With the oeuvre of the founders Maaskant and Van Tijen, Kokon has a great range of national monuments in its portfolio. Perhaps the largest number of national monuments compared to other architectural firms of today. We are part of a 90-year buro history. Our first work number was Van Tijen's grain concrete houses in 1928. In short: we love monuments.

We see restoration as an important and honorable work. With respect to the technology and materials of former times, we seek the best possible restoration of a structure so that it can weather the test of time. We are specialized in this and are happy to make our knowledge and expertise available for the rich building history in our country. Both young and old monuments are in good hands with Kokon.
