The practice was founded by Miles Warren in 1955,[2] and with the award of the Dental Nurses Training School (now known as Central Nurses' Training School) Miles sought the assistance of his fellow atelier colleague Maurice Mahoney.
The partnership created a distinctive form of architecture utilising a modern, brutalist style (described by Warren himself as "constructivist") involving widespread use of concrete and harsh geometric shapes.
Several of their buildings in this style are now among the highlights of New Zealand modernism: Christchurch Town Hall, Harewood Crematorium, College House and Canterbury Students' Union being but a few.
[3] The style was influential within New Zealand, being a partial inspiration for Ted McCoy's Archway Lecture Theatre complex at the University of Otago, among other works.
Warren and Mahoney's designs are found in other centres throughout New Zealand, most notably those of Wellington's Michael Fowler Centre and Bowen House in Wellington and Auckland's Television New Zealand building.
