This high-tech American car wash fits into a compact 40m long build and features a convey-belt system for pulling cars through. Also included in the design is a plant room and office.







Although we’ve constructed car washes before, Autowash is the first of its kind in New Zealand. Based on an American concept, this high-tech car wash pulls vehicles through the cleaning process on a conveyor system instead of having them drive themselves. 

Overall, the build is 7m high and 40m long,  covering the entire concrete tunnel structure. Inside is a pit that spans right through the middle, along which the pulley system sits. Adjacent to the main building sits the plant room and office.

This project began by sourcing a prime site from Calder Stewart’s land portfolio, capturing high traffic movements from the SH1/Johns Road and Sawyers Arms Road intersection. It was a complete Design Build solution, with a leaseback to the client. 

Completely automated, this American design features the latest cleaning technology and also uses a significant amount of water up to 100,000L of water per day. A water purification and recycling system was installed to compensate, reducing the overall volume of water needed.

Another unique aspect of this project was the very high level of client collaboration on-site, with scheduled day to day meetings very early on in the process. This procedure ensured an extra level of oversight when it came time to lay down the correct pipes and cables.

Regarding the ‘mechanics’ or ‘fit out’ of the car wash system, once we had a weathertight shell, the client brought their equipment, designers and engineers from the USA and Australia to cover the services side of things. Despite a tight site and complex base build, programme-wise, we delivered a clean handover for this part of the project. With good communication across all parties, the coordination of the build went smoothly. While fit-out took place in the tunnel, our crew finished the outside areas, including car parks and driveways.

To complete the small office, we trialled an aluminium vertical weatherboard system. Even though it’s traditionally more of a residential type product, it worked well with SAR’s overall look, adding a nice aesthetic touch to a functional build.
