Demolition of st elmo courts
History
The site of the building, on the corner of Hereford and Montreal Streets, was occupied by the St Elmo Boarding House. It was advertised as "superior private accommodation". A replacement building, St Elmo Courts, was designed in 1929 by B. J. Ager. This reflected a movement in the larger New Zealand cities in the 1920s and 1930s for apartment living. The appeals were inexpensive living in a central location, with apartments offering modern conveniences and built in furniture. St Elmo Courts was constructed in 1930. Accordingly, St Elmo Court provided bedsits and two-bedroom apartments. Many of those were later converted to office space.
After the 2010 Canterbury earthquake, the building was yellow stickered (meaning restricted access only). The building's owner and his insurance company agreed that it was too damaged after the 22 February 2011 earthquake for it to be saved. Demolition began on 20 March 2011.
Structural design and failure mechanism
St Elmo Court had a light reinforced concrete frame that was infilled with masonry. Following the 4 September 2010 earthquake, diagonal shear cracks were visible in the façade in the vertical piers. One column had a shear failure. The damage became more extensive in the 22 February 2011 earthquake.
Rebuild
A modern, 5-storey replacement has been constructed on the Hereford Street site. The new building is to 180% of the new building code, and features base isolators. Law firm Wynn Williams has taken naming rights and the building is now called Wynn Williams House.
Heritage listing
On 26 November 1981, the building was registered by the New Zealand Historic Places Trust as a Category II historic place, with the registration number being 3133.
