About

A residential design studio grounded in architecture, proportion and material, creating thoughtful, cohesive homes designed to feel calm, balanced and enduring, shaped by the way people live.

Established in 2013, Halvorsen Interiors is a residential design studio specialising in interior architecture, spatial planning and interior decoration. The practice brings together architectural discipline and interior sensibility to create homes that feel cohesive, calm and enduring.

Working across renovations, new builds and full furnishing projects, the studio approaches each commission with clarity and rigour. Spatial planning and proportion are carefully developed early in the process, establishing the framework that guides all subsequent design decisions.

The studio’s work is defined by a restrained material palette, refined detailing and an emphasis on spaces that feel balanced, functional and quietly sophisticated. Interiors are designed to feel timeless rather than trend-driven, allowing architecture, light and material to shape the experience of the home.

Halvorsen Interiors remains intentionally small in scale, allowing for close collaboration and direct involvement from concept through to completion. Strong relationships with trusted trades and suppliers, combined with clear documentation and communication, ensure each project is delivered with care and precision.

The Studio

The Halvorsen Interiors studio is where ideas are developed and brought into focus.

Designed as an extension of our practice, it is a calm, light-filled environment anchored by custom joinery and layered materials. It provides a structured setting for consultations and presentations, allowing clients to engage directly with selections and review concepts with clarity.

Our dedicated sample library houses flooring, carpet, natural stone, tile and textile collections, providing a tactile space where material decisions can be explored with confidence.

Consultations are held by appointment.

  • "We engaged Jess to design a renovation of our home in Burrawang. From the first meeting we felt in very safe hands. Jess understood the different life stages of our children, appreciated the way in which we liked to live and designed our house accordingly. We loved our old house that we’d been living in for over 10 years and somehow Jess managed to keep the feel of the original while at the same time delivering something beyond what we could ever have hoped for. Throughout the whole process, Jess and her team provided a guiding hand through the endless choices that had to be made, all while listening to us and understanding what appealed to us. In the end, it wasn’t just a house that was renovated and rejuvenated but also our way in which we live in it every day. We can’t thank Jess enough."

  • "I have recently been lucky enough to spend quite some time working with the delightful and talented Jess Halvorsen. She was with me the first time I sat down with my architect and didn’t leave my side until we moved in a year and a half later. She amazed me with her knowledge and skill in all aspects of interior design from stunning custom joinery, assisting with the plans and of course with the interior decoration. She is an absolute delight to work with and I wouldn’t hesitate in recommending her to anybody."

  • Jess’ expertise and advice has guided us from concept to completion. Jess completely understood both our desired style and functionality that we required and as a result we absolutely love our completed house!

We thoroughly appreciated Jess’ knowledge and expertise which is still called upon as we add further touches.
