                                                             Our clients say

I contacted ett koncept. since I had a new flat to furnish from scratch. I am extremely satisfied with the result since I thrive and feel extremely happy with the interior. Everything went very smooth and Celine had the eye for how I wanted it. I can really recommend ett koncept.

- NHL player Kristian H., private home, Nacka

"I am incredibly impressed of how the colors, design and furnishing have been mixed together to what now has become my dream home. 10 out of 10 stars!​"

- Niklas, resident in one of the pods designed by ett koncept at Tech Farm - a co-living space, Östermalm, Stockholm


"We hired ett koncept both to renovate and furnish our home with color and warmth and we only had a very diffuse idea that Celine at ett koncept helped us to gather and make reality off, which was not an easy assignment. We wished for a home that doesn't look lika any else we've seen, yet also a harmonious one.

The end result has become exactly what we wished for, which we could never even have imagined when we started. We couldn't be more satisfied! During the project work, Celine was always accessible, very creative and positive in all situations. We highly recommend ett koncept and Celine!"

- Mia and Thomas, private home, Östermalm, Stockholm

"We liked everything that ett koncept delivered but what really impressed us is how they managed to exceed our expectations with a style that really feels like us! The color combinations and interior that we would never have dared to choose ourselves are very timeless, yet exciting and shows our personality."

- Diar and Aso, private home, Solna

My company hired ett koncept to design our reception room for therapy. It is a very important room where me and my clients need to feel calm and safe, which I found hard myself to achieve. Celine at ett koncept managed to capture my style and my wishes and came up with lots of interior details that I would not have known how to find myself. The result was a calm, safe and representative wholeness. Many of my clients have told me that there is a feeling of peace and tranquility in the room. My company will definitely hire ett koncept again and I highly recommend them!
