Bricked veggie patch?

I have a stack of bricks laying at the side of my garden looking sorry for themselves! What I'd love to do it use them to build a square-ish veggie patch... can I build that on slabbing? Would I line it with anything?

I'm very much a beginner and so, stupid question alert... do I need to cement the bricks?! Can I buy ready-made cement if I have to cement them?

What I'd like to be able to do is transfer my seedlings when they are big enough - aubergine, broccoli, courgette - possibly my green beans altho they need something to climb.

Is it possible to use the bricks for this?

 

Thank you so much for your reply, just deep enough that I can plant carrots & potatoes. So yeah, prob 2 bricks? If I lay them dry, then put in some type of plastic sheeting to line it? When I fill it with the compost, would the weight of the compost push the bricks down?

 

I built it up this afternoon, and had enough bricks to go 3 high, I'll try it and see how it goes, will fill it slowly! My green beans are ready to be transplanted from the tiny pot they are in, and my aubergines are beginning to sprout shoots, so it wont be long until they go out!

 

Thanks! That did cross my mind, thankfully! I am yet to get something to line it. I need to do i real soon though as my green beans are in desperate need of bigger growing space. I'm scared to put them outdoors yet though, it's been chilly here the past week or so :(
