There are 8 boarding houses at Aitchison, each with excellent facilities, including dining halls, prep rooms, and common rooms. Each house proudly displays its history through photographs and trophies, marking the achievements of boys throughout our history. A boarder's journey progresses from Gwyn (Junior School) to Saigol and Monnoo (Prep School), and then to one of five senior houses: Kelly, Godley, Leslie Jones, K&N's, and Shirazi (Senior School). Life is busy with supervised homework tutorials, games, sports, clubs, and occasional outings.

The senior houses are for boys studying O and A Level and or FBISE-assessed Matric and FSc. Housemasters and resident staff oversee the coordination of daily routines, providing caring and disciplined leadership in a 'home' that boys of all ages cherish. Aitchison teachers form the basis of our regular evening tutorial programs from K1 to H2.
