For the fourth book in the In Practice series, Dyvik Kahlen architects explore the design process of the Villa RuBa, located near Utrecht. Together with Fabrizio Ballabio, they develop the compositional research related to the historic typology of the villa and to the specificities of the sloping park in which it is located, and reveal how Virtual Reality is used to investigate the spatiality of the project before its realization on the construction site. Additional contributions evoke the role of annotation as a design tool, the ambivalence of a classical and vernacular project, and the entanglement of contemporary architecture with pop culture.
