ABOUT US
We are Juriaan and Rianne — partners in both life and design and the heart behind New Tradition. Our shared passion for architecture, interior design and creating meaningful spaces has driven us to build a studio dedicated to helping people turn their visions into reality.
Design is more than a profession for us — it’s what inspires us every day. Whether we’re sketching layouts, choosing materials or overseeing a construction — we pour our creativity, expertise and care into every project. Nothing excites us more than collaborating with clients to craft spaces that reflect their unique stories, personalities and needs.
Our approach is simple but impactful: Design. Build. Deliver. From concept to construction, we provide comprehensive services tailored to your goals. With the option of working alongside our in-house construction team or managing external contractors — we ensure every detail is handled with precision and transparency.
We believe great design is not just about aesthetics — it’s about creating spaces where life happens. Places where families grow, businesses thrive and memories are made. That’s why we approach each project with dedication, curiosity and a deep commitment to understanding what truly matters to you.
Let’s create something extraordinary together!
JURIAAN CALIS
Architect & Technical Director
We believe that a space should be fundamentally beautiful and completely functional at the same time. Our mission is to find the right balance for every aspect of the architecture and interior design — leaving room for the unexpected, creating comfortable spaces that give joy to our clients every day of the year.
RIANNE TOONEN
Designer & Managing Director
For New Tradition, creating a beautiful space goes beyond aesthetics. A space must inspire our clients. When a space triggers your senses and emotions by its beauty, harmony and personality, that is when we have reached our goal. It is not just simply building, painting and adding furniture — it is as the creation of a symphony, where every detail matters.
“Our passion for spaces and
surroundings made us automatically
fall in love with nature too.”
We care for nature deeply, and therefore sustainable living is very important to us. We need to take care of our planet, and every step – big or small – makes an impact. We are very eager to guide our clients forward in this mission. We advise for durable, natural materials and furniture that lasts for years – investment pieces rather than throw away, fast furniture.
New Tradition also creates energy concepts in which we balance energy, comfort, aesthetics and budget. We have worked on multiple monumental houses and always successfully maintained the characteristics of the building whilst making it a comfortable place to live in – in the winter and summer times. During our projects we work together intensively with our team of energy consultants, who are up-to-the-minute regarding insulation, heating, cooling and all the other latest technologies.
In all our designs the original architectural details are celebrated and combined with clean modern gestures – blending the traditional with the new. These two opposites do not have to be contradictions. The one is actually the result of the other. What currently seems traditional, once was new.
