Abstract: An architectural structure includes retractable and moveable louvres having a frame having a rear end, a front end and a pair of side walls connecting the front end and the rear end and a plurality of louvres extending substantially between the side walls, with at least one end of the louvres being mounted to a gearbox member for controlling the angular orientation of the louvre. Each gearbox member is mounted upon a track extending substantially along a length of at least one side wall and at least one of the gearbox members is mounted to a belt driven by a drive pulley to move one or more gearbox members along the track, in which each gearbox member is attached to an adjacent gearbox member by way of a connector, with the length of the connector extending between adjacent gearbox members being constant such that, when the louvres are in an extended position, the spacing between the louvers is maintained at a predetermined distance.
