The old indoor-outdoor houses had a gallery, an element that providing the rooms with light and fresh air and worked very well. However, this model is no longer accept by law, as it juxtaposes several rooms.
Of all things, Can Pep Simó is mostly a matter of distribution. A townhouse with a garden, a covered porch and two windows to the outside. The opposite area on that floor does not have natural light, which meant that only one of the rooms would take profit of it and have an exit to the garden.
By means of an enclosure of sliding wooden panels – a Trombe wall – , the Can Pep Simó porch can be closed in winter and keep the rooms at the center of the house warm during the day. In summer, it keeps the heat away from them. Moreover, it allows to put a later end to the garden activities in summer and offers light and protection in winter, being suitable as an office or as a children’s playroom.
