The Kohimarama & St Heliers project necessitated fresh thinking to rebuild the eroded beach and vulnerable seawall along Tamaki Drive while preserving the iconic Pohutakawa trees.

The design is an award winning scheme that transformed Kohimarama Beach into a premier destination for beach goers. The naturalistic rock headlands were the first of their kind and have become a part of the Tamaki Drive coastal landscape. The solution diverted storm water to either end of the beach and piped it out to a rock shelf. The rock headland formations were hand shaped and coloured to match the surrounding cliffs and recede into the existing environment. This innovative and cost effective solution, elegantly solved the problems of protecting Tamaki Drive from the encroaching sea and has become an integral part of Kohimarama’s unique appeal to residents and tourists.

To complete the beach refurbishment, a timber boardwalk was added to enhance the foreshore esplanade reserves. This design has transformed a previously degraded coastal landscape into premium sandy beaches that give the community an enhanced coastal lifestyle and provide a visitor experience that is second to none.
