Hi, bumping your dilemma :-)

paint it black.

Thank you we did think of painting it black but obviously there is no going back once done. At the moment that is just render but will definitely consider it.

Thanks Emily - we did think of growing a plant through it but left it too late this year. Maybe it draws your eye to it rather than away!

Consider the following:
Remove the existing small trellis from the wall;
Paint the rendered part of the stack in a dark colour;
Trellis the rendered part of the stack above the bend - make it substantial to ensure coverage;
Install a tall statement pot at the base of the stack;
Plant and grow jasmine up the support (choose from winter or summer flowering);
Enjoy the lovely fragrance when you exit to your outdoor space and admire the pale delicate star shaped flowers.

Thanks so much that sounds like a great idea - do you think I should paint the trellis the same colour to blend in?

It will not take long for the jasmine to cover the structure so colour will not be that crucial. Your paving looks lovely - you could always paint the trellis in a similar colour. Garden Shades do a couple of greys and coverage lasts for years. Good luck with your project.

Thanks to everyone that commented here is the result

Looking very smart. Well done.

What else have you done apart from painting it?

Hiya put up some trellis to grow a wisteria.
