Mulholland Design & Construction

Tootgarook, VIC — Stage 2. We've opened the roof today to get the steel in. Everything's exposed for a short window, so timing and sequencing matter. Clear winter skies today — perfect timing.



Mulholland Design & Construction

A day's work.

Every offcut tells a story. Every piece cut with precision, fitted with care. This is what building a Passivhaus looks like—not just the finished home, but the hours, the attention, the craft that goes into every detail.

When you build for yourself, you don't cut corners. You cut timber to fit perfectly. You work the hours it takes to get it right. Because the home you're building is the one you'll live in. The one your family will grow in.

That's Mulholland Construction.

🎉 WE DID IT! Blower Door Test Success ✅

0.33 air changes per hour at 50 pascals—we absolutely CRUSHED the Passivhaus certification standard!

A step closer to achieving certification 🎯

Today's blower door test proved what we've been building toward: homes so airtight, so perfectly sealed, that every breath you take is filtered, every degree of comfort is locked in, and your energy bills stay beautifully low. 🍃

Conditions were right today to carry out the Certified Blower Door Test. See the data—0.32–0.34 ACH across both depressurization and pressurization. That's not just a number. That's science. That's performance. That's your forever home, certified and guaranteed.

No marketing fluff. Just measured, proven excellence.

This is what we build 🏡

Big thanks to Passive Tech for making today happen!
