The Amsterdam based studio was founded by Tanja Buijs-Vitkova in 2001 and innitially was functioning parallel to her design work at the foremost Dutch studio Uytenhaak. Her expertise ranges from residential to commercial and public buildings, many of them award winning and published by international journals.

Alongside working at her firm, Tanja works as visiting lecturer at Delft Technical University and for op ten noort blijdenstein studio in Utrecht.

representative is strongly conceptual and broad contextual approach, that combines the good amount of spacial and technological experiment with pragmatism and smart sustainability |

philosophy |

Architecture is about making space. It‘s shape, it’s physical characteristics and perception as defined by it‘s boundaries. Putting those boundaries in relation to the context, creating or breaking them down, as well as their interaction and quality, forms the red thread of her design work.

Her design approach is characterized by a powerful concept, based on a detailed examination of the program in relation to the spatial and social-economic context. The result is a sometimes surprising but always pragmatic architectural solution, giving room to a balanced combination of spatial and technological experiment.

The new typological and spatial solutions for several dutch universities, as a response to changing research- and educational processes (e.g. Life Sciences and Eriba Groningen, VU University Amsterdam) and new housing typologies as a respons to new ways of life are some examples of this approach.

The current social-economical context is also being mirrored through the theme of sustainability. Typical is the effort in finding simple, no nonsense, low-tech solutions that could be called a sort of "back to the future" approach. Sustainibility if seen as a basic quality, unavoidably transforms concept and expression into new archetypes. (Dutch embassy Canberra, Australia)

Her broad interest on current technological developments results in applied product development, often in cooperation with producers.(e.g. composite façade panels - LifeSciences )
