What foundation should I use for this patio?

This is the space I'm working with. I need retaining walls at the bottom and sides. The gound slopes about a meter top to bottom. I've dug down to rock and am not sure whether to pour a concrete footing or use compacted aggregate to set a level. Either way I'm going to need to step the foundations at the sides to get up to the level of the window. If I use concrete I'd put concrete blocks on top as is sets, with rebar spikes going through the blocks. I'm not sure how I would put the rocks down on aggregate. Any help much appreciated. https://preview.redd.it/xbu3m6rhwrxe1.jpg?width=1600&format=pjpg&auto=webp&s=a3b048128240a27baf8e05fc04fb6ef4b0b8c570 https://preview.redd.it/l2ebyfpkwrxe1.jpg?width=1536&format=pjpg&auto=webp&s=3019721b8ca24de9e9595798fdf5674b880a8551 submitted by /u/8car [link] [comments]
