Choosing a builder for one house is a fairly contained decision. Choosing a builder for a 20, 30 or 50-lot townhouse development is a different exercise altogether, and it deserves a different level of scrutiny. The stakes are higher, the timeline is longer, and a mismatch between developer and builder tends to surface at the worst possible moment: partway through construction, when changing course is expensive and slow.
If you’re an experienced developer preparing to shortlist builders for a large-scale project, here’s what’s worth checking before you sign anything.
Look for Track Record at Your Scale, Not Just Any Scale
Plenty of builders can point to a well-finished single dwelling or a small block of four units. Far fewer have proven they can run 20, 30 or more townhouses through design, approvals, civil works and construction without losing control of the programme. Ask specifically about projects at the scale you’re planning, not just the builder’s largest project on record. A builder who has delivered five townhouses well may still struggle with the coordination complexity of fifty.
Understand Who Actually Does the Work
A large development moves through many trades at once: earthworks, slab, frame, services, cladding and fit-out, often across several stages simultaneously. Ask how much of that work sits with the builder’s own team versus subcontracted trades, and how the builder manages consistency across a large number of contractors. Neither in-house nor subcontracted delivery is automatically better, but you want a clear, confident answer rather than a vague one.
Ask How They Manage Concurrent Stages
On a large site, different blocks are often at different stages of construction at the same time — one nearing completion while another is at frame stage and a third is still in earthworks. This is where inexperienced builders lose momentum, because resourcing one stage properly while three others are underway takes genuine planning capacity. Ask how the builder resources concurrent stages, and ask for a specific example of how they’ve done it before.
Check Financial Stability and Insurance, Not Just Licensing
A current QBCC licence is the minimum, not the finish line. For a project of real scale, ask about the builder’s financial capacity to carry a large development through to completion, their insurance coverage, and whether they’ve completed projects of a similar contract value without disputes or delays reaching the point of legal action. This is a reasonable question for any experienced developer to ask, and a builder confident in their own position will answer it directly.
Test Their Reporting and Communication Style Early
Before you’re locked into a contract, you can already tell a lot about how a builder will communicate once construction is underway. Do they provide clear, regular progress reporting? Do they proactively flag risks, or do you have to chase updates? For a development running over many months with your capital committed, this is not a minor consideration — it’s often the difference between a project that stays on budget and one that quietly drifts.
Ask About Their Approach to Value Management
Experienced developers know that the builder’s role goes well beyond construction. A builder who understands value management — finding cost efficiencies in design, materials and sequencing without compromising the outcome — protects your margin at every stage, not just at contract signing. Ask for concrete examples of where a builder has identified savings or efficiencies on a past project of comparable scale.
A Few Direct Questions Worth Asking
- What is the largest concurrent-stage development you’ve delivered, and what did that look like day to day?
- How much of the trade workforce is in-house versus subcontracted?
- Can you provide references from developers, not just homeowners?
- What was your process when a past project hit a delay or unexpected site condition?
- How do you structure progress reporting across a multi-stage build?
The answers to these questions tell you more about how a builder will actually perform than a glossy portfolio ever will.
Why This Matters More at Scale
A mismatch between developer and builder on a single dwelling is inconvenient. The same mismatch on a 30-lot development can mean stalled stages, blown budgets and disputes that follow the project for months. Vetting properly before appointment is the cheapest insurance a developer can buy.
Weigh the Whole Picture, Not a Single Standout Answer
It’s easy to be won over by one strong answer in a pitch meeting — a confident capacity claim, an impressive past project photo. But these questions are only useful when they’re weighed together. A builder who answers the track-record question well but is vague on financial capacity, or who talks convincingly about value management but can’t describe a real example of concurrent-stage resourcing, is showing you a gap worth taking seriously. The strongest builders for large-scale work answer every question specifically, with real examples, rather than in general terms designed to reassure rather than inform.
Put It in Writing Before You Commit
Once you’ve asked these questions and received satisfactory answers, it’s worth having the key commitments reflected in the contract or a formal pre-contract document, rather than relying on verbal assurances from the pitch process. Reporting frequency, resourcing plans for concurrent stages, and reference checks are all things a developer can reasonably ask to see documented before signing. This isn’t a sign of distrust — it’s standard due diligence for a project of real scale and value.
At Groove Properties, we work with developers delivering large-scale, multiple-stage townhouse projects across Brisbane and South East Queensland, and we’re used to being asked exactly these kinds of questions. Our project management approach is built around the coordination, reporting and value management that large developments demand, and our residential project portfolio reflects developments delivered across multiple concurrent stages.
If you’re preparing to shortlist a builder for your next large-scale townhouse development, we’d welcome the chance to answer these questions directly.
