The Plus House is a pre-fab two-storey house with the generic proportions of a traditional Swedish bard house, designed by Swedish architects Claesson Koivisto Rune. Now the most interesting part of the house I think that is this beautiful and simple staircase. Now here are a few words about this project from the Swedish architects website : “Instead of windows positioned like regular “holes” along the walls, entire sides are glazed. On the entrance floor both long walls are glazed. On the upper floor the gable ends are glazed. Seen in plan, these two lines of vision straight through the building are perpendicular like a plus sign.” - Via - David Report
