Our Ethos

Our interior design studio was formed in 2011 by Kathryn Trentini. Since its inception, Trentini Design has grown into an award winning design studio with a distinctive style and approach to the home.

We believe that our clients should connect emotionally and spiritually with the spaces they live in. We seek to understand precisely how you want to live, helping you uncover your own style and aesthetic visions, supporting you to make informed decisions. Ultimately, we create carefully considered, functional and beautiful spaces that fit your life. We want your interior to work for you and to delight you every day. We want you to feel at home.

WINNER Designer of the Year

“After making initial contact with Kathryn, she arranged to meet us at our home at a time that best suited us. The visit was very relaxed while also being very informative. Kathryn is very friendly, engaging, and knowledgeable. She was able to offer us a wide range of options and a lot of food for thought, while simplifying the design/build jargon into terms that we could understand and descriptions that we could visualise. We appreciated that Kathryn asked a lot of question in order to determine what styles, colours and finishes we favoured for the exterior of the house. No problem or question was too much trouble. In just a few weeks, Kathryn was able to provide us with beautifully presented plans of an exterior that we are delighted with. We are very excited to be able to get started now, and plan on engaging with Kathryn when we do.”
