How to choose a custom home builder in Melbourne: four questions to ask beyond the portfolio

You are about to spend a long stretch of time with people you may have only just met. The project is likely to be one of the largest investments you will make.

Most advice on how to choose a custom home builder in Melbourne reads the same way. Look at the portfolio. Check the registration. Ask for references. Compare the quotes. All of it is sensible, but none of it shows you how the project will be run.

What matters most to the outcome is harder to see:

• whether the builder is financially sound
• whether the price you sign is the price you build to
• whether the workflow is disciplined and the quality is checked
• whether the people who shaped your home stay connected to it

These are worth asking about early, because a portfolio cannot show them.

Doug MacLeod, Founder and Director of Latitude 37, holds a Bachelor of Engineering with Honours and founded the business in 2006. Our view is that building a custom home well is as much a project management discipline as a craft. If you want the short answer, our page on how to choose a custom home builder gives it. This is the longer one: four questions, and what useful answers tend to include. The questions help you understand how a builder operates beyond its portfolio and marketing language. Consider the answers alongside completed homes, recent client experiences and the way quality is checked throughout construction.

What a portfolio can and cannot tell you

A portfolio shows a builder’s best finished work. References are chosen by the builder. Registration is a minimum requirement rather than a measure of how a business runs. A quote reflects the information available on the day it was prepared.

None of that makes them unhelpful. They answer a different question. They tell you what a builder can produce, not what working with that builder will be like.

And it is a long relationship. With Latitude 37, a custom home typically takes two to three years in total, depending on the complexity of the project and how quickly you move through the design stages:

• Concept design usually takes around three to four months, and can be quicker when you are ready to move.
• Interior design, documentation and approvals usually take eight to twelve months. It is shorter if no town planning approval is required, and longer if it is.
• Construction usually takes ten to eighteen months, with a typical home taking around twelve.

Over a relationship of that length, the questions below are the ones we would encourage you to ask any builder.

Is the builder financially strong, and how certain is the price?

Financial strength belongs at the top of any builder assessment. In recent years, a number of Australian building companies have gone out of business, some with homes still under construction. When you commit to a builder for a custom home, you need confidence that the business will be there to complete it and stand behind it. There is a second financial question too, and it is worth keeping separate: how certain is the price of your home?

No single measure guarantees a builder’s future, but longevity is one of the clearest signals. A builder that has traded through several market cycles, including the difficult ones, has shown it can manage its business responsibly over time. Latitude 37 has operated since 2006 with a disciplined approach to financial management, project selection and delivery capacity.

Ask any builder how long it has operated, how it managed through tight markets and how it plans its workload. Builders that take on work unevenly can fall into a feast-or-famine cycle, with stretches of heavy workload followed by too little work and pressure on cash flow. We deliberately limit the number of homes we commence each year, so our team can maintain close oversight of quality, program and client experience.

Building a custom home is a significant commitment, and it is reasonable to want confidence in the builder you choose. We are always happy to talk openly about how we manage our business and our financial position. Just ask.

Awards offer an outside view. Housing awards recognise finished homes. The HIA Professional Medium Builder award assesses the whole business, from management, financial practices and client service through to design, construction quality and innovation. Latitude 37 has twice been named HIA Australian Professional Medium Builder, in 2015 and 2021, and HIA Victorian Professional Medium Builder in 2014, 2020, 2022 and 2023. It was also a Victorian finalist in 2024 and 2025. Clients’ own experience is another outside view. Latitude 37 is rated 4.7 from 183 reviews on ProductReview.com.au (as at October 2026).

On the second question, price certainty, ask four things:

• what the price includes
• when it becomes fixed
• what can legitimately change it
• who carries the risk if construction costs rise

At Latitude 37, you sign a Fixed Price Building Contract once your documentation and specifications are complete and approved. The contract sets out the agreed scope, price and exclusions clearly. Before that point, coordination and technical questions are worked through in the office rather than left to be discovered on site. That preparation is what allows the price to be fixed with confidence. Changes after signing are variations.

Comparing quotes: when a lower price is not what it seems

For an equivalent home, specification, service and construction quality, reputable builders are buying labour and materials from broadly the same market. There is no hidden source of dramatically cheaper trades or materials. So if one proposal is materially lower than another, the useful question is why.

• Is it the same specification and fitout?
• Is the same construction detail included below ground and behind the plaster?
• Is there an equivalent level of project management and quality assurance, including independent third-party inspections?
• Are important items excluded, left as allowances or still unresolved?
• Is the margin one the builder can sustain for the whole project?

A price that looks low at proposal stage can rise once allowances are firmed up and missing items are added back, often at a point where you are too far in to change course. That is not true of every lower quote, but it is worth testing before you commit. We would rather give you a realistic figure early than the lowest one.

Who stays with your project, and who checks the work?

Ask any builder four things:

• who your main contact will be at each stage
• when you will meet the person running your site
• what happens if a key person is on leave or moves on
• how the reasoning behind a design decision reaches the people building it

At Latitude 37, your key people are consistent, and each joins at the right point:

• Your Client Experience Lead (Design) and Designer guide you through concept design and pricing.
• As you move into documentation and approvals, your Client Experience Lead (Delivery) is introduced. From then on they are your consistent key contact, through interior design, documentation, pre-site, construction and handover.
• Your Site Manager is introduced ahead of construction, or earlier if you would like, and works closely with your Client Experience Lead (Delivery).
• Our Construction Manager oversees delivery, with regular project reviews and site oversight, to maintain quality, program and accountability throughout construction.

Your Client Experience Lead (Design), Designer and Interior Designer also rejoin key milestone meetings. The intention is one connected team, not a series of handovers.

Our in-house model is a large part of why this works. Our Designers, Interior Designers, Client Experience and Construction teams work within one business. Design intent, your decisions and construction questions are discussed directly by the people who know your project. That continuity holds even if an individual team member changes. Where design and interior design are engaged separately, how involved those consultants stay during construction depends on how their engagement is scoped.

Quality is checked continuously through the build rather than waiting for a stage to finish:

• Your Site Manager carries out ongoing quality checks.
• Senior members of our Construction team peer review those checks at set gateways and hold points, including the mandatory inspection stages and our own internal quality gateways.
• Pre-plaster is a key hold point, where work is checked before it is concealed.
• Independent third-party specialists also inspect at defined stages, adding another level of verification alongside our internal checks.
• Defects are photo-logged and need two sign-offs before they are closed.

Whichever builder you are considering, ask how its checks are carried out, who reviews them, and how outstanding items are closed before work moves on.

How openly does the builder talk about budget before you commit?

Every builder will form a view on whether your site and budget can support your brief. How that conversation goes is one of the most useful indicators you will get. It shows how the builder behaves when the honest answer may not be the one you hoped for.

At Latitude 37, the first meetings explore fit: your brief against your budget, and the constraints and opportunities of your site. If the honest answer is that they do not fit, we would rather say so early than after months of design work.

Your budget is then considered throughout the design and documentation process. A Concept Design Agreement begins Concept Design, starting with your budget and design brief. We design your home to suit your brief, site and budget. Once you are happy with the design, we prepare a Custom Home Proposal before you commit to the documentation phase. It is a detailed, scope-based estimate of the proposed inclusions, key allowances and assumptions. As documentation progresses, allowances are progressively replaced with firm pricing. We have explained how the cost becomes known at each stage, and what actually drives the cost of a custom home, separately.

Early information can change a design for the better. At Waterfront in Patterson Lakes, the family’s original thinking included a basement. Working through the site early showed that building below ground would add complexity and cost without adding to the way the family wanted to live. Instead, the home was organised across three levels above ground. It accommodated everything the brief asked for, at a lower cost overall. Waterfront is a finalist in the 2026 HIA Victorian Housing and Kitchen & Bathroom Awards, in the Custom Built Home Over $6 Million category. The story of how the whole family shaped its brief is told in our Knowledge Hub.

So ask directly what your budget will not support. “It depends” can be an honest answer. The useful follow-up is what it depends on, and how the builder will tell you when it knows.

What happens after you move in?

Handover is not the end of the relationship. Ask any builder:

• what you receive at handover
• how you report an issue
• who is responsible for it
• how you will be kept informed
• how urgent problems are handled in the first year

At Latitude 37, you receive a Maintenance & Warranty Guide for your home at handover. For the first 90 days, the Site Manager who delivered and handed over your home manages your maintenance process, including your 90-day maintenance inspection. After that, our Maintenance & Warranty partner manages warranty matters on Latitude 37’s behalf. Whenever you need us, before or after 90 days, you raise maintenance and warranty requests through our online Aftercare Request form. You also have 12 months of complimentary RACV Home Assist for urgent call-outs. None of this limits your statutory warranty rights. The rest of what happens after handover is on our aftercare page.

Four questions, then:

1. Is the builder financially strong, and how certain is the price?
2. Who stays connected to your project, and who checks the work?
3. How openly does the builder talk about budget before you commit?
4. What happens after you move in?

They apply to Latitude 37 as readily as to anyone else. Many of the people we build for are clients who arrive through referral, sent by someone who has been through the whole process with us. First-time builders are welcome too. Many of our clients are building for the first time, which is often why they want one end-to-end design-and-build team.
