Is it cheaper to renovate or rebuild?

It depends on how much of the existing home is worth keeping. As a rule of thumb, when renovation costs approach 60–70% of an equivalent new build, the rebuild option deserves serious comparison.

Can I knock down a home in a heritage conservation area?

Often not — demolition of contributing heritage fabric is usually resisted by council. In those areas the proven path is restoring the front and rebuilding the rear as a modern addition.

Does MBC do both renovations and new builds?

Yes — custom new homes (like our Rembrandt Drive build in Merewether Heights), whole-home renovations, and heritage work (like our HIA Awards finalist project in Cooks Hill). That's why we can give you an unbiased comparison.

What kind of projects do you take on?

Custom homes, whole-home renovations, extensions, bathrooms and kitchens, outdoor living, and commercial fit-outs — across Newcastle and Lake Macquarie. From a century-old Cooks Hill cottage under heritage restrictions to a ground-up new build, the common thread is high-end finishes and craftsmanship.

Where do we start if we're thinking about a project?

With a conversation. Bring whatever you have — plans, a concept, a Pinterest board or just an idea — and we'll talk through what's feasible and what it roughly involves. Michael values working closely with clients to deliver a personal, customised experience, and understands every build is unique in both design and budget.

Do we need an architect first?

No. MBC work closely with award-winning architects and building designers — including practices who name them as a preferred builder — and can point you to the right design team for your project if you don't have one yet.

Who will actually be on site?

The MBC team — Michael remains hands-on through the build, David supervises with 38 years of carpentry behind him, and the crew is a carefully selected team of qualified tradesmen. You deal with the people who do the work.

Can you work on older and heritage homes?

Yes — it's some of our proudest work. The Cooks Hill cottage renovation (an HIA Housing Awards finalist) restored the heritage front of a century-old home to its former glory, and the Bolton Street commercial project faithfully restored a 140-year-old ornate timber ceiling.

Are you licensed and insured?

Yes — NSW builders licence 267322C, held by a locally owned company based in Redhead. Licence and insurance details are provided with every proposal.

Knock down and rebuild, or renovate? How to decide

It's the fork in the road every owner of an older home eventually reaches. We build both ways — so here's the honest framework we walk clients through, without a thumb on the scale.

Start with what the house is worth keeping

Some homes have bones and character worth building around — period detail, solid hardwood structure, a streetscape you love. Others are simply tired buildings on good land. Be honest about which one you own, because sentiment is real but it isn't structural.

A builder's walk-through early answers a lot: what's genuinely sound, what's failing, and what the house would let you do. We've seen 'knock it down' houses with beautiful bones, and 'quick reno' houses hiding problems worth six figures.

When renovation wins

Renovation tends to win when the structure is sound, the location and orientation already work, and what you want is more space and modern function rather than a different house. In heritage conservation areas it often wins by default — demolition may simply not be approvable, and the character you'd lose is the reason the street is worth living on.

Our HIA-finalist Cooks Hill project is the case study: a century-old cottage in poor condition that became something special precisely because the heritage front was restored rather than erased.

When knockdown-rebuild wins

Rebuild tends to win when the existing home fights you on every front — failing structure, hopeless layout, wrong orientation — and the block itself is the asset. Starting fresh buys design freedom, modern performance and a warranty on everything, and at a certain point the renovation sums simply stop stacking up against it.

A rough rule of thumb we use: when renovation costs push past 60–70% of the cost of building new for the outcome you actually want, the rebuild conversation deserves to be on the table.

Run both numbers honestly before you decide

The mistake is deciding first and pricing second. Map both paths — realistic renovation scope versus rebuild — with honest numbers, approval pathways and timelines side by side. Sometimes the answer is obvious. Sometimes it genuinely could go either way, and then it's about what you value: character and continuity, or a clean sheet.

Because we build custom homes, whole-home renovations and heritage work, we don't need to steer you either way. Bring us the house and the vision, and we'll help you run the fork in the road properly.
