Nidus develops and designs architecture projects for contemporary living and creates cultural experiences. As specialists in the development of existing buildings, Nidus is always looking for the next forgotten story to be told.

Group 2 Chapters


Contemporary life is not a condition, it is a process. As a matter of fact, our buildings must be designed in such a way that they can respond to this process. This is what drives Nidus: to observe, explore and experiment to build the best possible houses for our societies.

Focusing on the transformation of existing buildings, Nidus´ portfolio includes projects from the 1890s through the 1950s and 1970s up to today.

Inspired by life and the everyday, Nidus has developed a subtle yet iconic architectural language. A new simplicity, clear structures and high-quality materials create atmospheres of uncompromising quality. Nidus interior objects arise from the own projects: designed as travel companions, they carry on the story of a physical place. 

In addition to its own project development, Nidus advises on the restructuring of property portfolios and also offers architectural and interior design services in selected cases.

The most beautiful part of architecture is that it surrounds us everywhere, but even more than that: it provides the stage for life in all its facets. Building Culture means going beyond: with a curated program of exhibitions, lectures and cultural projects, Nidus opens its doors for encounters and to experience the wide spectrum of architecture.

The owner-managed company was founded in 2016 and is 100 per cent owned by the founders Ana Vollenbroich and Annelen Schmidt-Vollenbroich. The lawyer and the architect met while studying real estate economics and immediately shared a passion for architecture. Together with their team, they develop a diverse range of architectural projects.
