Situated on the second level of the building, the carwash is one of the first in the world to be built on a suspended floor, providing waterproofing and detailing challenges for the construction team.

Water for the carwash is drawn from six 136,000 L underground concrete tanks (with a total capacity of over 800,000 L), which store water from the roof. The tanks were poured in situ and backfilled.

The project has also delivered highly detailed car display areas, car parking and storage on the second and third levels, as well as a service centre and office space. Two lifts have also been installed.

Full height structural glazing was installed on the West Terrace frontage. Measuring 7 m high x 2 m wide x 25 mm thick, these glass panels are restrained by billets suspended from the second floor to present a solid glass appearance.  This is thought to be the first application of this sized glass in Adelaide, and was a logistical and construction challenge for the project team.

The client engaged their own contractors to install some of the vehicle servicing equipment, and Built Environs also integrated and managed these activities within the construction program.

The construction methodology also had to take into account overhead powerlines on two sides of the site, a building plan that extended to the boundaries of the site, and heavy city traffic on three of the boundaries.
