Spotlight Commercial Project: Lexus Showroom – Christchurch

We’re proud to have delivered the mechanical services for the new Lexus Showroom on Montreal Street – a carefully curated commercial space designed to reflect Lexus’ reputation for excellence, precision, and innovation.

Partnering with Amalgamated Builders Limited, we delivered this 572m² two-level showroom across 2023–2024, with a strong emphasis on architectural integration, energy efficiency, and refined presentation. The result is a flagship space that sets a new standard in showroom design for the South Island.
