For Axel Nieberg, the creation of expressive atmospheres is paramount. Intensive light planning is always part of his creations. The Japanese wabi-sabi doctrine is reflected in his 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. The rooms should be an experience and captivate the residents and viewers. In doing so, he focuses on the aura of calm and contemplation. Voidness in connection with special lighting moods means quality for him. Omission and renunciation are always part of his thought processes. His buildings need time. Time in the mental elaboration, time in the craftsmanship and time of the viewer to experience the minimalist spatial compositions.
