With the oeuvre of our founders Van Tijen and Maaskant, Kokon has a number of national architectural heritage sites (rijksmonument) in its portfolio. Perhaps more national architectural heritage sites than any other architectural firm in The Netherlands today. We are part of a 90-year agency legacy. Our first project was Van Tijen's 'concrete grain' houses in 1928. In short: we love our heritage.

We see restoration as important and reputable work. With respect to the technology and materials of past times, we seek the best possible restoration of a structure to allow it to stand the test of time. Restoration is one of our special skills, and we are happy to make our knowledge and expertise available to the rich building heritage in our country. Both old and more recent heritage sites are in good hands with Kokon.
