The Tombay Experience
Transforms Builder Disappointment Into Your Dream Home
You’ve seen what volume builders deliver. Cookie-cutter designs. Rushed timelines. Zero flexibility when you want to change something.
At Tombay Constructions, we build the home you actually want, not the home that’s easiest for us. Every room purpose-built. Every detail exactly as you imagined. Because after 25 years, we’ve learned that personalised service isn’t optional. It’s everything.
Build In Your Budget
Why 79% of Melbourne Homeowners Exceed Their Custom Build Budget
You’ve spent months planning. You’ve saved for years. You’ve finally decided to build the custom home you’ve always wanted, not another cookie-cutter volume build that looks identical to thirty other houses on the street.
Then you start getting quotes. One builder for custom homes quotes $1.2M. Another says $1.12M. The third? $1.05M. That lower number starts looking pretty good.
Here’s what happens six months into the build. The soil report wasn’t factored in. Add $12,000. Those specific tiles you selected? Not included in the original quote. Another $8,500. The plumbing upgrades to meet current code? That’s $7,200 more. Week after week, the variations keep coming.
79% of Australian homeowners exceed their build budget. Not by a little. By tens of thousands of dollars. According to the Australian Bureau of Statistics, average new house completion times have increased 50% since 2019, from 6 months to over 9 months, partly due to builders juggling too many projects with insufficient resources.
This isn’t bad luck. It’s how many volume builders operate. They win the job with a low quote, then make their profit on variations. By the time you realise what’s happening, you’re already committed. Breaking the contract means losing your deposit and starting from scratch.
30.6% of homeowners say hidden costs are their biggest fear when building and 60% have paused or abandoned projects entirely when unexpected costs drain their budget. And with recent waves of builder bankruptcies affecting even large companies, choosing the wrong custom home builder isn’t just expensive. It’s risky.

Expectations Building With Us
What to Expect Working with Tombay's Custom Home Builders
Building a custom home should feel exciting, not stressful. After 25 years and 70+ completed projects, we’ve refined our approach to eliminate the frustrations that plague most builds. Here’s exactly what you can expect.
Realistic Timelines You Can Trust
Most custom home builds take 12-18 months from breaking ground to handing over keys. We’ll provide a detailed timeline during your quote that accounts for council approvals, site conditions, and realistic construction schedules. No inflated promises to win the job, just honest timeframes based on actual experience building custom homes across Mornington, Rye, Sorrento, and Mount Eliza.
Fixed Priced Contracts
You’ll receive a comprehensive quote before we start that covers every aspect of your project. Our fixed priced priced contracts mean the price we quote is the price you pay. No surprise variations. No hidden costs. Complete transparency about where your money goes. This approach protects you from the budget blowouts that affect nearly 8 in 10 Australian homeowners.
Premium Craftsmanship Standards
All our carpenters work directly for Tombay. They’re not subcontractors juggling three other jobs. They show up when promised, care about their craft, and take pride in quality work. When 50% of homeowners struggle to find a tradie who even shows up on time, having reliable, skilled carpenters makes all the difference.
One Dedicated Point of Contact
You’ll work with the same person from your first conversation through to final walkthrough. No being passed around between different people. No confusion about who’s responsible for what. Poor communication causes 52% of rework and 20% of project delays in the building industry. We eliminate that by giving you one consistent contact who knows your project inside out.

Experienced Team
Meet Lee & The Team: Building Trust Through 25 Years of Custom Craftsmanship
After 25 years in the building industry, Lee started Tombay Constructions with a simple belief: homeowners deserve better than being passed around between different people, hit with surprise costs, and left wondering if their builder even cares.
Lee has seen firsthand what happens when builders cut corners or treat projects like production lines. That’s not how Tombay operates. Every client works with Lee directly from first conversation to final walkthrough. One point of contact. Clear communication. No confusion about who’s responsible for what.
All our carpenters are employed directly by Tombay. They’re not subcontractors juggling five jobs at once. They show up when promised, care about their craft, and take pride in quality work. When 50% of homeowners struggle to find a tradie who even shows up on time, having reliable, skilled carpenters makes all the difference.
For Lee and the Tombay team, these aren’t just construction projects. These are the homes where families will live for decades. Where kids will grow up. Where life’s biggest moments will happen. That’s why we use fixed priced contracts, maintain full transparency, and never compromise on quality. Because when someone trusts you with their forever home, you don’t take shortcuts.

Investment Guide To Custom Home Building
What Does a Custom Home Builder Cost in Melbourne?
Typical Custom Home Investment Ranges
Most custom home builds in Melbourne’s Bayside and Peninsula regions range from $950,000 to $1.5 million, depending on size, finishes, and complexity. Industry data for 2024-25 shows construction costs of $3,000-$3,800+ per square metre for medium to high-end finishes.
Smaller custom homes (150-200sqm) with quality finishes typically start from $650,000-$750,000. Premium custom builds (250-350sqm) with luxury finishes often range $900,000-$1.5 million+. These ranges cover construction only and exclude land purchase.
What Affects Your Investment
Design complexity drives cost variations. Multi-level homes with complex angles cost more than simple single-storey designs. Site conditions matter significantly. Sloping blocks require cut-and-fill work. Coastal locations like Sorrento or Rye need additional engineering for soil conditions.
Material selections create substantial cost differences. Stone benchtops versus laminate. High-performance glazing versus standard windows. Custom building means you choose everything, and those choices directly impact final costs.
Council requirements vary by municipality. Heritage overlays add expenses. Bushfire regulations in certain Peninsula areas require specific materials and construction methods. We factor these predictable costs into quotes upfront.

Mistakes Costing Melbourne Homeowners
Costly Mistakes When Choosing Custom Home Builders Melbourne
After 25 years building custom homes, we’ve seen these mistakes cost Melbourne homeowners tens of thousands of dollars. Here’s how to avoid them.
Mistake #1: Choosing Based Solely on the Lowest Quote
The cheapest quote often becomes the most expensive project. Volume builders win jobs with artificially low quotes, then profit from variations. By the time hidden costs surface halfway through your build, you’re committed. Breaking the contract means losing your deposit.
Mistake #2: Not Verifying Builder Credentials Thoroughly
51% of Australian homeowners report issues with their builder. Many problems could have been avoided by checking licenses, insurance, and association memberships before signing.
Mistake #3: Accepting Vague Allowances Instead of Fixed Specifications
Insist on detailed specifications for everything. Exact tile types. Specific tap brands. Particular appliances. The more detailed the quote, the less room for expensive surprises. Fixed priced contracts eliminate this problem by specifying everything upfront.
Why Choose Us For Custom Home Building
How Tombay's Custom Home Builders Melbourne Approach Delivers Your Vision
Anyone can promise a custom home. The difference is in how it’s actually delivered. Here’s what sets Tombay apart.
Design exactly the home you want, not a modified version of ours.
You’ll get exactly the home you imagined, not a slightly modified version of our standard plans. Want a specific roof pitch? Open-plan living that flows to outdoor entertaining? A kitchen that becomes the heart of family life? We’ll work with you and your architect to bring that vision to life.
We collaborate closely to translate your ideas into detailed architectural plans. Some clients choose from our pre-designed custom plans and modify them heavily. Most design from scratch. Either way, you’re the architect of your dreams. We’re just here to make it happen.
This matters because your custom home should reflect your lifestyle, not ours. Every room purpose-built. Every detail exactly as you specified. Because after 25 years building bespoke homes, we’ve learned that personalised service isn’t optional. It’s everything.
Your final build cost locked in from day one.
71% of Australian builders now offer fixed-price contracts because homeowners demanded it. We’ve been doing it for years. You’ll know the final cost before we break ground.
Our fixed cost-plus approach means you see exactly where every dollar goes. Materials. Labour. Permits. Everything itemised and transparent. No vague allowances that mysteriously run over. No surprise variations three months into the build.
This eliminates the stress that plagues most custom builds.
One dedicated contact from first conversation to final walkthrough.
Remember that stat about communication failures causing 52% of rework? That happens when you’re passed around between estimators, project managers, site supervisors, and administration staff. Nobody has the full picture. Decisions fall through cracks.
At Tombay, you get one dedicated contact who knows every detail of your custom home. They’ve been involved from your first conversation. They understand your vision. They’re accountable for delivering it.
No chasing different people for updates. No repeating yourself to five different staff members. Just clear, consistent communication with someone who genuinely cares about your project’s success.
This single point of accountability is rare in custom home building. Most builders operate like factories, shuffling clients between departments. We operate like craftsmen, treating your forever home with the personal attention it deserves.
Skilled carpenters who show up on time, every time.
When the Housing Industry Association reports that 51% of homeowners experience issues with their builder, and 50% struggle to find tradies who show up on time, having reliable skilled carpenters on staff becomes a massive advantage.
Our team has worked together for years and are employed directly by Tombay. They know our standards. They understand what custom home building requires. And because they’re not rushing to another job site, they can focus on getting your build right the first time.
At Tombay, you get one dedicated contact who knows every detail of your custom home. They’ve been involved from your first conversation. They understand your vision. They’re accountable for delivering it.

Our Vision
At Tombay Constructions, our vision is to change how people experience building a home. We believe building isn’t about being the cheapest. It’s about being the clearest, with transparent communication and creating spaces that perfectly reflect each client’s style and way of life.
Custom Home Builders
Custom home builders play a vital role in turning ideas, sketches, and inspiration into a place you’re proud to call home. Tombay Constructions believes building should feel personal, considered, and rewarding from the very first conversation.
As a boutique Melbourne builder servicing the south-east suburbs and Mornington Peninsula, we focus on delivering one-of-a-kind homes designed around the people who live in them.
We take the time to understand your priorities and lifestyle before plans are finalised, ensuring the end result reflects the way you truly live, not just what looks good on paper.
Designed Around Your Land And Lifestyle
Every block has its own shape, outlook, and challenges, and smart design takes all of that into account. We plan your home around factors like orientation, sunlight, privacy, views, and the connection to outdoor spaces. The result is living areas that feel light and welcoming, bedrooms that offer comfort and retreat, and a natural flow between inside and out.
We also work closely with designers and consultants to fine-tune layouts that look beautiful while still being highly practical. Clever storage, smooth movement between spaces, and day-to-day usability matter just as much as visual appeal. This level of considered planning helps create a home that feels easy to live in well beyond the build itself.
Guidance You Can Rely On
Building a home can feel overwhelming without the right support. That’s why we prioritise clear, consistent communication from start to finish. You’ll always know what stage your project is at, what decisions are coming up, and how your budget is tracking.
As experienced custom home builders, we help you navigate selections, finishes, and upgrades with practical advice that balances aesthetics, durability, and value. Our goal is to make the journey feel structured and manageable, so you can enjoy watching your future home take shape rather than feeling stressed by the process.
Local Experience, Lasting Quality
Working across Melbourne’s south-east and coastal areas means we understand local council requirements, neighbourhood character, and environmental factors that influence design and construction. From sloping sites to coastal conditions, we plan and build with long-term performance in mind.
Many people start their search online by looking for custom builders near me, but true value comes from choosing a builder with both local knowledge and a strong commitment to craftsmanship. We work with trusted trades who take pride in their work, ensuring the finishes you see and touch every day are completed with care and precision.
Flexible Homes For The Future
A custom home should grow with you. We design spaces that can adapt as families change, children grow older, or work-from-home needs evolve. Multi-purpose rooms, smart storage solutions, and energy-efficient features all help create a home that remains comfortable and functional for years to come.
As dedicated custom house builders, we don’t follow a volume-driven model. Each project receives focused attention, allowing us to maintain high standards and deliver homes that feel solid, refined, and thoughtfully finished. It’s this level of care that sets a custom build apart from a standard project home.
Build With Confidence
Choosing the right team is about more than qualifications — it’s about trust and shared vision. Towards the final stages of your project, you should feel confident that every detail has been carefully considered and professionally delivered. That’s the difference experienced custom home builders make.
With Tombay Constructions, you’re not just building a house. You’re creating a home tailored to your lifestyle, your block, and your future — built with care, clarity, and a genuine commitment to quality.
