Dorset Street Flats
The Dorset Street Flats in Christchurch were designed in 1956 by architect Sir Miles Warren as small-scale owner-occupier flats. They were built to a modernist, new-brutalist inspired design whose key innovation was the use of load-bearing concrete block. The style became known as the “Christchurch School” which challenged and influenced the work of other architects. The buildings are recognised as a Category 1 historic place by Heritage New Zealand.
In the Canterbury earthquakes the complex sustained major damage. After an insurance settlement the owners still had a significant funding shortfall and residual structural weaknesses.
Heritage EQUIP funding will support upgrade work that includes:
- addressing the capacity of the ground and first floor concrete block walls with shear walls and associated ground beams
- replacing unreinforced concrete block with timber framed walls in some areas
- establishing a plywood diaphragm at roof level
- establishing transfer trusses to ensure new shear walls and diaphragms deal with earthquake loads appropriately.
