St Andrew's College boarders have returned to a new $15.2 million complex, after almost two years of boarding in Christchurch motels.
Two of the college's three boarding houses were demolished because of damage from the February 2011 earthquake.
The construction of the two boarding houses, designed by Wilkie and Bruce Architects, was completed in 13 months.
The structures sit atop significant ground remediation work, comprising of 660 stone columns, six metres deep, overlaid by a deep gravel raft and concrete slab foundation.
The older boarding house, not demolished in 2011, underwent a $2.2m refurbishment and earthquake strengthening.
General manager David Evans said safety of pupils and staff was paramount.
"The total team effort between our architects and our contractors Mainzeal has been amazing and they have met some very challenging deadlines that have allowed us to be open within 13 months of starting construction."
The new complex is designed with striking landscaping.
Every floor has a day lounge, complete with television and balcony where pupils can relax.
