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.

Avoid The Heartache

Why Volume Builders Turn Knockdown Rebuilds Into Budget Nightmares

Your family needs more space. The kids are sharing bedrooms. There’s no home office. The kitchen layout hasn’t made sense since 1987. You love your street, your neighbours, the school zone. Moving means stamp duty, real estate fees, and starting over. So you research knockdown rebuild options. The volume builder quotes $920,000 for a four-bedroom home. Their display homes look great. You sign the contract. Then the real costs start appearing: – “Unexpected” soil issues require upgraded footings: $18,000 – Electrical connection relocation: $6,500 – Asbestos removal from existing home: $12,000 – Additional council drainage requirements: $8,200 According to the Housing Industry Association, knockdown rebuilds now represent nearly one third of all new detached homes in Australia. Yet most builders quote these projects like standard new builds, ignoring the complexities of demolishing existing structures. Volume builders operate on slim margins. They win jobs with low quotes, then recover profit through variations. By the time you discover the real cost, you’re committed. Stopping means losing your deposit. Continuing means draining savings you didn’t plan to touch. Here’s how knockdown rebuild specialists operate differently: They conduct thorough site assessments before quoting. They account for demolition complexities, service relocations, and council requirements upfront. They use fixed cost-plus contracts so you know the final price before demolition begins. No surprise variations three months into your project project.

Expectations Building With Us

What to Expect from Tombay's Knockdown Rebuild Service

Most knockdown rebuild guides focus on construction timelines. But here’s what really matters: managing your life while your home gets demolished and rebuilt.

Finding Temporary Accommodation That Works

You’ll need somewhere to live for 12-18 months. We help you plan this transition before demolition starts, not after. Most clients rent nearby to maintain school runs and routines. Budget $2,500+ monthly, plus storage for furniture you’re keeping. We coordinate demolition timing so you’re not paying double housing costs longer than necessary.

Watching Your New Home Take Shape

Unlike buying existing homes where you see the finished product, knockdown rebuild means watching your house emerge from bare ground. We schedule site walks every fortnight so you see progress firsthand. Frame going up. Roof structure taking shape. Rooms becoming recognisable spaces. This involvement means you understand how your home was built, not just what it looks like completed.

Handling the Paperwork and Approvals

Demolition permits. Building permits. Service disconnections. These administrative tasks multiply when you’re replacing an existing dwelling. We manage every council interaction, every service provider coordination, every inspection booking. You’ll know what’s happening and when, but you won’t be chasing paperwork while living in temporary accommodation.

The Reality of Timelines

Demolition permits take 4-6 weeks. Demolition itself takes 1-2 weeks. Council planning approvals can take up to 12 months. Construction takes 8-12 months. Total project: 12-18 months from signing contracts to moving in. These aren’t best-case scenarios. They’re realistic timeframes that account for Peninsula council processes and Melbourne weather delays.

Experienced Team

Building Melbourne Knockdown Rebuilds Since 1999: Experience That Protects Your Investment

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 custom home builder even cares about delivering their vision.

Lee had seen firsthand what happens when builders cut corners or treat custom projects like production lines. Cookie-cutter designs. Rushed timelines. Zero flexibility when you want to change something. That’s not how Tombay operates.

Every Tombay client works with Lee directly. One point of contact. Clear communication about design choices, material selections, and any decisions that need to be made. No confusion about who’s managing your custom build.

We’ve built custom homes throughout Mornington, Rye, Sorrento, and Mount Eliza. We understand local council requirements. We know which suppliers deliver quality materials on time. We’ve established relationships with local trades who share our standards.

This local knowledge means we can navigate the specific challenges of building in Peninsula municipalities. Coastal soil conditions. Heritage overlays. Bushfire regulations. Site access on narrow streets. These aren’t theoretical concerns. We’ve solved them dozens of times.

Investment Guide To Knockdown Rebuilds

Knockdown Rebuild Cost Guide for Melbourne Homeowners

Most Melbourne knockdown rebuilds cost between $700,000 and $1.1 million+ according to current market data. Here’s the breakdown so you can budget realistically.

Demolition costs separately: $12,000-$40,000 depending on home size, asbestos presence, and site access. Asbestos removal adds $50-$100 per square metre.

Temporary accommodation: Budget $2,500 monthly for 12-18 months. That’s $30,000-$45,000 many homeowners forget to include.

The Hidden Costs Volume Builders Don’t Mention

Service relocations: Electrical, gas, water connections often need moving. $8,000-$15,000.

Soil upgrades: Poor soil conditions require engineered footings. $15,000-$30,000 if discovered after quoting.

Council contributions: Some Peninsula councils charge development levies. $5,000-$12,000 depending on location.

Landscaping restoration: Your existing gardens get demolished. Budget $10,000-$25,000 to restore.

Why Our Quotes Include These Costs Upfront

When I inspect your existing home, I’m checking soil reports, identifying asbestos, mapping service locations, and reviewing council requirements. These costs get included in your quote, not discovered mid-project.

You’ll know your total investment before signing anything. No demolition crew showing up to find asbestos and hitting you with $20,000 in unexpected removal costs.

Mistakes Costing Knockdown Rebuilders

Top 3 Expensive Knockdown Rebuild Mistakes Melbourne Homeowners Make

After 25 years managing knockdown rebuilds, I’ve seen these mistakes cost thousands. Here’s how to avoid them.

Mistake #1: Underestimating Total Project Costs

Most homeowners budget only for construction, forgetting demolition costs ($12,000-$40,000), asbestos removal ($7,500-$15,000 for pre-1990 homes), temporary accommodation ($18,000-$45,000 over 12-18 months), and landscaping restoration ($15,000-$30,000).

That $520,000 building quote becomes $600,000+ when you include mandatory extras. Budget for the complete project from day one, not just construction.

Mistake #2: Choosing Builders Without Knockdown Experience

Knockdown rebuilds require coordinating demolition, managing asbestos, relocating services, and navigating council approvals for replacement dwellings.

Ask how many knockdown rebuilds they’ve completed. Request references from knockdown clients specifically, not just new builds.

Mistake #3: Signing Contracts Before Demolition

Some builders want contracts signed before demolition. They haven’t seen actual site conditions yet. Soil quality, underground services, and contamination issues only become visible after demolition, leading to “unforeseen” variations you’re locked into.

Work with builders who complete demolition and full site assessment before finalising building contracts.
