Custom Design that fits your life.
At Katnich Building & Design, we design and build custom homes across Adelaide that are tailored to how you live. We don’t believe in one-size-fits-all — every home we create is shaped by your lifestyle, your vision, and the details that matter most to you.
From our first conversation to the final handover, we take a personal, collaborative approach. Whether you’re creating your forever home, planning for a growing family, or starting a development project, we’ll guide you through a process that’s clear and transparent — giving you confidence and peace of mind from start to finish.
The result? A home that’s refined, thoughtfully designed, and unmistakably yours.

Subdivision & Development Experts.
Whether you’re subdividing to build your dream home or managing a larger development project, Katnich Building & Design offers the expertise to guide you every step of the way. We support you from initial planning and council approvals through to construction and final handover or sale.
With a deep understanding of the complexities involved in residential developments, we manage each stage with care, precision, and efficiency—so your project stays on track and stress-free.
The KBD Difference.
With over 20 years of experience, Katnich Building & Design creates high-quality custom homes with a level of care and attention that sets us apart. By taking on a limited number of projects each year, we ensure every build receives the focus it deserves.
What makes our process truly seamless is our in-house design team, who work with you from the very beginning to create a home that feels effortless, functional, and uniquely yours. From layout and flow to finishes and light, we help you make confident decisions that bring your vision to life — without the overwhelm.
Our reputation has been built on trust, craftsmanship, and a hands-on approach that clients value. When you build with us, you’re choosing a personalised experience that makes the process feel simple.
Construct Only.
While we specialise in fully tailored design-and-build experiences, we also understand that some people already have plans completed by an architect or draftsperson. If you’ve already taken that step, we’re more than happy to collaborate.
We can bring your vision to life by managing the construction phase with the same care, craftsmanship, and attention to detail that defines every KBD home. Whether we’re building from our own designs or yours, we’re committed to delivering a custom home that reflects your goals, fits your lifestyle, and meets the highest standards of quality.
client testimonials
We are so happy we chose Katnich Building and Design to build our dream home. They are very professional with a great eye for detail. This was our first build and they made the whole process so easy. A really lovely team. We wouldn’t hesitate to recommend Katnich, we absolutely love our new home.
Mark, Sherralee, Regan, Samantha and the entire team were fantastic to work with. This was the first house my wife and I have built, and it was a fully custom build.Working closely with a small team and having the ability to phone Mark (the owner of the business) to check-in on the regular was brilliant.
They are very practical, to the point, and ultimately – they clearly build great houses.
We’re super happy with the end result. The price was really fair upfront (we got a few quotes), and even better once the dust had settled – as there were only a few variations throughout, nothing too major.
They were also very flexible. Allowing us to make several changes on the fly with minimal fuss.
We are very happy and can 100% recommend them
Just wanted to say thanks to Mark and the team. You worked really hard to ensure we were happy with the result, well past the handover/warranty date – much appreciated. We love the new house, it’s exactly what we were after.
Mark and the entire Katnich team were an absolute joy to work with. I’ve built several new homes and developed many properties and they were by far the best outfit! They understood the project vision, budget constraints and timeframes. Most of all they were always available with creative solutions to any issues. I highly recommend Katnich building & design.
I can’t recommend Katnich highly enough. Our experience building with Mark and his crew was seamless. Together we have built a new home to accommodate all our needs. Mum and dad downstairs and our place upstairs. It was an unusual build basically two homes in one. Mark understood what we all needed and together we incorporated everything required including an elevator for our elderly parents.
During the building process we had access directly to Mark which took away any stress. Mark always responded quickly with any inquiries. Thank you Katnich we are all in love with our new home.
Mark, Sherralee, and the entire Katnitch team were an absolute pleasure to work with. As this was our first build, we were understandably nervous, but Mark made our dream home come to life in ways we never imagined. He designed a home that perfectly suits our family lifestyle, ensured everything we were hoping for was included, and exceeded our expectations in every way.
We truly feel the team went above and beyond to ensure we ended up with a home we absolutely love. Throughout the entire design and selection process, they worked closely with us in a professional, supportive, and collaborative way. Clear communication throughout the build and having direct access to the builder (Mark) was a massive bonus.
Would highly recommend!
