When embarking on a new build or renovation project, one of the most common questions we get at LTAA Architecture is, “How do architectural fees work?”
As architects based in New South Wales, we understand that every client wants transparency, predictability, and value for money when investing in architectural design. That’s why we use a hybrid fee structure, combining fixed fees with hourly rates. This approach not only provides cost clarity but also ensures flexibility, fairness, and quality results for your project.
Here’s why our fixed fee + hourly rate model is the smart choice for your residential architecture project.
1. Clear Cost Expectations with Fixed Fees
Our fixed fee component gives you clarity and confidence from the start. Based on the scope and complexity of your project, our fixed fees typically range between 3.5% to 8.5% of the estimated construction cost.
This covers clearly defined stages such as:
Concept Design
Design Development
Planning/DA Submissions
Construction Documentation
By locking in fees for these key phases, you’ll know what to expect and can plan your budget accordingly—without surprise costs creeping in. To have a better understanding of our process please click HERE for more information.
2. Flexibility for the Unexpected with Hourly Rates
No two homes—or clients—are the same. Sometimes, additional design changes, extra consultant coordination, or unforeseen site conditions arise. Rather than inflate our fixed fees to cover every possible contingency, we apply hourly rates only when extra work outside the original scope is needed.
This approach gives you:
-
Greater control over additional costs
-
Transparency in how and why extra time is billed
-
Flexibility to explore design options without committing to a whole new contract
It’s a fair and honest system that allows your budget to go further, while still accommodating the design flexibility many clients want.
3. More Value, Less Waste
A combined fixed and hourly fee model ensures you only pay for what you need. At LTAA Architecture, we tailor our services to match your unique goals and site conditions—whether you’re building on a steep block, a coastal site, or a bushfire-prone area in NSW.
By keeping the fixed fee portion lean and using hourly rates strategically, we can focus on delivering value, rather than padding out fees “just in case.”
4. Transparent and Tailored Architectural Services
We believe in building strong, collaborative relationships with our clients. Our hybrid fee model reflects that philosophy—it’s built on mutual trust, shared goals, and open communication.
