As the city of Arnhem and other area developed. The precious vision of the estates are narrowing because of some reasons. The most important reason is the ‘visual obstacles’. The city developed with high rises, the high rises block some of the visual channel that belonged to the estate. Like the park Sonsbeek, the house can see the river Ijssel in the past times, which is a total different scene as now blocked by the project of Arnhem central station. The problem might because of the estate did not develop with city, or in another word the city did not follow the rule of estate. Furthermore, there is no any policy in visual regulation in the city of Arnhem. This out of touch with the city actually caused another problem which is the fragmentation. The estate has their own territory at past but connected by the main infrastructures. The fast city development lesser the area of estate territory and cut down the connections. The situation of the estates right now are like isolated islands. There also other factors that influence the sightlines and panoramas. This project is to explore the potential of spatial visual framework for preservation and development of estates landscapes in urban context and to safeguard and develop the spatial visual qualities of the estate themselves.
