About
Born to a Dutch father and Portuguese mother, Stephanie grew up with a rich blend of cultures that shaped her design philosophy. After earning a master’s in Marketing, working for multinationals, and living across the globe, she realised her true passion was always interior design and craftsmanship.
In Mexico, she discovered her entrepreneurial spirit by upcycling vintage vases into one-of-a-kind lamps, blending sustainability with creativity and sparking her journey into design. Stephanie later completed an Interior Design Diploma at the National Design Academy.
Stephanie loves uncovering unique pieces such as textiles, artisan objects, antiques; and giving sustainable treasures new life and purpose in a home. Having lived abroad for many years, she knows the value of feeling truly “at home in a rented home” crafting spaces that are warm and authentic.

Testimonials
Berdine
"When we moved from a condo to a landed home, we wanted our living room to feel welcoming, warm and practical - a space our family could really live in. With three young boys, buying everything new just didn’t make sense, and Stephanie completely understood that. She found the perfect balance between new and pre-loved pieces, even working in items from our travels and time abroad so everything feels cohesive and personal.
She introduced us to shops and fabrics we’d never have discovered ourselves, and showed us how much warmth, texture and colour can bring. Her idea to paint the walls, which you would normally maybe not consider in a rental, made such a difference. She even found a clever way to cover a large mosaic that wasn’t our style, turning it into a feature we actually love now.
Stephanie was a joy to work with. She’s thoughtful, responsive, and full of great ideas. Our living room really feels like home now. It’s warm, inviting, lived-in, and completely “us.” We couldn’t be happier with the result."

"We are very pleased with the interior decoration transformation performed by Stephanie. She was very patient with us during the process and managed to effectively interpret our oftentimes vague descriptions. We're particularly grateful that Stephanie held firm to her coherent design theme, despite our numerous distractions and side tracks due to our indecisiveness. Our family truly enjoys being in the redesigned space and we feel proud to show it to our friends. Thank you Stephanie."
Hatice
"I am so grateful for everything you’ve done for us. Thanks to your extra time, patience, and kindness, we now have a home that feels incredibly cozy and comfortable. My husband was initially skeptical, but now he’s even happier than I am and takes so much pride in every detail of the house!
Through every life situation that came up during the process, your patience never wavered. I'm so glad to have met someone who designs with so much heart and genuinely wants the best for people without being calculative. Thank you for making such a wonderful difference in our lives!"
Sophie
“Stephanie has been a huge help and inspiration in lifting our plain living area to having a "relaxed coastal feel". From the initial ideas phase she was not only committed to the end, but always open sending me extra advice and inspiration whenever I asked for it along the way which was very helpful. Her ideas and suggestions aligned well with my brief and she also gave me courage to take bold decisions which have massively paid off! She worked very fast and was very approachable. I look forward to more interior styling projects with Stephanie in the future! "
