Conscious Living.

Considered Design

Meet the woman behind
Darwin’s most refined interiors.

At JMJ Interiors, we believe luxury is not just about how a space looks — but how it makes you feel. Our clients come to us when they’re ready for something more: more ease, more elegance, more intention. They’re busy professionals and high achievers who want a home or workspace that reflects their success and supports their lifestyle — without the overwhelm of managing it themselves.

At the helm is Jan-Marie Jaillei — Darwin’s most sought-after interior designer and the trusted authority in elevated, soulful design.

"We recently engaged JMJ Interiors to help us reimagine and renovate our apartment, and the experience has been nothing short of awesome. We love it! Thank you, JMJ Interiors and team!"

- Cameron M

"We recently used JM's services for a large interior renovation, and would highly recommend! JM understood the vision for the renovation and delivered designs that absolutely hit the brief."

- Jordy B

OUR Philosophy

Design is personal. And it should feel effortless.

At JMJ Interiors, we take a personal, considered approach to every project. Our process begins with listening — to your story, your goals, your vision — and evolves into a space that feels effortless, elegant, and completely your own.

Our philosophy is rooted in:

Clarity

A clear, structured process that keeps you informed and empowered.

Calm

We remove stress, manage the details, and handle everything behind the scenes.

Craftsmanship

From spatial planning to styling, every element is purposeful and high-quality.

Transformation

We create not just beautiful rooms, but better ways to live and work.

Whether you're building, renovating, or restyling, we’re here to make your experience seamless — and your result unforgettable.

What sets JMJ Interiors apart?

Industry Leadership

Jan-Marie’s reputation in the design community speaks for itself — she’s not only a practitioner, but a voice of influence and excellence in the field.

Full-Service Expertise

We offer a complete, turnkey service — managing everything from concept to final installation — so you can enjoy the process without distraction or delay.

Architectural Insight + Emotional Intelligence

Our work combines structural logic with human emotion. We design for the eye and the soul — which is why our clients say their spaces don’t just look good, they feel right.

A Truly Boutique Experience

We work with a select number of clients each year to ensure our full attention, creativity, and care. When you work with JMJ Interiors, you are our priority.

Trusted by clients who value results

"JM was simply amazing! From the very start at the initial meeting JM was across everything and made us feel very comfortable that she had everything under control. As expected with a renovation things can go wrong but nothing was ever to hard or anything that JM couldn't fix and was always available. The process from start to finish and the experience was very enjoyable and we would absolutely be using JM in the future for all of our projects. If you want the best, JM is your go to!"

- Andrew H

"Blown away by JM’s work. From the moment we spoke I knew I’d found the exquisite talent I was dreaming about…. She delivered us with an absolutely sensational new kitchen that has completely transformed our home. On time. Within budget. Whats not to love! Every element was carefully considered and flawlessly executed by her & her super talented team. My favourite items are things I didn’t even know I needed in a kitchen! It’s swanky AF, it’s functional… and it’s exclusively mine. Designed and built just for me!"

- Nicky M

Who we work with

Our clients are leaders, professionals, entrepreneurs, and creatives — people who want their home or business to reflect who they are and what they’ve built.

They value excellence, trust their instincts, and expect high performance. Most importantly, they don’t want to settle for a generic solution — they want a space that is beautifully, authentically theirs.

Where we work

While we’re proudly based in Darwin, JMJ Interiors takes on residential and commercial projects across the Northern Territory and beyond.

Whether it’s a luxury coastal residence, a boutique hospitality space, or a modern executive office, we bring the same standard of excellence and bespoke service to every brief.
