Completely amateur question - i want to build two parallel block-work walls on my sloped driveway. Usually if you use normal bricks or even sometimes blocks, you can have "steps" / levels; where the bricks gradually get lower and lower, but i want the top of my blockwork to be completely level. So i was thinking at the rear of my driverway, the side closer to my house, the concrete footing could be at ground level, then i can build some wooden formwork so that near the end of the driveway the footing goes above ground level. That way the wall would be relatively shorter at the beginning of the driveway but at least the height would be even. The driveway is 5 metres length and 6 metres width. I have attached a side-view sketch of what i propose, the brown line is the ground level and the grey box is the footing and the yellow are the blocks. Let me know if this is an "ok" idea or if someone has better ideas?
Thanks!
