Wedged between key civil infrastructure and a busy arterial road, Site 9’s Wellington waterfront position had challenging height restrictions which required a unique and complex design.

Low-rise and base-isolated for superior seismic resilience, Site 9 features a unique out-of-ground seismic plane located underside of Level 1. The site’s height restrictions meant that a three-storey building was the most likely option but with careful co-ordination, the project team delivered a four-storey building.

There was just 50mm between the ceiling and structure beams, so every pipe, cable and duct penetration had to be carefully planned to ensure services’ runs were achieved and costly alterations to steelwork were avoided.
