Hi Mrs A - if you have a lot of concrete at the base of the structure, you're really limiting yourself. If you can't get climbers into the ground, it would be best to build some really generous sized planters in order to get a good result. Climbers in particular need a decent amount of root run. Depth is more important than the other dimensions too.
The area where the laurels are could be a possibility, but only if you have sufficient clear space between them and the structure. You'd have to be very vigilant with watering and feeding (especially till plants were established) as Laurel will leach a lot of that.
I'd personally build some decent raised beds or you'll always struggle to get things looking at their best. It can be done quite cheaply with timber
