You can integrate a structure up on top of the building that doesn’t slide flat, like panels, but is sitting up on the rooftop, strictly covering an opening with no steel beams or substructure needed for panels. This structure gives the ability for 100% clear sky opening because it slides back on the rooftop, out of view from below.

You can have a half-moon, rounded retractable roof that slides back to open up to the sky. This particular project is opened up ¾ clear sky view. Full view is feasible, achieved when there is a space behind the structure to extend the tracks and further slide back the roof.

You can have an entire room that has an enclosure over it that either joins to the building side (like the Union structure pictured) or fully stands on its own (freestanding), like the structure pictured below.

This type of enclosure is used for an area that needs the architectural covering to stand on its own, without attaching to any building or framework. This structure can slide back to one end or part in the middle.

You can plan for an “end cap” dining area in the shape of a circle or half circle for a round track-less product.
