The new building, covering more than 900sq m, was designed by architects de Lisle Jenkins who have been involved with previous Southwell building projects.
"Southwell prides itself on offering an educational experience designed to inspire individual achievement, strong personal values and confidence for life. This new facility enhances the world-class all-round education further for Southwell children," the school says.
Southwell is an iconic Waikato Independent co-educational Anglican boarding and day school, for children aged 5 to 13 years, set in 32 acres of park like grounds in the heart of Hamilton City.
It is the oldest independent school in the Waikato, opening in 1911 and is New Zealand's only co-educational primary day and boarding school.
