Have you looked at the possibilities of adapting a larger or smaller model yourself? You can fold it up or make it hang from one side, as shown in the diagram below. If your shade is 5 to 10 cm shorter than your structure, you can wet it with plenty of water once it's in place to make it a few centimetres longer, stretching it gently before fixing it.
Unfortunately, our "made-to-measure" production times are a minimum of 4 weeks after validation of the quotation.
Could you give us a clear description of your project and the environment where the shade will be installed (location, exposure, height, size of terrace, presence of trees, posts, fences, stakes, etc.)?
Could you draw up a plan or diagram - even freehand - to explain the planned location of the shade, and the attachment points?
