Every new home gets leak tested

“I’ve seen first-hand many of the health and structural issues with building to the minimum Australian industry standards.  

Many homes ‘leak’, which leads to poor air quality, mould and fungal growth literally eating away at the timber framing. 

That’s why I became a Passive House Tradesperson and Green Living Master Builder, and started Conscious Construction Co, in order to build environmentally friendly homes that deliver cleaner, fresher & filtered indoor air, and are the standard by which others are judged.”

Most Australian homes suffer from Leaky Building Syndrome. While most homes look great initially, over the years moisture accumulates either via water vapour permeating from the interior of the building, or dew condensing from ambient air entering the cavity.  


By the time you realise it’s a problem, it’s usually too late. 

When you build with us, we install premium permeable wall and roof membranes (sarking) for airtightness, creating a ventilated cavity that stops the fungal growth.

What’s more, we leverage correct ‘wrapping’ practices to keep your house dry and protected, without sweating (which can lead to damp and mould issues). We tightly seal and wrap external walls to prevent even the slightest of draughts getting in or out (eliminating cold feet, and keeping the rest of you warm, regardless of the temperature outside).


• We use wider timbers for our stud walls (140mm where possible, based on British minimum standards): not only for more structural integrity, but to create more depth for thicker insulation to sit in - keeping you and your family in year round comfort, regardless of the temperature outside.
• Provide higher grade insulation: not just in the external walls, but also the internal walls to regulate temperature and reduce sound penetration with greater efficiency.
• Seal doors and air gaps around the home: which also make it one of the quietest homes you’ve ever encountered, cutting down noise from both inside and out.
• Use ‘smart ventilation’ to repel mould and extract dust: ensuring your home is free from irritants that could cause illness, and offering relief for allergy sufferers.
• Eliminate CO2 buildup: giving you clearer focus and greater productivity, and helping you avoid the ‘3pm slump.’
• Build durable homes that require less repairs.

A Passive House which uses 90% less energy than a standard home

Originally developed in Germany in the 1990’s, Passive House is a design standard that achieves thermal comfort with minimal heating and cooling by using insulation, airtightness, ventilation systems, specific door and window design, the elimination of thermal bridges and heat recovery in order to minimise air leakage, reduce air pollution, and slash your electricity bill and carbon footprint.

Here’s What Our Clients Have To Say About Building Their Stunning New Custom Dream Home With Us

“We've used Arran and his team on several occasions in various capacities, and always found them friendly, courteous and client focused. Arran works hard to accommodate our circumstances and is very good at seeing solutions rather than problems. We intend to continue to use and recommend Conscious Construction Co. as much as we can.”

- Peter Conlon -

"The most important considerations for me when spending a significant amount of money on my home were, that you want a builder you can trust, and one you feel comfortable working with, and Arran ticked both of those boxes. He went above and beyond to work with me to achieve the exact finished product I had in mind."

- Heather Irving -

"Arran's attention to detail is first-rate, with the entire build wrapped and sealed tight to prevent any loss of heat, the egress of water, or the build-up of condensation. The double-glazed windows Arran recommended are also high-quality and promise to deliver years of service ahead. Many other builders keen to build seven-star houses could learn so much by studying how this build has progressed."
