Glad to see this thread isn't actually about a real disaster!

That's not too bad... decorative screening and an assortment of potted plants can soften that up in a jiffy. Maybe some bright outdoor pillows on the furniture. Get some solar lights to give an evening glow :)

I need to see the area in context to the house so a pic from much further back and also a to scale plan to give us some idea of the size . Why are there no windows on this side ? The more info the better . Also how do you get to this area.

Get deep planters and V shaped trellises, Grow vines. Some tropicals grow ver fast so you can get it covered in a week or two. While they are zooming up you can think of a more permanent solution. Consult with your local nursery.

How about a trellis that will support a climbing vine. Might suggest a pergola that has screening of some type (lattice, etc.) that will provide a bit of cover as well as coving up the plain siding. Good luck!
