During the second edition of the ‘Dag van de Ontwerpkracht’ (Day of Design Power) our colleague Mona zum Felde gave a pitch at the Masterclass ‘Op waterbasis: wat betekent het als we water en bodem echt sturend maken?’ (Water-based: what does it mean when we make water and soil truly guiding?). The pitch, together with pitches from Stijn Koole (BoschSlabbers landscape architects) and Marco Hoogvliet (Deltares), was input for a panel discussion that focused on the importance of water and soil as guiding principle, what that means for developments, and how design can both contribute and benefit from this.
