The architecture of Rotterdam-based ONL has developed with great speed into a mature new style. Intuition and logic are fused into an innovative yet consistent approach to design, and intuition has been trained to take advantage of the newly acquired digital working space. ONL is directed by Kas Oosterhuis who is currently professor from practice at the Faculty of Architecture TI Delft, and by Ilona Lenard who has been educated both as an actress and a sculptor. Together they have created their own vocabulary of powerful and meaningful terms accurately describing their visionary architecture. Their designs are created with the speed of the traffic flow passing by their buildings; they have learnt techniques from automotive design and apply these to the modelling of their building bodies. This new "Master Architect Series" title encourages a closer inspection of the European vision for the future of design.
