St Peter’s College has three houses:
- Bishop (red)
- Lourie (blue)
- Oriole (yellow)
The houses were named after birds that were resident in the area when the College was built.
Every student is allocated to one of the three houses, which form the basis for intra-College competition. The different houses compete on the sports field, culturally and academically. The sought-after prize is that Sir Peter Rabbit, a giant fluffy rabbit that's also the College mascot, wears the winning house’s colours for the year to follow. The Housemaster and House Captains manage each house.
