Manning designed one of the first Ludwig Mies van der Rohe style skyscrapers built in New Zealand,[7] the AMP Building (1962 – Thorpe, Cutter, Pickmere & Douglas) on the corner of Queen and Victoria Streets, Auckland.
The Majestic Tower rises from Boulcott Street and is very prominent, especially at night when its horizontally spread fan of metal rods tipped with powerful light bulbs is illuminated.
The street frontage incorporates five distinct buildings: the Edwardian façade of Preston Meats; a newly inserted three-storeyed building of no particular quality; the massive central entry topped with a metal and glass canopy; and a flat granite surface glazed above, which finally slopes away to Dr Henry Pollen's House designed by William Turnbull whose style is exuberantly French Empire but built in wood.
On Willis St, granite colonnades, ended before Turnbull's house and leading to shops behind, providing pedestrian shelter along the frontage.
[10] The School of Music (1980) (designed with David Mitchell) represents a departure from the Brutalist norm of that period,[11] although in a completely different post-modernist style.
