Tietgen Dormitory, Copenhagen, Denmark, 2006 designed by Lundgaard & Tranberg Arkitekter

The principle inspiration for the project is the meeting of the collective and the individual, a characteristic inherent to the dormitory building type.

The simple circular form of the Tietgen Dormitory is an urban response to the context, providing a bold architectural statement in the newly planned area. The building's circular form - symbol of equality and the communal - is contrasted by projecting volumes expressing the individual residences. -- architect's web site

Alesia Museum, Le Pré Haut, 21150 Alise-Sainte-Reine, France, 2012 designed by Bernard Tschumi Architects

the strategy suggested creating two buildings with a simple cylindrical shape and a suffi cient degree of abstraction so that they can be inserted independently into their context and yet provide the 360° panoramic view required by each of the buildings. The envelopes adapt to their surroundings through materials, while the form of the buildings is deemphasized. By pairing the structures, committing to integrating the buildings with the landscape, and a simple round-building typology, the buildings manage to defer to the battle site while fostering a sense of respect and awe through their muted presence. -- ArchDaily

The form of the building is an irregular ring. Trees are out of, or in, or within the building. Instead of deliberately using perfect curve, the shape has been softly stretched in order to yield the roots of the remained trees. This uncertainty has actually increased the natural properties of the building. -- ArchDaily
