We build architecturally designed, high-performance homes with a focus on sustainability, energy efficiency and long-term comfort.

Looking for a sustainable home builder in Geelong?

As a sustainable home builder Geelong homeowners trust, we specialise in energy-efficient, architecturally designed homes built to high-performance standards. While these homes are not formally certified to the Passive House (Passivhaus) standard, we apply many of the same construction principles, including airtight detailing, high levels of insulation and mechanical ventilation. The result is a home that uses less energy, feels more comfortable throughout the year, and is built with long-term performance in mind.

What is a high-performance home?

A high-performance home is designed to reduce energy use and maintain stable indoor temperatures through a combination of building science and careful construction. These homes typically include continuous insulation, minimal thermal bridging, high levels of airtightness, and mechanical ventilation systems to maintain fresh air and comfort throughout the year.

While not formally certified to the Passive House (Passivhaus) standard, high-performance homes follow many of the same technical principles to deliver better energy efficiency, indoor air quality and year-round comfort than standard construction allows.

Why build a high-performance sustainable home?

High-performance homes maintain a stable indoor climate, staying warm in winter and cool in summer with minimal mechanical heating or cooling. Fresh air is continuously supplied, and internal conditions remain consistent throughout the day. These homes are quieter, healthier and more efficient, supporting a better standard of living over time.

Here’s What Our Clients Have To Say About Working With The Leading Custom Home Builder Geelong:

"We had worked with our architects from Envirotecture over many years and through Covid to develop our final plan for a Passivhaus principled renovation to our federation home in Ballarat. I think we were lucky to choose a builder who is passionate about this design ethos and was able to see it through to a reality. Arran and the Conscious Construction team have delivered us a modern light filled, quiet and comfortable living space, even in our long cold winters and hot summers. The standard of workmanship is high as Arran is quite meticulous, and some of the materials required extremely small tolerances to look flat and square which have been beautifully met, so that ceiling and wall panels and shadow joins look perfect. Arran and his team were always lovely to deal with. We have been in the space now for 12 months and are continuing to enjoy the benefits of choosing both a great architecture team and builder for our forever home."

- Nick and Gaye Kimpton -

"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."

- Dr Geoff Russell -

"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 -

“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.”
