Outstanding coastal quality through building with nature
The seawall of Hondsbosch and Petten is a tough, nearly 6 km long dyke that since 1880 excludes the North Sea from the northern part of Holland. The dyke forms a thin and therefore fragile line between sea and land. Partly because the dyke has been significantly raised after the initial construction, it completely shuts of the hinterland from the sea. This problem is most evident in the coastal village of Petten. Here, the sea is nowhere to be seen and therefore the village has gradually turned its back towards the coast. Moreover, the seawall’s resistance strategy towards safety is ultimately unsafe: where the hard, immobile dyke is built on a soft foundation of sand that is subject to erosion and is therefore gradually undermined. Local history with a great number of floods has repeatedly shown that hard constructions in a sandy shore are short-lived. In this graduation project I have investigated whether a resilient, retreating movement that integrates the existing seawall in a new coastal landscape offers perspectives for both safety against flooding and Petten as a coastal resort. In the lee behind the existing seawall a new resilient coast can be developed. This can be done without giving up the entire medieval polder behind the seawall: 18th century engineering maps show plans for a back-up dyke that today still gives a good indication for the position of a sustainable coastline. First, a sufficiently high water barrier must be made on this location. This barrier can be made from clay that is extracted from the seawall, since that will now lose its function as a water barrier. The new dyke will form a new link between the coastal tows of Petten and Camperduin from which the emerging coastal landscape can be observed. By consequently making two holes in the former seawall the ‘invited’ tidal currents ensure that the zone between seawall and water barrier is filled with water and sediment, soon raising this area well above sea level. The former seawall remains present as an elongated island that acts as a breakwater for the hinterland. This island is accessed by a narrow bridge over the route of the Kamperkade, which is the former division between Pettemer and Hargerpolder. To protect the island against erosion and at the same time create a beach, this line is extended as a breakwater representing the part of the Kamperkade that in past centuries was taken by the sea. The northern opening in the seawall forms the mouth of a channel that connects the village of Petten to the inland water system of the Schermerboezem. This proves to be an excellent location for a new marina along the Dutch coast. The marina and related properties will form a new district of the village of Petten with a very distinct and dynamic character but well connected to the other districts. A second breakwater at Petten will ensure a wide beach before the seawall, protecting this part against erosion. Part of the sand form this beach will blow over the seawall, gradually turning it into a dune. Through these interventions, and especially the resulting natural processes, in the course of two to three decades an attractive, resilient coastal zone will arise. The ‘laid back’ coastline is brought in line with the rest of the Holland coast that now only the island and the village and marina of Petten will protrude from, as ‘outstanding’ features along the Dutch coast.

Master of Architecture / Urbanism / Landscape Architecture Amsterdam Academy of Architecture
Architects, urban designers and landscape architects learn the profession at the Amsterdam Academy of Architecture through an intensive combination of work and study. They work in small, partly interdisciplinary groups and are supervised by a select group of practising felÂlow professionals. There is a wide range of options within the programme so that students can put together their own trajectory and specialisation. With the inclusion of the course in Urbanism in 1957 and Landscape Architecture in 1972, the academy is the only architecture school in the Netherlands to bring together the three spatial design disciplines. Some 350 guest tutors are involved in teaching every year. Each of them is a practising designer or a specific expert in his or her particular subject. The three heads of department also have design practices of their own in addition to their work for the Academy. This structure yields an enormous dynamism and energy and ensures that the courses remain closely linked to the current state of the discipline. The courses consist of projects, exercises and lectures. First-year and second-year students also engage in morphological studies. Students work on their own or in small groups. The design projects form the backbone of the curÂriculum.
On the basis of a specific design assignment, students develop knowledge, insight and skills. The exercises are focused on training in those skills that are essential for recognising and solving design problems, such as analytical techniques, knowledge of the repertoire, the use of materials, text analysis, and writing. Many of the exercises are linked to the design projects. The morphological studies concentrate on the making of spatial objects, with the emphasis on creative process and implementation. Students experiment with materials and media forms and gain experience in converting an idea into a creation. During the periods between the terms there are workshops, study trips in the Netherlands and abroad, and other activities. This is also the preferred moment for international exchange projects. The academy regularly invites foreign students for the workshops and recruits wellknown designers from the Netherlands and further afield as tutors. Graduates from the Academy of Architecture are entitled to the following titles: Master of Architecture (MArch), Master of Urbanism (MUrb), or Master of Landscape Architecture (MLA). The Master’s
