Working with the past can throw up surprises, as the Haydn and Rollett team involved in this commercial project in Pukekohe learned. As well as building a new showroom for Toyota, they were tasked with partially demolishing and repurposing a neighbouring warehouse into a workshop for the dealership, complete with a seismic upgrade. Early on, it was discovered that the existing structure was not up to snuff and had to be remediated. Being located alongside the main trunk line, there was also a need to insert significant piling deep under the existing floor, an awkward and time-consuming process.
