Nikolai Lieblein Røsæg is an architect and a scenographer working at the intersection of performing art, visual art and architecture. He holds a masters degree in architecture from the Oslo School of Architecture and Design (AHO) and from the Royal Danish Academy of Architecture (KADK).

Liebleins work focuses on site interactions, experiences of specific spaces, and material investigations. He uses architecture as a tool in interdisciplinary collaborations that explores and discuss place as a geographical, cultural and social space. He works through a theoretical, intuitive and exploratory process with surroundings, materials and drawing, which are translated into visual expressions, distinctive spatialities and sculptural forms. Nikolai is part of the international artistic collective Liavaag/Lindberg. He is also a co-founder of the architecture collective Klubbkontor, and practices as an architect at Skajaa Architecture office.
