Here’s What Our Clients Have To Say About Extending and Renovating With Us

"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.”

7 Reasons We Can Deliver a Superior Sustainable Renovation or Extension


1. European Standard Build Quality & Craftsmanship.

Scottish builder Arran knows European building practices intimately, which means you’ll get a renovation or extension built with meticulous attention to detail that will be the envy of your street.

2. Healthier Renovations & Extensions With Year Round Comfort

As a result of draft-free additions that are comfortable all year round, everything is completely sealed and will never sweat, meaning you’ll avoid hidden mould and damp issues. This is critical if someone in your family suffers from respiratory conditions like asthma, as it ensures a cleaner and healthier air quality.

3. Sole Focus of The Builder / Deal directly with the owner.

Unfortunately many larger builders are building dozens of homes at once, so you end up dealing with staff - not the owner. We only work on 1-2 homes at a time, so we can ensure your home is given priority attention.

4. A Methodical Approach, With No Inconvenience.

Before we even begin, your whole project is mapped out in our project management platform which includes every single detail down to the final inspection - so you can be assured the quality of workmanship in your renovation or extension will be in a league of its own.

5. We Ask the Questions No Other Builder Does.

We’ll work hand-in-hand with the architect, engineers and all the necessary consultants throughout your entire build process - and will ask the questions no other builder does to ensure you get precisely what you want from your renovation or extension.

6. An Enjoyable Stress Free Experience From Day One.

Building can be a stressful time, which is why our relationship is our first priority, including open and honest communication.

7. Transparent Pricing, Processes and Project Management.

We’ll price your project with specific, itemised precision, so you know everything has been accounted for upfront. Openness and transparency are the foundation of trust, which is why you’ll receive a thorough explanation of our process and regular and consistent updates throughout the build.

Our Five Step Approach to A Stunning Extension Or Renovation You’ll Love

1. Free Initial Design Concept Call & A ‘Back of The Envelope’ costing

We’ll help you understand what to expect, and answer any questions and concerns you have about your extension or renovation. What’s more, we’ll get an overview of your vision, finding out exactly where you’re at, what you’d love to create and providing a rough idea of the investment required to achieve that dream. Either over the phone or via zoom, it’s a complimentary call, with no obligation.

2. Face to Face Meeting, Site Inspection and Planning Session

Sit down over a cuppa with Arran onsite to explore what’s possible for your home, refine your vision, and go step by step through our construction process. Once we both have a clear idea of what’s required, we’ll refine the cost estimate, and at your own pace you can let us know if you’d like to go ahead. 

3. Concept Sketches, 3D Renders & a More Detailed Estimate Update

At this point we’ll document everything - your ideas, concept drawings and 3D renders along with preliminary agreements. This allows us to begin the necessary surveys, soil tests, engineering quotes and considerations, and gather all the information required to create your new dream home.

4. Final Design Review and Fixed Price Estimate

It’s time to recap the entire process, apply for the necessary permits and create the final documents, plan drawings and agreements to move forward. We’ll also work with external third parties (on factors like soil, engineering and architecture), and your building contract (which includes all your selections, designs and specs) will be signed off on and prepared for council submission.

5. Building Of Your Dream Home Commences

Put up your feet and relax knowing it’s time for us to go to work for you. We’ll handle every detail, from bringing our own site bathrooms, to handing over your completed home in 6-18months (depending on the complexity). We’ll supply regular updates and you can follow our custom construction process in real time via your portal to our online project management system.
