HOLISTIC INTERIOR DESIGN
At 369, we create homes that calm and restore the nervous system. Rooted in neuroscience and therapeutic principles, we design with the awareness that how you feel, who you are, and what you’re going through can be supported by the space you live in.
Matias Mana Prieto - Interior Designer
How we work together
Discovery session: Every project begins with a conversation. A free consultation — online or in person — I take the time to understand your vision, your lifestyle, and the energy you want your home to hold.
We also discuss timeline, budget, and the scope of the project so everything begins with clarity.
Concept and Design: Based on our conversation and the characteristics of your space, I develop a tailored design concept rooted in the 369 philosophy — aligning layout, materials, and atmosphere with the way you live.
Feedback: I present the concept and walk you through the design decisions. Your feedback is an essential part of the process, and together we refine the details until the space truly reflects you.
Project Management & Implementation: I handle sourcing, ordering, delivery coordination, and installation so the process remains smooth and stress-free. You can be as involved as you wish — from hands-on collaboration to simply enjoying the transformation as it unfolds.
Installation & Energy Setting: The final stage is where everything comes together. I oversee the placement of every piece so the space feels balanced, intentional, and complete.
If you’re ready to transform your space, or simply want to explore what might be possible — I’d love to hear about your home.
BOOK A CONSULTATION WITH MATT
Hello!
I’m Matias, the designer behind 369 Interior Design.
After working with homes for more than fifteen years, I started noticing how deeply a space affects your daily life — from the way you wake up in the morning and relate to others through the day, to how you deal with stress and rest in the evening.
“ interior design is a form of therapy — a daily wellness ritual for the nervous system.”
The spaces we live in can support clarity, focus, and recovery. When proportions, light, materials, and atmosphere come together in the right way, a home becomes a place where the body naturally settles and the mind finds balance again.
My work grows from this understanding. I focus on creating spaces that quietly support who you are, and who you are becoming.
