Our Projects


Here is a snippet of some of our latest projects.

Guiding You Through the Building Process


We know that a building project can be an overwhelming and stressful experience, and that is why we aim to make it as simple and easy as possible for you.  We take the time to truly understand how you and your family want to live in your home. We work with you to shape and customise your building project to truly fit your lifestyle and needs. We guide you through the entire process, from beginning to end, communicating with you throughout, and making sure your build is completed in a professional and timely manner.

Step 1

initial meeting

During our initial meeting, we’ll ensure your needs and desires are understood, because each project we undertake is unique and we treat it as such. We’ll review any existing plans, discuss new ideas and go over your build options to be inline with budget, while also answering any questions you might have.

Step 2

Design & Planning

This is where we finalise all of the details for your build - We get your project designed, engineered, complete soil testing (if required) and council applications, finalise the costings and draw up a building contract. We’ll guide you throughout the process and make sure all of the i’s are dotted and t’s are crossed.


Step 3


This stage of your journey marks the beginning of the construction process, where we bring your ideas to life. Rob Debenham, the Director of Responsive Building, is the onsite builder for every one of our projects, and he will be onsite monitoring your project down to the smallest detail. Being the hands on builder onsite and supervising every aspect is how we create stunning results.


Step 4


Upon completion of the construction phase, we will officially hand over your build, ready for you to enjoy your new home, your new deck or that long-awaited wine cellar. Rob will also be on hand to answer any questions, and provide any support you may need post-completion.

What Our Clients Have to Say


“We are so grateful to Rob and the team at Responsive Building for the amazing job on our renovation. Their traders were outstanding, and attention to detail second to none. We had three kids under the ages of three and were living upstairs whilst the renovation was completed, so to say that the relationship with the builder was important on this job is an understatement - and Responsive Building truly delivered (Rob feels like another member of the family!). We made a bunch of changes along the way (often the case with a reno), and somehow Rob managed to incorporate them with minimal fuss to get the job done right. The results of the build speak for themselves and not a day goes by that we aren’t appreciated some aspect of the build. It truly enhanced our lives. Responsive Building were worth every cent.”
