We’re incredibly proud to have been the builders behind the winning house - House 2 on My Reno Rules! 🏆

A huge thank you to all of the trades and suppliers involved in this massive project. What we achieved in such a short timeframe is truly incredible, and we couldn’t have done it without your hard work and dedication.

Congratulations to the winners, Mitch and Shaz , and to runners-up Franky and Issac . It was an absolute pleasure working alongside you all, and we’re so glad to see your efforts recognised. You should be incredibly proud of what you accomplished.

What a journey, and what a result! 👏🔨

We love a before and after...

From an old brick house to a forever home built for a lifetime of healthy living. 🌿

When this young family first came to us, they'd already done their homework. They knew what they wanted. A home that would be kind to the planet and kinder to their little girl growing up inside it.

So we got to work. Together.

✅ Full knock-down rebuild
✅ SIPS panel construction for exceptional insulation & airtightness
✅ Heat Recovery Ventilation (HRV) for fresh, filtered air year-round
✅ Low VOC paint throughout — because what's in the air matters
✅ Recycled bricks — beautiful, sustainable, full of character

Every detail of this home was chosen with intention, for their daughter, for their future, and for the earth.

This is what building better looks like.

Thinking about a home that truly works for your family? We'd love to have a chat. 📞 Call us on 1300 560 300

We’re incredibly proud to share that Coys Constructions has been awarded 2026 Australian Achiever Awards – Highly Recommended Status in the Architect Services, Building Design, Building Construction & Interior Design Services category.

Receiving an overall score of 87.70% for customer relations and service is something we’re extremely grateful for, especially in an industry where trust, communication and consistency matter so much.

Building and renovating homes is never just about construction to us. It’s about guiding clients through a major life investment with honesty, care and transparency from start to finish.

We’re proud that our strengths highlighted in the review included:
✔️ Communication
✔️ Educating clients
✔️ Explaining technical aspects clearly

A huge thank you to our clients, trades, suppliers and team who continue to support what we do every day.

We know the building industry can be challenging at times, so recognition like this means a lot to our small business.

Here’s to continuing to build quality homes and strong relationships across Melbourne’s east.

We just ran our first blower door test on our latest new build and the results are exciting. 🏠💨

For context: this result was achieved with just the external building wrap in place. No airtightness membrane. No plasterboard. Just wrap.

📊 Result: 1.47 ACH @ 49Pa

To put that in perspective, a standard Australian home typically tests at 10–15 ACH. A Passive House standard is 0.6 ACH or less. We're already well on our way and we're only at stage one.

We'll be running two more tests as the build progresses:
✅ Test 1 — External wrap only (done! 1.47 ACH)
⬜ Test 2 — Once the airtightness layer is installed
⬜ Test 3 — Once plastered and complete

This is how we build differently. Every gap matters. Every seal counts. Because a truly healthy, energy-efficient home doesn't happen by accident, it's tested, measured and proven.

We’ve been blessed with a warm Autumn, but the colder weather is definitely on it's way ❄️

Is your home ready for winter?

Spend this weekend checking off these few simple maintenance items and thank us later!

A warm, comfortable home isn’t just about turning the heater on, it’s about how well your home performs as a whole.

A little preparation now can make a big difference over winter ☕🔥

We often get asked why renovations cost what they do.

The reality is, a lot of the work isn’t immediately visible.

Behind every extension or new build is proper planning, coordination, compliance, waterproofing and quality workmanship.

These are the things that protect your home long after the project is complete.

Because a renovation should add value, not future problems.

Most of the work happens before the build even starts.

By modelling and planning each project in detail, we can step onto site with clarity and confidence.

Because a well-planned build is a better build.

The difference is always in the details.

From material selection through to final finishes, every element plays a role in how a space looks, feels and performs over time.

It’s what turns a good result into a great one.

Thinking about renovating? It pays to get the details right from the start.

There’s really no right answer - just what suits your space, your style and how you want it to feel every day.

We love working with both.
