When embarking on the exciting journey of building a custom home or undertaking a renovation, one of the most crucial decisions you’ll need to make is choosing the right professional to bring your vision to life.
Whether you’re renovating your existing home or building from scratch, the question often arises: Should you hire an architect or opt for a design-build firm? Both choices offer unique advantages, but understanding the differences can help you make an informed decision.
This guide will compare architects and design-build firms in Australia, explaining their roles, processes, benefits, and challenges to help you choose the right fit for your project.
Let’s get straight to the point
When building a custom home or renovating, choosing between an architect or a design-build firm depends on your needs.
Architects focus on design and compliance, offering independent expertise but often requiring additional project management and separate contractors. Design-build firms handle both design and construction, offering a streamlined process with fixed pricing, clearer budgets, and quicker timelines.
If you want full control over design and specialist input, go with an architect; if you prefer a seamless, cohesive process, a design-build firm is likely the best option.

What Is the Difference Between an Architect and a Design-Build Firm?
While both architects and design-build firms are responsible for designing and planning your home, their approaches to the process differ significantly. Here’s a breakdown of each.
What Does an Architect Do?
An architect is a licensed professional with expertise in design, construction techniques, and spatial relationships. Their primary role is to transform your vision into detailed plans while ensuring compliance with building codes, safety regulations, and aesthetic considerations.
In Australia, architects must be registered with the relevant state or territory architect registration board, ensuring they meet high professional standards. Architects are trained to:
- Create Detailed Plans: Architects design the layout of your home, including room placement, window and door positioning, and overall flow. They also account for Australian climate considerations, such as natural light, ventilation, and energy efficiency.
- Ensure Compliance: Architects ensure that your design meets local zoning laws, building codes, and safety standards, which can vary between states and territories.
- Consult Experts: Architects may work with structural engineers, interior designers, and other specialists to refine their designs.
- Monitor Construction: In some cases, architects oversee the construction process to ensure the design is being executed correctly, but they typically don’t directly manage the build.
However, architects don’t handle the construction themselves. They usually collaborate with a general contractor or design-build firm to execute the project.
What Does a Design-Build Firm Do?
A design-build firm offers a more comprehensive approach by managing both the design and construction processes. In this model, the same team handles everything from conceptualisation to the final build, which can lead to a more seamless experience.
A design-build firm in Australia will typically:
- Offer a Full Range of Services: From initial concept and design to obtaining permits, procurement, and construction management, design-build firms oversee the entire process.
- Promote Efficient Communication: With a single team handling the project, communication is streamlined, and issues are addressed quickly, minimising delays.
- Provide Cost and Time Predictability: Design-build firms can offer more accurate cost estimates and timelines since they control both the design and construction aspects of the project.
- Focus on Quality and Continuity: Design-build firms ensure that their designs are well-executed by the same team that created them, resulting in higher-quality outcomes.
Key Differences Between Architects and Design-Build Firms
While both architects and design-build firms play important roles in the planning and execution of custom homes and renovations, there are distinct differences between the two.
1. Fragmentation vs. Cohesion
One of the most significant differences between the two is the level of fragmentation in the project. Architects typically create the design, but the construction is handled by a separate contractor. This can introduce more complexity, miscommunication, and delays due to the involvement of multiple parties.
Design-build firms, however, manage both design and construction, resulting in fewer parties involved and a more cohesive process. This often leads to smoother communication and fewer potential delays.
Architect Pro: Architects handle the bidding process, which ensures competitive pricing from various contractors.
Architect Con: The need to manage multiple contractors and suppliers can result in complexity and delays.
Design-Build Pro: The same team handles both design and construction, reducing the risk of miscommunication and errors.
Design-Build Con: Trust in the design-build firm is crucial, as they oversee all aspects of the project.
2. Miscommunication and Coordination
Miscommunication can often be a challenge when working with architects, especially if they are not managing the construction directly. Architects liaise with contractors, subcontractors, and suppliers, which can lead to gaps in communication and delays in the execution of the design.
Design-build firms eliminate this potential issue by overseeing the entire process. With all team members working together, coordination is simplified, and any issues can be addressed promptly.
Architect Pro: Architects ensure the design adheres to regulations and design principles.
Architect Con: They don’t manage day-to-day construction, so coordination may suffer when third-party contractors are involved.
Design-Build Pro: Clear communication is facilitated as one team handles both design and construction.
Design-Build Con: With fewer external checks, it’s essential to choose a trustworthy firm.
3. Project Management
Architects may provide some level of project oversight, but they typically do not manage the day-to-day construction tasks. This can leave a gap in the daily management of the build, requiring you to hire an additional project manager or general contractor.
Design-build firms, however, include project management in their services, overseeing everything from procurement and scheduling to construction and final inspections. This all-in-one service ensures that your project stays on track and is completed on time.
Architect Pro: Architects ensure your design is accurate, safe, and up to standard.
Architect Con: Architects typically do not manage construction directly, which may require additional project management.
Design-Build Pro: Design-build firms handle all aspects of the project, including detailed project management.
Design-Build Con: You must place full trust in the design-build firm’s management capabilities.

4. Costs and Budgeting
Cost control is another area where architects and design-build firms differ. Architects usually charge a fee based on a percentage of the total project cost (around 15-20%). This often leads to separate costs for design and construction, which can sometimes result in unexpected price increases as the project progresses.
Design-build firms typically provide a fixed price for both design and construction. This ensures you have a clear understanding of the full cost of the project from the beginning and can avoid the surprises that sometimes arise in a traditional architect-builder model.
Architect Pro: Architects offer independent expertise and flexibility to choose separate contractors.
Architect Con: The costs can add up with separate fees for design and construction, and unexpected costs may arise during the project.
Design-Build Pro: Design-build firms offer fixed pricing, which simplifies budgeting and reduces the risk of unexpected expenses.
Design-Build Con: Less flexibility in choosing contractors or suppliers, as the design-build firm manages all the services.
Which Option Is Best for Your Custom Home or Renovation?
The decision between hiring an architect or a design-build firm depends largely on your project’s scope, complexity, and preferences. If you are embarking on a large-scale renovation or custom home build, a design-build firm might be the right choice. Here’s why:
- Streamlined Process: A design-build firm offers a one-stop shop for everything from concept to completion, ensuring smooth communication and coordination throughout the project.
- Faster Turnaround: Design-build firms typically offer quicker timelines due to their integrated approach and established processes.
- Budget Control: With a fixed-price contract, design-build firms provide greater cost predictability, allowing you to track your budget more easily.
- Expertise in Both Design and Construction: Design-build firms have in-house architects and builders working together, ensuring that the project is executed as intended.
However, if you prefer to have more control over the selection of contractors or if you want to bring in specialists for specific parts of your build, working with an architect might be a better option. Architects are also ideal for projects where the design is highly specialised, and you want to work with a specific team of experts.
Conclusion: Architect vs. Design-Build Firm-Which Is Right for You?
Both architects and design-build firms play valuable roles in home construction and renovation projects, but their approaches differ. Architects focus on the design and regulatory compliance of your project, while design-build firms offer a more integrated approach that handles both design and construction.
If you’re looking for a seamless, coordinated experience with predictable costs and timelines, a design-build firm may be the ideal choice. On the other hand, if you value flexibility and want to select specialists for different aspects of the project, working with an architect could be the best path for you.
Ultimately, the decision comes down to your project’s nature, your budget, and how much control you want over the process. Whichever route you choose, ensuring you work with a trustworthy and experienced team is key to turning your vision into reality.
Frequently Asked Questions
Can An Architect Design And Build?
An architect’s main service involves designing a space. They draft the entire building, spaces, entries, exits, exterior landscaping, and even, sometimes, all the way down to the light fixtures. Some architects design the shell of a house, and contractors figure the rest out. They don’t usually build.
When Should You Use An Architect?
They will guide you through the design, planning and construction process whether you are constructing a new building or adapting an existing property. Architects apply impartial and creative thinking to projects large and small.
What Are The Two Types Of Design-Build Services?
There are two basic types of design-build services, one by the architect and the other by the contractor. The duties of the architect and contractor change depending on which of these two basic approaches is utilised.
Who Pays The Labourers In A Design-Build Service?
The Client
The client directly pays all costs for labour and materials. The architect does not advance any money to pay expenditures connected with the work. Generally, a revolving fund is given to the architect beforehand, accounted for, and is subject to periodic auditing by the client.
Who Owns The Design In Construction?
This may shock many owners, but the architect has the rights. Even though you may have paid for design work on the original building, the architect retains ownership and significant control over the design documents based on copyright law and the terms of a commonly used owner-architect agreement.
