When researching builders, one of the first things many homeowners look at is experience.
And for good reason.
Building is a complex industry where knowledge is accumulated over years - and often decades - of solving problems, refining systems, managing trades, navigating approvals, and delivering projects for clients. There are lessons that simply can't be learned from textbooks or websites.
A builder who has successfully delivered projects over many years has likely experienced changing regulations, fluctuating market conditions, supply chain disruptions, difficult site conditions, and countless unexpected challenges. That experience can provide confidence that they have the systems and expertise to navigate issues when they arise.
To explore what homeowners should look for, we spoke with Ross Thomson, Managing Director at Cape Cod Australia, a company that has specialised in home additions and renovations for more than 60 years.
Experience comes in different forms
While years in business are important, it's also worth understanding where that experience has been gained.
A builder may have decades of experience, but that experience can be concentrated in a particular type of work.
For example, building new homes, renovating heritage terraces, constructing duplexes, and adding second storeys all involve different skills, approvals, engineering requirements, and construction challenges.
This doesn't diminish the value of overall experience. In fact, a long track record often reflects a builder's ability to consistently deliver projects and adapt over time. However, homeowners can gain additional confidence when that experience closely aligns with the type of project they're planning.
Ross says one of the biggest lessons they've learned over decades in business is that successful projects begin long before construction starts:
"Over more than six decades, we've learned that successful projects aren't just about construction - they're about planning, communication and anticipating challenges before they arise.
Every home, family and site is different, but the experience gained from delivering thousands of projects allows us to identify potential complexities early and give homeowners a clearer understanding of what their project is likely to involve. We've found that investing time upfront to properly scope a project and explain what is and isn't included helps minimise surprises and gives homeowners greater confidence throughout the building journey."
For homeowners, this means it's worth asking two questions:
- How long has the builder been doing this?
- How much experience do they have with projects like mine?
The strongest candidates are often those who can answer both.
Look for relevant experience
If you're planning a second-storey addition, a builder who completes dozens of similar projects each year may be a better fit than a builder who primarily constructs new homes.
Likewise:
- A heritage renovation benefits from heritage experience
- A sloping block home benefits from experience with complex sites
- A duplex project benefits from experience with dual occupancies and subdivision requirements
Specialisation doesn't automatically make a builder better - but it often means they've encountered similar challenges before and developed systems to manage them efficiently.
Ross says this is particularly important with second-storey additions:
"A second-storey addition is fundamentally different from building a new home or undertaking a knock down rebuild. You're working with an existing structure, existing services, council requirements, and often a family continuing to live in the home during construction. These projects require careful planning and a thorough understanding of how the new and existing parts of the home will work together.
Experience in this area allows us to identify many of the factors that can influence cost and construction outcomes before work begins, helping homeowners better understand the scope of their project and make more informed comparisons when assessing builders and quotations."
The value of seeing patterns
Builders who have completed hundreds of similar projects often identify issues early because they've seen them before.
That might include:
- Design challenges
- Approval hurdles
- Structural constraints
- Construction sequencing issues
Ross believes one of the greatest benefits of experience is pattern recognition:
"After completing thousands of home additions and second-storey projects, we've developed a deep understanding of the costs, challenges and decisions that commonly arise throughout the building process. While no builder can foresee every eventuality, experience allows us to identify many of the items that can impact a project's budget and address them early.
We've learned that homeowners are best served when they have a clear understanding of what is included in their proposal, what assumptions have been made, and what potential variables may still exist. Asking these questions upfront can help avoid unexpected costs later and allows clients to compare builders on a true like-for-like basis."
Experience helps before construction starts
Many homeowners associate experience with what happens on site.
But some of the biggest benefits occur long before construction begins.
Experienced builders often provide valuable input during:
- Feasibility assessments
- Design development
- Budgeting
- Planning approvals
- Engineering coordination
Ross believes early planning is one of the most valuable ways experience can help homeowners:
"The most cost-effective problem to solve is the one identified before construction begins. Thorough planning, detailed design development and comprehensive budgeting help establish a clear pathway for the project and significantly reduce the likelihood of surprises during construction. We encourage homeowners to ask their builder detailed questions about what is included in the contract price, what may be excluded, and what allowances have been made for items that cannot yet be fully defined.
The more clarity that exists at the beginning of a project, the more confidence homeowners can have in the budget and the smoother the construction process is likely to be."
Ask about recent projects
One useful question homeowners can ask is:
"Can you show me projects you've completed recently that are similar to mine?"
Recent examples often provide a clearer picture than a company timeline. Look for:
- Projects of similar size
- Similar complexity
- Similar site conditions
- Similar budget range
Ross says homeowners should look beyond finished photographs and understand how previous projects actually unfolded:
"When speaking with a builder about previous projects, homeowners should ask about the journey. Were there any unforeseen challenges? How were they managed? How closely did the final cost align with the original proposal?
These conversations can provide valuable insight into a builder's experience, planning processes and transparency. A builder who takes the time to explain what is included, what may not be included, and where potential cost risks exist is helping clients make more informed decisions and better prepare for the realities of construction."
How Build Index can help
When comparing builders, experience can sometimes be difficult to assess.
Build Index helps by providing visibility into factors such as:
- Years trading
- Project history
- Licence information
- Awards and recognition
- areas of specialisation
Final thoughts
Experience remains one of the strongest indicators of a builder's ability to deliver a successful project.
But it's not simply a matter of counting years.
The most valuable experience is often experience that closely matches the type of home you're building, renovating, or extending.
By looking beyond the headline number and understanding what a builder has actually spent those years doing, you'll be in a much better position to find a builder who is the right fit for your project.
