Large format fit out solutions under one roof
Fitting out expansive retail stores isn’t just about filling a space with products—it’s about creating a skillfully crafted environment that enhances both function and shopper experience.
Did you know there are 14 key interior design fundamentals we consider when designing a large format retail showroom?
From strategic lighting and temperature control to layouts that guide customers seamlessly from the entrance to the rear of the store, every detail matters. Durable, attractive flooring, thoughtful zoning to showcase product categories, and smart integration of signage and acoustics all play a role in shaping the space.
Behind the scenes, staff areas, compliance with accessibility standards, and energy-efficient systems ensure day to day operations run smoothly.
By blending branding, sustainability, and adaptability, we create spaces that are not only visually impressive but also highly functional, giving your business the best chance to maximise your sales.

How are sustainable practices affecting fit-out costs?
Sustainable fit-outs typically add 8-12% to initial costs but reduce operating expenses by 20-25% over five years.
Key investments include LED lighting systems, smart HVAC controls, and recycled materials. Australian retailers increasingly prioritize these elements, not just for environmental impact but for long-term cost benefits and consumer appeal.
What's driving the shift toward higher ceilings in large format retail?
Modern bulky goods retailers are increasingly specifying 6m+ ceiling heights, up from traditional 4.5m standards.
This trend reflects changing consumer behaviors and operational efficiencies. Higher ceilings allow better product visualization, more efficient stock management, and reduced HVAC costs through improved air circulation.
Our projects show 15-20% improvement in operational efficiency with optimized ceiling heights.
How does AI help you deliver a project?
In the large format retail sector, AI tools enhance three key areas: spatial planning, project scheduling, and cost efficiency.
Here's a real-world example of AI in action:
For a recent 2,800m² furniture showroom fitout, Our AI models identified the best delivery dock placement by analyzing stock movement patterns in a six week period at a similar outlet. Our models processed delivery data and stock weights, redesigning the loading zone to cut handling time by 35%.
During construction, our AI technology adapted to material delays. When framing was delayed by three weeks, it recalculated tasks, bringing forward other works to keep the project on track, preserving the completion date despite supply chain disruptions.
Our AI cost management tool tracked material prices and flagged a 12% spike in material costs, suggesting pre-purchasing key components, saving $42,000 which otherwise may have been passed on to the client..
Result: The project was delivered two weeks early and 8% under budget.
Technology drives progress, and we are leading the way, pioneering Australia's construction industry.
