What is your style?
What colours and textures do you like to be around? Do you want to live in an eclectic, classic or vintage interior?

So you say you’re not sure?
You do know what you want. The only thing you need is a specialist who asks just the right questions and listens to what you say.

What matters in One Design is…
…above all, your individual personality and your dreams of the perfect flat. We just listen to what you say and design interiors you’ve always dreamt of.

Founders of ONE Design


Agata Filipczuk

Co-founder of One Design, Agata has been working in the design market for over a decade.


Her natural taste and sense of style were further sharpened in Italy where she spent a few years. Her love for Italy still thrives, and her annual visits to the Milan fair are a guarantee that projects by One Design are not only timeless but also in line with the latest trends.


Not only is she an avid reader, but she also loves to cook. Her favourite way to spend holidays involves sailing or hiking in the mountains
