MAC Design Studio is a boutique interior design studio with a focus on residential and commercial spaces that are timeless and authentic – representative of their inhabitants, and enduring in appeal.

01 about

Our work is driven by the intrinsic understanding that well-designed, finely curated spaces have the power to enhance lives. Celebrating personal narratives, supporting finely-balanced lifestyles, fostering interior connections to the special landscapes beyond; great design unlocks the magic in a place. 


Sustainability is central to our design decision-making – we prioritise quality craftsmanship and thoughtful makers, timeless design choices and natural materials that will age beautifully.

We intuitively pursue an inventive use of space, from the micro to the macro, and balance it with a clever application of materials and custom detailing. This creative focus is counterbalanced by a deep passion for the relationship between research and design;

the close collaboration between a diverse group of designers and makers is truly inspiring. In fact, this close partnership with our clients and creatives is at the heart of our unique design journey.


Working with clients in high-end residential, boutique and commercial sectors, we bring a classic design sensibility to the process, which above all is bespoke to each client.


MAC Design Studio was founded by Alan Mc Mahon, an award-winning Interior Architect with over 20 years’ of experience in Europe, USA and Australia. Alan’s career has seen him create luxury homes, boutique hotels and restaurants, wine bars, retail spaces, health and wellness spaces, workspaces and a major airline lounge

04 what our clients are saying

Alan is very easy to work with and made us feel confident from the beginning. We couldn’t be happier with the apartment Alan created exactly the look we wanted and we would not hesitate to recommend him. - Lynn O’Shea

I came to know Alan during my renovation project in 2020. At the time, my husband and I were doing a complete renovation of our apartment at The Elan building in Darlinghurst. I thank my lucky stars that Alan was available to take on my job. I subsequently referred him to my sister, who lives in NY, for her refurbishment job and she too had the exact same experience with Alan! - Viv Moushoulof

I am thrilled to write this positive testimonial for the incredible Alan McMahon. Despite being thousands of miles away, since I live in NY and he’s Sydney based, he provided exceptional guidance and advice in designing my apartment in New York when I moved into it in 2021. The end result is a space that I absolutely love being in every single day. I wholeheartedly recommend Alan’s services to anyone in need of an exceptional interior designer, regardless of the distance. - Emilia Moushoulof
