The Japanese wabi-sabi doctrine is reflected in Axel Nieberg's choice of materials. Natural materials weather over time, enhancing their beauty. His buildings are often characterized by solid materials such as exposed concrete and brick. For Nieberg, the creation of expressive atmospheres is paramount. Intensive light planning is always a part of his creations. His rooms should be a captivating experience for residents and viewers with a focus on establishing an aura of calm and contemplation. To him, quality means establishing a connection between special lighting moods and the void. Omission and renunciation are always part of his thought processes. His buildings need time. Time in terms of mental elaboration, time in terms of the craftsmanship and time in terms of how the viewer experiences his minimalist spatial compositions. Nieberg's comprehensive approach to design ranges from architecture and interior design to furniture and product creation. Open space planning is also a major theme of his studio. Its areas of responsibility are very diverse and range from large scale to small tasks. For Nieberg, the size of a task is not important, what matters is that each is executed to the highest standards.
