About Leithal Designs

Leithal Designs was founded because we believe there is a better way to deliver the highest standard interior design service in an authentic and well-grounded way.

We’re passionate about the role that good design plays in creating inspiring and truly beautiful spaces that stand the test of time. We’re driven to deliver these spaces through a process and methodology designed to make your life easy during the build phase.

We see every project as an opportunity to bring your vision to life and give you the ultimate client experience. We achieve this by using a values-based approach that puts you and your goals at the centre of our process.

We show up and bring our values consistently to the table. In our experience using this approach, we know we can translate your visions into authentic, stylish, and functional spaces by design.

What does our values-based approach look like?

We are Creative

You’ll never see your design show up in another build or fit-out.

We are Collaborative

Our clients are at the centre of everything we do. 

We’re with you, every step of the way.

We have High Standards

We’re perfectionists too.

Every detail of your project is accounted for and is of the highest standard.

We are Resourceful

We thrive on coming up with innovative solutions to the natural challenges that arise in a build project.
