Parks play an important role as restorative places in urban areas, and it has been shown that even small urban parks can fill this need, but to a varying degree dependent on the content and size (Nordh et al., 2009). Small parks have a disadvantage in relation to large parks in that you cannot escape the impact of the surrounding buildings and streets just by walking further into the park. Hence it is likely that the properties of the edges are especially important to consider in the design of restorative small urban parks. Spatial borders and their openness, what you can see and by whom you can be seen, has a prominent place in some of the main theories of the field. For instance Prospect Refuge Theory (Appleton, 1975) promotes that enclosure, such as cover behind ones back, is important for the possibility to relax. As found by other researchers enclosure, such as a dense vegetative edge, can also promote the feeling of entering a whole other world, an experience that in the vocabulary of Attention Restoration Theory (Kaplan, 1995) is referred to as a sense of Being away.In this study we will explore the impact of enclosure on the likelihood to rest and recover from stress. Based on an existing small urban park, that in a previous study scored medium on a restorativeness scale, we have built a digital model in which the park content is kept constant while the closure of the edge differ from open (no edge vegetation) to semi open (only trees) to enclosed (trees and bushes). These are edge conditions that would also be commonly found in practise. Each park model will be experienced by an independent group of subjects by means of a pre-fixed walk from outside the park, via the edge and into a central point of the park. Questions about restoration and the sense of being away will be asked. Results will be presented at the conference.
