Purpose: There are many factors that affects the interior prospect in a teaching environment and the difficulty is to find a balance between seclusion and openness. The aim of the study is to examine the interior prospects impact on a teaching environment and which opportunities and limitations the lines of sight gives depending on how the have been designed.

Method: This is a qualitative study and the used method is a case study of a F-6 school. A literature study and interviews were used as the data collecting technic. The interview with the principal of the school, the architect in charge and a co-architect for the same schools were performed.

Findings: The results of the literature study and the interviews gave that the factors that affects the interior prospect were flexibility, relationship between the different functions, extent and visual environment. In the result different parameters emerged that were conducive reasons to the factors. One of the parameters for flexibility were form, for the relationship between functions one was placement, for extent one was size and one parameter for visual environment were the share of transparent surfaces. The result showed that the stance on the interior prospect between architects and teachers accords with each other.

Implications: The conclusion of the study is that there are distinct parameters that cooperates with each other to create an interior prospect, but there are no obvious solutions since there are no general solutions to the problem.

Limitations: The case study is only implied on one school. This choice was made to get a deep understanding of the reality and to get at overview of the parameters that has an impact on the interior prospect. For the result to be more generalized more schools had to be studied to see if more parameters were to be find.
