The historic former headquarters of lingerie company Berlei, standing in the way of the $500 million-plus SkyCity International Convention Centre, will be gutted and only its facade will remain.
Berlei House, also known as Nelson House, fronts Nelson St and Wellesley St and was the second-largest building of its kind in the Southern Hemisphere when it opened in 1931.
SkyCity plans to knock down virtually all the old structure, leaving only two exterior walls.
Consultants Boffa Miskell prepared a heritage impact statement on the old art deco factory which has Heritage New Zealand status as a category two historic place.
That report shows most of the building will be bowled and only exterior walls will remain.
