Fashion model Isabelle Mathers and her partner Harri Musumeci are the high-profile new owners of The Valle Casa in the Gold Coast Hinterland – formerly the family home of entrepreneur and content creator Ellie Watson and her husband, Alex.
Leading up to its November 2025 auction, the property was reportedly the most-viewed home in the country, and the event itself attracted a crowd of 200. Six serious bidders – including the model couple – vied for the impressive estate, yet it was passed in at $5.9 million.
Negotiations continued behind the scenes, and Isabelle and Harri went on to secure the five-bedroom residence with two wings, open-plan living, entertaining deck, pool and rainforest outlook, all extensively documented on social media during the design and build process.

The final sale price has been kept under wraps and marketing agent Christina James of Amir Prestige told RealEstate.com.au “they didn’t want to be showy”. Motivation to make the mansion their own clearly wasn’t lacking, with Isabelle telling the property site they “had that unspoken ‘this is it’ moment” when they walked through the home.
Ellie Watson’s Gold Coast home: From vision to completion
Thousands followed along on social media as lifestyle entrepreneur Ellie Watson documented the building process for her new home on the Gold Coast. It’s been described as “a Mediterranean-style build with mid-century and modern Australian influences” and she shared the impressive five-bedroom property with husband Alex, their two children, Bowie, 5, and Zimi, 3, and their dog, Oatly.

Ellie rose to fame in the earlier days of Instagram as Ella Bullen (before she took Alex’s surname), creating recipes for Elsa’s Wholesome Life. We watched as Ellie shared mood boards, selected materials and got excited about the process of creating the couple’s dream family home. The final furnishings were still being unboxed in December 2024, before brands they worked with started sharing glossy footage of the home’s final reveal in January 2025.

Less than a year later, in October 2025, it was revealed they letting the home go. The founder of fashion and lifestyle company The Wholesome Store had some surprised reactions to the listing. “People are a bit shocked we’re selling,” Ellie shared with RealEstate.com.au. So, why is the family moving on so soon? “We built it with the intention of it being our dream home, but I loved the creative process, so we’re keen to do it again,” she added.

Surprise or not, this famous one-of-a-kind find was a real-estate dream, with finishes that are modern, minimalist and very on trend.

Nestled in the Gold Coast Hinterland, the pair purchased the piece of land in 2021 before undertaking a lengthy process to bring their vision to life. They worked with designer Luke Holmes, builder Arluca Construction and interior designer Mi Zepp Studio to turn it into a reality.

“The design was inspired by European architecture – especially Italy and Spain – but with modern Australian and mid-century influences,” Ellie told Domain. “We were really hands-on throughout the process – ordering samples, visiting the site and making final design decisions.”

The result is The Valle Casa, a modern Mediterranean style home that’s instantly recognisable as the place where the family did birthday cake bake-offs and videos sharing their lives.
Now, it’s set to become the home of Isabelle Mathers and Harri Musumeci, whether that’s for now or forever.
