Vision & mission

The living environment is the most complex interplay of interests we know. The living environment facilitates our daily lives. In order to augment, improve and modify this system, collective wisdom is needed, as well as empathy. We are practiced in our field; we understand the art of making. We bring together people, space and money in spatial developments for a sustainable living environment. We combine expertise on a social, spatial, financial and processual level, seeking optimal solutions out of seemingly contradictory interests. Content before ego. We prowl in the spirit of the place. We make immobilized processes fluid again. We work on projects that people will love; we love them, too. We watch over the dream and stand with all feet on the ground.


A wide range of assignments are addressed through a variable composition; expertise and demand are matched. We have a broad network of professionals with whom we often gladly collaborate. Dana Ponec and Katja de Winter the owners of the office. A more permanent cooperation has been established with some partners. A selection of projects can be found here.

Dana Ponec

Dana graduated from the Faculty of Architecture at TU Delft in 1988. After a period of roaming that took her to Barcelona and Noordwijk, she returned to the place of her internship, the office of Sjoerd Soeters, where she eventually became co-owner. In 2007 she split off with her core team of colleagues and clients and continued working as Dana Ponec architects. Since January 2015 she shares her office—now known as Ponec de Winter—with Katja de Winter, a supportive and reliable associate for many years. Dana occupies herself with spatial developments in the living environment and the processes associated with these, in the broadest sense of the word: as a designer, as a strategic advisor, and as a teacher. Yet this is never accomplished alone; for such a complex organism as the living environment, collective wisdom is needed. Hence the close collaboration with The Beach on the Notweg garage and Wilko Wolters through BIND!, and therefore also the advisory work for Mooi Noord Holland as an obligatory advisor, committee member, and ambassador for environmental quality.

Katja de Winter

After studying architecture at the ETH Zurich and several internships in the Netherlands and Switzerland, in 1999 Katja began working for Soeters van Eldonk Ponec architects in Amsterdam.Soon after, she started working quite frequently together with Dana Ponec. In 2007 she helped to establish Dana Ponec architects, and since January 2015 she has been co-owner of Ponec de Winter. Over the years she has gained a great deal of experience in area development, urban development projects, and the realization of buildings. Katja’s knowledge has convinced her that her line of work is not about making buildings for people, but designing places with people. She enjoys the vastness of architecture, connecting people, programs and space, at any level of scale. In addition, combining her work with music is important to her; playing violin is a great passion of hers, as is handling and organizing projects. Katja has experience on the boards of various organizations and has been chairperson of the Mokum Symphony since the beginning of 2016 (www.mokumsymphony.nl).
