Designs Grounded in Local Knowledge & Best Practice
With decades of experience designing for Brisbane and the Gold Coast, our team understands the unique demands of South-East Queensland’s climate, lifestyle, operational needs, and planning context.
From materials and lighting performance to circulation patterns and durability, every detail is crafted to reflect how people work, gather, and interact in this region.
This ensures your space is not only visually impressive but also practical, sustainable, and long-lasting.
Discovery & Vision
We begin by gaining absolute clarity on your project through detailed discussions, user analysis, and operational insight.
This may include:
- brand and culture mapping
- business workflow review
- spatial challenges
- compliance considerations
- future flexibility or expansion
This stage defines your design direction with intention rather than assumptions.
Research & Spatial Strategy
Our team studies:
- tenancy or site conditions
- operational requirements
- circulation patterns
- functionality for staff and clients
- adjacency and zoning
- brand experience touchpoints
This becomes the foundation of your spatial design framework.
Concept Development
We translate the vision into a presentable concept package, which may include:
- spatial diagrams
- preliminary floor plan layouts
- visual language and palettes
- materiality and finishes exploration
- lighting direction
- furniture themes and joinery concepts
- brand integration and emotional cues
The concept package creates a unified direction that guides all future decisions.
Refinement & Alignment
We review the concept collaboratively, refining:
- key spatial elements
- functional adjustments
- tonal or material shifts
- compliance requirements
- accessibility considerations
This ensures everyone is aligned before documentation begins
Pathway to the next stage
Once approved, the project transitions seamlessly into detailed documentation, feeding directly into your:
- Development Application (if required)
- Interior Design Documentation
- Construction Certificate
- Tender and builder selection
- Process & Construction
This continuity is one of the reasons premium clients choose Leithal Designs for end-to-end commercial projects.
The Leithal Designs Difference
Led by a QBCC-licensed commercial building designer
With more than two decades of experience across complex commercial environments, Sonia brings a multi-disciplinary edge to concept development. This uniquely positions the studio to produce concepts that are:
- architecturally coherent
- buildable and technically grounded
- responsive to commercial compliance
- aligned with engineering and services requirements
The result is a concept design that maintains its integrity through documentation and construction.
A values-based, collaborative approach
Every concept design begins with understanding:
- your operational needs
- brand expression
- user flow
- compliance considerations
- future growth or flexibility
- emotional and experiential goals
This collaborative process fosters clarity, reduces assumptions, and creates a design direction that feels both personal and commercially intelligent.
SEQ local insight that shapes better spaces
Brisbane’s climate, commercial regulations, tenancy conditions, and development context all influence early design decisions.
Our deep SEQ knowledge enhances concept outcomes through:
- climate-appropriate materials
- light and ventilation considerations
- local compliance pathways
- future-proofed spatial planning

Sustainability as an elevated design feature
Modern luxury design embraces sustainability not as an add-on, but as a defining principle.
Throughout the concept stage, we explore:
- low-energy lighting
- long-lasting materials

These elements help shape commercial spaces that feel refined, grounded, and built for longevity.
