Commercial Interior Designer Brisbane CBD
High-end commercial interior design built for Brisbane’s most ambitious businesses
Brisbane CBD is one of Australia’s fastest-growing commercial precincts—home to premium workplaces, blue-chip companies, national health providers, boutique hospitality venues, and retail destinations that demand exceptional design and precision execution.
Leithal Designs specialises in creating commercial interiors that elevate brand presence, enhance staff and customer experience, and respond to the unique constraints of CBD tenancies—from heritage buildings and multi-level office towers to compact hospitality footprints and complex compliance requirements.
Led by Principal Designer and QBCC-licensed commercial building designer Sonia Leith, our studio delivers commercial interiors that combine luxury, functionality, compliance, and brand expression into beautifully resolved spaces tailored to Brisbane’s city environment.

Our Commercial Interior Design Process
1. Discovery & Strategic Direction

We explore and define the design vision through:

This stage lays the foundation for the entire project.

- engineering coordination
4. Certification & Approvals
Our studio prepares and manages the required documentation for:
- Development Applications
- Construction Certificates

- fire, mechanical, acoustic and accessibility requirements
5. Tender & Builder Coordination
Each project is competitively tendered to three builders, ensuring transparency and value.
