What Our Customers Say About Us

"DBC have been amazing with our renovation - we have been dealing with the lovely Tayla and nothing is too much trouble. So happy with all her colour and fixtures and especially the design of our new Ensuite - going to look magic. Can't wait for the final stages to be completed. Thankyou Thankyou Tayla for all your help and expertise. Thoroughly recommend DBC Interiors to anyone seeking home improvements."

"We recently had the pleasure of working with DBC Interiors on our bathroom renovation & home updates, and we couldn't be happier or recommend them more highly! Gemma and Kristy are absolutely amazing. They truly understood what we were after, & their ability to interpret how we wanted the space to feel—not just look—was exceptional. The entire process has been enjoyable. The communication and attention to detail has stood out, and the results have exceeded our expectations! Every part of our project is thoughtfully considered, beautiful, and functional!"

"Thank you to Kristy Gathercole and the wonderful DBC Team who gave my holiday home a whole new fresh Beachy vibe. I love coming down each time to share with family and friends. It has given more light and warmth to an already beautiful home and was completed all in good time for the arrival of our beautiful new grandson. One very happy client. Well done DBC, Kristy, Mariana and the team."

"I had a very informative session with Tayla who provided me with useful advice regarding colouring and finishes for my new home build. It was to be a one off session but I think I will be back for a bit more assistance in making sure that I don't make any major decisions that have not been thought through and discussed with a professional. Thanks Tayla. See you again in the new year."

"We are currently going through our second design project based on the wonderful experience we had on our coastal home. Both Tayla and Kristy are good listeners and talented. They exceeded our expectations with the concept, organisation and delivery."

"Kristy and Tayla were so helpful with making our vision a reality! (So much better than we imagined!) DBC helped turn our 1990s beige home into a beautiful family home for today family living and beyond! Thanks for all your help! Highly recommend."

"We first met Kristy & the team when deciding to sell our home of 38 plus years, retire from working & downsize! A scary time, we then added building a new home to the list. Kristy & the team's ability to listen to our thoughts & likes has created a vision for our future that we love. Thank you all so for taking away the scary & the stress & making our build an enjoyable & exciting experience. Thank you Kristy, Mariana & Gemma."

"Kristy and the team at DBC were such a joy to work with. I had some ideas of what I was after which they were very careful to listen to. They laid out a clear process upfront too so I knew what to expect. From there they brought to life my ideas and enriched them with their own expert design concepts. They were very keen to collaborate to get to the right design outcome both functionally and aesthetically. My home renovation is now complete and I could not be happier."

"We have recently worked with DBC Interiors for our new build. Kristy & her team are incredible to work with. We loved their attention to detail and aesthetic eye. They absolutely nailed our brief. I highly recommend DBC Interiors for anyone looking for an interior designer."

"We have received incredible service from DBC. They are extremely talented in their designs, very efficient and helpful."

"Kristy and her team did an amazing job for our build in Mt Eliza. The design side of things was beautiful and responsive to the brief... but just as importantly the attention to detail and commitment to seeing the job through was first class. Great communication throughout and just a great group of people to work with."

FAQ

Have questions about your renovation, extension, or new build? You’re in the right place. At Design Build Collective, we understand that whether you’re transforming an existing space, expanding your home, or building from the ground up, there are important decisions to make. To give you clarity and confidence from the very beginning, we’ve answered some of the most common questions below. From timelines and budgeting to our process, permits, and guarantees, you’ll find the guidance and peace of mind you need right here.

What does the process look like for a new build, renovation, or extension?

Every project begins with an in-depth consultation to understand your vision, goals, and budget. From there, we guide you through design development, approvals, detailed costing, and construction. Whether it’s a full new build, a home extension, or a renovation, our structured process ensures clarity at every stage — from concept through to final handover.

How long does a new build, renovation, or extension typically take?

Every project is unique. After our initial consultation, we provide a detailed timeline tailored to your specific renovation, extension, or new build. This schedule outlines each stage of the process – from planning and approvals to construction and final handover. We prioritise clear communication and proactive project management to keep everything on track, with regular progress updates along the way.

How do you price projects and what is included in your quote?

We provide transparent, fixed-price quotes once we clearly understand the scope of your renovation, extension, or new build. Our detailed estimates break down materials, labour, permits, project management, and any specialist trades involved. We believe in upfront clarity so you can make informed decisions with confidence. Your initial consultation helps us develop an accurate and fair proposal tailored to your project.

Do you handle the required permits and inspections?

Yes, absolutely. As a licensed and insured contractor, we manage all necessary permits and coordinate required inspections for renovations, extensions, and new builds. We work closely with local authorities to ensure your project meets all regulations and building codes, giving you complete peace of mind from start to finish.

How do you protect my home and belongings during construction?

Protecting your living space is a top priority. We use heavy-duty floor and furniture coverings, establish designated work zones, and implement strict daily clean-up procedures. We treat your home with the utmost respect, minimizing dust and disruption to the areas not under construction to keep your daily life as normal as possible.
