Folding arm awnings, for the space with no roof
A folding arm awning cantilevers out from the wall on hinged arms with nothing at the outer edge — no posts, no frame, nothing to walk around. It retracts flat against the building when you want the sun back or the weather turns. That combination is why it suits a courtyard, a paved terrace or a deck that was never built with a roof: you get shade through the afternoon and the space back in winter. Retractable awnings are the same thing under a different name, and either way the span and the projection are set by what the wall behind can carry, which is a measure-appointment question rather than a catalogue one. Our Gold Coast awnings page goes into which of the two suits an exposed elevation and which does not.
