KT71 Interior architecture and lighting design

Everyday comfort

About the vision
When you stay in one room for more than 10 minutes, you need comfort. Comfort gives people a sence of feeling home.
In my projects, people are the priority. Comfort is crafted through light and design, which brings out the lively spirit of the people in the room.
