” and this became official in 1933.

The 1919 Flower's House and Ross House were  demolished in 2004 and replaced with the current Flower's House, designed by Alec Bruce, a great nephew of A E Flower. The Master's  House, which  was moved from the Music School end of the grounds, to the Rolleston Ave- Gloucester Street Corner as part of the Resource Consent, was destroyed by fire.

The hung fleece which the House has adopted can be seen in the College Crest, but the College Crest took it from the Arms of the Canterbury Province.  It is a reference to the importance of  pastoral farming in Canterbury.  The motto Fiat Floriat translates as “May he flourish”.
